Fluid and Filter Lineup for Jeep Gladiator 3.6L V6

[g2020]

Content: Part numbers, material standards, industry standards, fluid capacities, longevity, longevity limits, recommended & required service intervals, and OEM and/or aftermarket product recommendations

Coverage: Brake fluid, cabin air filter, engine air filter, front differential fluid, motor oil, oil filter, power steering fluid, radiator fluid, rear differential fluid, transfer case fluid, transmission fluid, and transmission oil filter

Key takeaway: In general, the service interval for severe service or trailer towing is 40% to 50% of the service interval for normal driving
- Applies to all fluids & filters: In addition to following much shorter service intervals for power train fluids, brake fluid, and all filters as noted below, be sure to follow recommended frequent inspection of steering components, including power steering fluid, and annual/seasonal inspection of antifreeze

What is Severe Duty?​

- Severe Duty is any operation of a vehicle that causes excessive heat​

1. Aggressive driving
2. Driving in a dirty & dusty environment
3. Driving in hot weather (above 90°F/32°C)
4. Frequent starts & stops (local driving or commuting)
5. Frequent trailer towing (usually listed as a separate category because it also affects the drivetrain)
6. Frequent trips at high speeds (above 70 mph / 110 km/h)
7. Hauling heavy loads (usually listed with trailer towing in a separate category)
8. Long periods of idling or low rpm
9. Off-road vehicle use
10. Plowing
11. Regularly driving in mountainous or hilly terrain (paraphrased from Google search)
12. Sporty driving (quoted from ZF document #4)

...not to mention anything else that causes excessive heat, such as overdue oil/fluid/filter maintenance or mechanical repairs​

​

- In extremely cold climates, an engine block heater and a battery tender can be used to keep the motor oil & antifreeze/coolant warm and the batteries from freezing. For the 3.6L (gas) engine, use API Certified, MS-6395, 0W-20 synthetic motor oil. Fill up fuel tank locally to ensure proper fuel blend. As a rule, do not let fuel gauge drop below half full. Maintain proper concentration/mix of antifreeze and healthy batteries.​

Fluid & Filter Lineup

Tips:

1. For your vehicle, confirm part numbers, material standards, industry standards, required tools, torque specifications, and a level work surface
2. Fluid capacity: Actual fluid capacity can vary depending on the condition of a component; guidance on proper fluid level can vary slightly by component (see your owner's manual and existing threads on this forum); in this article, capacity is also referred to as "required" (as in required before starting a job)
3. Know the code: The Sales Code for your vehicle enables you to determine the correct grade of fluid for the rear differential, as shown on p. 234 of the 2020 Gladiator owner's manual; also see "Notes on trailer towing" in section 9.2 below
4. For oil drain plug (MOPAR 06513414AA), use a 1/2" (not 13 mm) box wrench, or box end of combination wrench, to avoid rounding the flats, and reinstall drain plug using a torque wrench with a 1/2" (not 13 mm) 6-point socket and 20 ft-lbs of torque to avoid crushing the molded gasket
5. For brake fluid, do not use fluid from an old opened container
6. Easy jobs: Change cabin air filter, change motor oil & filter, change or clean & oil engine air filter, change transfer case fluid
7. For each product (except motor oil), MOPAR part number is provided; for each fluid, material standards and industry standards are provided
8. Although some mobile devices display UPCs as phone numbers, each 12-digit UPC (universal product code) in this article is not a telephone number
9. The list of options in this article is not final; the use of a different product is fine as long as it meets or exceeds manufacturer specifications (including material standards starting with MS- or MS.) for this vehicle, or for other vehicles with the same specifications, as listed in the 2020 Gladiator User Guide (owner's manual)

Fluid & filter uniformity:

With some exceptions, all Gladiators from the factory, for all trim levels and model years, use the same fluids & filters as of December 2024

Exceptions:

1. ATF, for transmission, is different for automatic vs. manual
   1. ATF, for any transfer case, is the same
2. No transmission oil filter in manual transmission
3. No clutch fluid (same as brake fluid) in models equipped with automatic transmission
4. Motor oil is different for gas vs. diesel
5. Oil filter is different for gas vs. diesel
6. Rear differential fluid grade varies depending on two factors:
   1. Sales Code, as noted on p. 234 of the 2020 Gladiator owner's manual
   2. Trailer towing, as noted on last page of internal dealer spec sheet; also see "Notes on trailer towing" in section 9.2 below
7. Cabin air filter part number can vary by model year

- Section tags: compatibility, compatible, consistency, consistent, identical, interchangeability, interchangeable, same, sameness, standardization, standardize, standardized, substitutability, substitute, suitable, suitability, uniform, uniformity
- Out of scope in this section: Fuel, fuel filter, windshield washer fluid, A/C refrigerant oil, and (other) diesel-only fluids & filters

Details by individual fluid or filter:

1. Brake fluid:

1. MOPAR 04318080AD MS.4574 DOT 3 SAE J1703 Motor Vehicle Brake Fluid; 2020 Gladiator User Guide (owner's manual) recommends inspecting, and replacing if necessary, brake components at every oil change; if DOT 3 SAE J1703 brake fluid is not available, then DOT 4 J1703/J1704 is acceptable (see internal dealer spec sheet); check with dealer for capacity; 12 fl oz size from dealer or MOPAR eStore

2. Prestone Synthetic Brake Fluid; DOT 3 SAE J1703; 50,000 mi; 2020 Gladiator User Guide (owner's manual) recommends inspecting, and replacing if necessary, brake components at every oil change; if DOT 3 SAE J1703 brake fluid is not available, then DOT 4 J1703/J1704 is acceptable (see internal dealer spec sheet); check with dealer for capacity; 12 fl oz size; part number AS400 (UPC 7 97496 87642 3) from Walmart

Note: On December 12, 2024, the Prestone product finder specified this brake fluid for a Jeep Gladiator equipped with the 3.6L V6 (gasoline) engine, but not for diesel (I am just reporting the facts); compliance with material standard MS.4574 is not stated on the label, but compliance is inferred for vehicles displayed in the Prestone product finder​

2. Cabin air filter:

1. MOPAR 68535621AA Cabin Air Filter; 20,000 mi or 2 yrs, whichever comes first; part number varies by model year; from dealer or MOPAR eStore

Note: Although it is not mentioned in the owner's manual, it is common knowledge that dusty or off-road conditions can make it necessary to replace the cabin air filter more frequently than the recommended service interval​

3. Engine air filter:

1. MOPAR 68257030AA Air Filter; 30,000 mi or 3 yrs, whichever comes first; the 2020 Gladiator User Guide (owner's manual) recommends replacing the filter every 30,000 mi or 3 yrs, whichever comes first and, if using in dusty or off-road conditions, inspecting the engine air filter at every oil change; from dealer or MOPAR eStore

Notice: FRAM websites have been taken down. First Brands, the parent company of FRAM, is bankrupt as of September 2025. In this post, references to the FRAM engine air filter and oil filter, for the Jeep Gladiator, are shown in strike-through font. According to a Reddit post, this has also affected Champion Laboratories.

2. FRAM ULTRA AIR Premium Air Filter; 40,000 mi or 4 yrs, whichever comes first; the 2020 Gladiator User Guide (owner's manual) recommends replacing the filter every 30,000 mi or 3 yrs, whichever comes first and, if using in dusty or off-road conditions, inspecting the engine air filter at every oil change; SKU XGA12373 (UPC 0 09100 57934 8) from Walmart

3. K&N Performance Lifetime Engine Air Filter; up to 75,000 mi between cleanings; if using in dusty or off-road conditions, the 2020 Gladiator User Guide (owner's manual) recommends inspecting the engine air filter at every oil change; part number 33-5076 (UPC 0 24844 36799 0) from O'Reilly or by searching online for "K&N 33-5076"

Note: Based on the findings of some experienced members of this forum, an oiled reusable engine air filter may not be the right choice for a vehicle that is frequently taken off-road or otherwise exposed to dusty conditions on a regular basis​

4. Front differential fluid:

1. MOPAR 68378949AB MS-A0450 API GL-5 SAE 75W-85 Synthetic Gear & Axle Lubricant 1 quart; some dealers are out of stock on MOPAR 68378949AB until December 2025

2. AMSOIL Severe Gear 100% Synthetic Gear Lube API GL-5 SAE 75W-85; 100,000 mi (see notes on AMSOIL Severe Gear longevity below); contains friction modifiers for limited-slip (LS) applications; meets Chrysler GL-5 based specifications; backed by a limited liability warranty; 2020 Gladiator User Guide (owner's manual) recommends, starting with first inspection at 20,000 mi or 2 years (whichever comes first), inspecting differential fluid every 20,000 mi or 2 years, whichever comes first; for Severe Duty (including OFF-ROAD), replace fluid every 40,000 mi or 4 years, whichever comes first (see pp. 198 & 200 in owner's manual); also see my reply on differential/axle fluid service intervals; 1.09 qts required, rounds up to 2 qts; 1-quart size; product code SVLPK-EA from www.amsoil.com

- Recommendation on first differential service: Regardless of normal or severe use, have front & rear differentials serviced before 30,000 miles

AMSOIL recommends Severe Gear SAE 75W-85 100% Synthetic Gear Lube for not only the rear (LS) differential, but also the front (open) differential; the friction modifiers in this product will not harm the front differential

Notes on AMSOIL Severe Gear longevity:​

• For Normal Service use, longevity is 100,00 mi (see AMSOIL data sheet)
• For Severe Service use, including off-road use of a Light Truck, longevity is 50,000 mi (see AMSOIL data sheet); this is 25% higher than the off-road mileage service interval listed in the 2020 Gladiator owner's manual (see p. 200); there is no limit on duration listed on the data sheet
  • In a phone call with the AMSOIL technical team, they assured me, unequivocally, that "Heavy-Duty Off-Road" applies to Class A commercial vehicles used off-road, such as large dump trucks, and does not apply to a Jeep Gladiator
• See AMSOIL product data sheet for additional information on dusty or dirty conditions, and water contamination

Off-manual guidance:​

• SAE 75W-85 provides better fuel economy, but SAE 75W-140 offers greater durability; as a Dana Rebuild Specification, SAE 75W-140 may be used for both axles; also see items 4 & 9 in my post on Key Info

• See AMSOIL product data sheet for additional information on dusty or dirty conditions, and water contamination

Notes on trailer towing:​

1. Check the owner's manual, confirm your findings with the dealer, and check other posts on this forum for guidance on whether to use SAE 75W-140 in the rear differential
2. There are two separate references to rear differential fluid on p. 234 of the 2020 Gladiator owner's manual:
   1. SAE 75W-140 (API GL-5) is recommended for "Rear M200 Sales Code DRZ"
   2. SAE 75W-85 (API GL-5) is recommended for "Rear M220 Sales Codes DRE/DRF"
3. Rear differential fluid must be compliant with API GL-5 and should be compliant with material standard MS-A0450 (for lubricant, SAE 75W-85) or MS-8985 (for lubricant, SAE 75W-140)
4. If equipped with a Trac-Lok limited slip (LS) rear differential (see DRE/DRF in owner's manual), a friction modifier additive is required; the fluid for a Trac-Lok limited slip differential should be compliant with not only MS-A0450 or MS-8985, but also MS.10111 (for friction modifier)
5. An internal dealer spec sheet states: "If equipped with a Trailer Tow package use...SAE 75W-140"
6. For a subset of vehicles equipped with a Trailer Tow package, the internal dealer spec sheet is in direct conflict with guidance on Sales Codes DRE/DRF in the owner's manual
7. A related post on rear differential fluid and other drive train fluids does not completely settle the rear differential fluid grade debate, but it does offer evidence for both options:
   1. Use only SAE 75W-85 (for DRE/DRF): Follow the owner's manual as specified
   2. Use SAE 75W-140 for trailer towing or in rebuild: Also consider dealer service data from Dealer Tech Authority (same as internal dealer spec sheet) and OEM supplier rebuild guidelines from DANA

• Conclusion on rear differential fluid grade for trailer towing:
  • With multiple points of documented guidance and expert opinion, SAE 75W-140 may be used during a service interval in which frequent trailer towing occurs
  • Due diligence: Confirm decision with dealer, change fluid on accelerated (heavy-duty/severe use) basis, and inspect metal shavings/debris at each fluid change
  • As the thicker grade, SAE 75W-140 increases protection and decreases fuel economy
  • If little or no trailer towing is expected after next fluid change, switch back to default grade of SAE 75W-85 (see DRE/DRF on p. 234 of 2020 Gladiator owner's manual)
• Product info: AMSOIL Severe Gear 100% Synthetic Gear Lube API GL-5 SAE 75W-140; other details on Severe Gear, including full compliance with material standards, also apply to this grade; product code SVOPK-EA from www.amsoil.com

Off-manual guidance:​

• SAE 75W-85 provides better fuel economy, but SAE 75W-140 offers greater durability; as a Dana Rebuild Specification, SAE 75W-140 may be used for both axles; also see items 4 & 9 in my post on Key Info

10. Transfer case fluid:

1. MOPAR 68218057AC MS-9602 ATF+4 Synthetic Automatic Transmission Fluid; 2020 Gladiator User Guide (owner's manual) recommends, starting with first inspection at 30,000 mi or 3 years (whichever comes first), inspecting, and replacing if necessary, transfer case fluid every 60,000 mi or 6 years, whichever comes first; 1.69 or 1.86 qts required, rounds up to 2 qts; 1-quart size from dealer or MOPAR eStore

Note on Severe Duty: For vehicles used for TRAILER TOWING or subject to long periods of idling or low RPM, change transfer case fluid every 60,000 mi or 6 years, whichever comes first, and inspect transfer case fluid every 30,000 mi or 3 years, whichever comes first (see pp. 198 & 200 in 2020 Gladiator owner's manual)​

2. Valvoline ATF+4 Full Synthetic Automatic Transmission Fluid; MS-9602; for the warranty statement, see section 1.9 in my post on Warranty Coverage; 2020 Gladiator User Guide (owner's manual) recommends, starting with first inspection at 30,000 mi or 3 years (whichever comes first), inspecting, and replacing if necessary, transfer case fluid every 60,000 mi or 6 years, whichever comes first; 1.69 or 1.86 qts required, rounds up to 2 qts; 1-quart size; part number 822348 (UPC 0 74130 00346 0) from Walmart

Note on Severe Duty: For vehicles used for TRAILER TOWING or subject to long periods of idling or low RPM, change transfer case fluid every 60,000 mi or 6 years, whichever comes first, and inspect transfer case fluid every 30,000 mi or 3 years, whichever comes first (see pp. 198 & 200 in 2020 Gladiator owner's manual)​

11. Transmission fluid:

Automatic Transmission

Fluid equivalence: Failure to use the correct fluid may affect the function or performance of your transmission
Fluid capacity: 9.5 qts, rounds up to 10 qts; pan drop requires 6 or 7 quarts; transmission flush requires 17 quarts, but a flush is not recommended after many miles because varnish may be present
Material standard: For MOPAR 68218925AB, the MS-number is not listed on the label or on the MOPAR eStore, but "8 & 9 Speed ATF" and "ZF" are shown on the front and back labels, and this MOPAR part number has been confirmed by more than one dealer

Longevity limit: ZF recommends changing the fluid for its automatic transmissions every 93,000 mi, or sooner when 1) operated under high temperatures, 2) subjected to heavy loads, or 3) past vehicle use is unknown, as noted on the first page of the ZF product data sheet (see doc #2 in ATF Equivalents); "OFF-ROAD" is not specified​

Note: According to an informal survey of service managers at a major chain of dealerships, changing the fluid for the automatic transmission oneself (DIY) will void the warranty

Summary of Lubricant Options for Chrysler 850RE Automatic Transmission in Jeep Gladiator

1. MOPAR 68218925AB: Jeep requires the use of "ZF MOPAR 8 & 9 Speed ATF Automatic Transmission Fluid or equivalent" to MOPAR 68218925AB; 1-quart size from dealer or MOPAR eStore
2. ZF LifeguardFluid 9 (ZF No. AA01.500.001): MOPAR 68218925AB is a ZF-approved equivalent (see doc #1 in ATF Equivalents) to ZF LifeguardFluid 9 (ZF No. AA01.500.001); 1-liter size from www.fcpeuro.com
3. ZF LifeguardFluid 8 (ZF No. S671 090 312): The ZF-approved (see doc #1 in ATF Equivalents) and ZF-branded lubricant for the ZF 8HP50 / Chrysler 850RE automatic transmission is ZF LifeguardFluid 8 (ZF No. S671 090 312); 1-liter size from www.fcpeuro.com
4. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid (product code ATLPK-EA): The AMSOIL equivalent to MOPAR 68218925AB is AMSOIL product code ATLPK-EA (no ZF approval number, see Notes on claimed equivalents in this section below); 1-quart size from www.amsoil.com

Also see the table in section 1.10.1 of my post on Links to Prices

The key details of the following two sections are included in the summary above

ZF-Approved Lubricants

The Chrysler Torqueflite 850RE automatic transmission, manufactured by Chrysler under license from ZF, is based on the design of the ZF 8HP50.

1. Transmission manufacturer-to-lubricant conversion:
Chrysler 850RE = ZF 8HP50
ZF 8HP50 (see doc #1 in ATF Equivalents) = ZF LifeguardFluid 8 (ZF No. S671 090 312), (ZF approval number ZF000020)

2. MOPAR-to-ZF lubricant conversion:
Stellantis Oil No. 68218925AB (see doc #1 in ATF Equivalents) = ZF LifeguardFluid 9 (ZF No. AA01.500.001), (ZF approval number ZF005946)

For reference only: Chrysler Oil No. 68157995AA = ZF LifeguardFluid 8 (ZF No. S671 090 312), (ZF approval number ZF000020); 68157995AA is NOT SPECIFIED in the Gladiator owner's manual​

Lubricants with No ZF Approval

1. AMSOIL-to-MOPAR lubricant conversion:
AMSOIL product code ATLPK-EA (no ZF approval number) = MOPAR 68218925AB

Notes on claimed equivalents:​

• Depending on the consumer protection laws in your country, the use of a claimed equivalent fluid can void a warranty
• Definition of claimed equivalent: An aftermarket fluid that its manufacturer claims is a part-to-part equivalent to the OEM original, but is not published on the list of approved equivalents managed by the approver of the compliance
• In the case of ATF for the Chrysler 850RE automatic transmission, a claimed equivalent is a fluid that is not approved by ZF; ZF owns the formula and approves the compliance (see doc #1 in ATF Equivalents)
• AMSOIL product code ATLPK-EA is a claimed equivalent (no ZF approval number)
• Depending on the consumer protection laws in your country, consider using a claimed equivalent only after the warranty has expired

Transmission Talk

Rumors & hearsay: Be aware that some Jeep service advisors still insist (as of December 2024) that the original automatic transmission fluid in this vehicle is a "lifetime fluid"; the original advice on this topic was provided in response to a question about why "automatic transmission" is not mentioned in the Scheduled Servicing section (pp. 196-200) of the 2020 Gladiator User Guide (owner's manual)

Speculation vs. data sheet: There are also some who speculate that the longevity of this fluid exceeds the end point of the service schedule in the owner's manual; the ZF product data sheet (see doc #2 in ATF Equivalents) is a much better basis for determining the longevity of this fluid; be aware that SEVERE, HEAVY-DUTY, or OFF-ROAD service use can significantly reduce the longevity of a transmission fluid
See discussion of "lifetime" automatic transmission fluid on this forum

Manual Transmission

1. MOPAR 68218057AC MS-9602 ATF+4 Synthetic Automatic Transmission Fluid; 2020 Gladiator User Guide (owner's manual) recommends, starting with first inspection at 30,000 mi or 3 years (whichever comes first), inspecting, and replacing if necessary, manual transmission fluid every 60,000 mi or 6 years, whichever comes first; 2.38 qts required, rounds up to 3 qts; 1-qt size from dealer or MOPAR eStore

Note: The service intervals for normal driving are borrowed from the Transfer Case section (and are equal to twice those of SEVERE use) because, for Manual Transmission, the owner's manual only lists service intervals for SEVERE use ​

Longevity limit for SEVERE, HEAVY-DUTY, or OFF-ROAD service use: 30,000 mi or 3 years, whichever comes first (see p. 199 of 2020 Gladiator owner's manual); SEVERE service use includes, but is not limited to, when more than 50% of driving is at sustained high speeds in temperatures above 90°F​

Note: The Gladiator owner's manual (see doc #5 in my post on ZF docs and advice on ATF from the owner's manual) states that, for normal driving, ATF for the manual transmission will last for the "life of the vehicle"; however, I have chosen not to change the (derived) service interval for normal driving (shown above) because the lifetime fluid statement is highly debatable; before changing manual transmission fluid, thoroughly investigate required steps to be taken before & after changing fluid​

2. Valvoline ATF+4 Full Synthetic Automatic Transmission Fluid; MS-9602; for the warranty statement, see section 1.9 in my post on Warranty Coverage; 2020 Gladiator User Guide (owner's manual) recommends, starting with first inspection at 30,000 mi or 3 years (whichever comes first), inspecting, and replacing if necessary, manual transmission fluid every 60,000 mi or 6 years, whichever comes first; 2.38 qts required, rounds up to 3 qts; 1-quart size; part number 822348 (UPC 0 74130 00346 0) from Walmart

Longevity limit for SEVERE, HEAVY-DUTY, or OFF-ROAD service use: 30,000 mi or 3 years, whichever comes first (see p. 199 of 2020 Gladiator owner's manual); SEVERE service use includes, but is not limited to, when more than 50% of driving is at sustained high speeds in temperatures above 90°F​

Note: The Gladiator owner's manual (see doc #5 in my post on ZF docs and advice on ATF from the owner's manual) states that, for normal driving, ATF for the manual transmission will last for the "life of the vehicle"; however, I have chosen not to change the (derived) service interval for normal driving (shown above) because the lifetime fluid statement is highly debatable; before changing manual transmission fluid, thoroughly investigate required steps to be taken before & after changing fluid​

For additional details on an automatic transmission or a manual transmission, please search for other posts on this forum or check with your dealer

12. Transmission oil filter:

1. MOPAR 68417054AB Transmission Oil Filter; from dealer or MOPAR eStore

Note: See longevity limit on transmission fluid for automatic transmission, in transmission fluid section, above​

Where to Buy

Walmart is inexpensive, major auto parts chains are convenient, Summit Racing has a wide selection of high quality products under various brands, AMSOIL has a wide selection of high quality products under its own brand, the MOPAR eStore is the official MOPAR online store, and site sponsors are listed here​

​

Tip: If the price at the dealer is higher than the price on the MOPAR eStore (or even if it is the same), ask "Is that your best price?"; a parts advisor should have the authority to adjust the price, and asking for a lower price is not an insult​

Create Your Own Fluid & Filter Lineup

- To do this the easy way, skip to #17 below

Document the details:

1. Until you document the details, save the container and packaging​

2. Document part numbers, material standards, industry standards, capacity, longevity, and service intervals; as you use tools, also document required tools and torque specifications​

3. For aftermarket products, also document the 12-digit UPC (universal product code)​

4. Confirm material standards, industry standards, capacity, service intervals, and longevity limits in your owner's manual​

5. Confirm capacity for fluids using this internal dealer spec sheet (nominal refill capacities) or on www.amsoil.com (maintenance capacity may vary from nominal refill capacity)​

Vehicle warranty:

6. Be aware of vehicle warranty limitations; some warranties do not allow you to change the oil & filter yourself​

7. If you are not allowed to change the oil & filter yourself, you should be able to "bring your own" oil & filter to any qualified automotive repair shop​

Buy each product (or take photos of front & back labels):

8. Buy motor oil & filter from Walmart or an auto parts store (Mobil 1 Extended Performance Advanced Full Synthetic Motor Oil, and Mobil 1 Extended Performance Oil Filter)​

9. Buy differential fluid from AMSOIL (AMSOIL Severe Gear 100% Synthetic Gear Lube)​

10. Go to a dealer and give the parts guy your VIN; this ensures that you get exactly what you need​

11. Buy one of each of the following fluids & filters from the dealer: Engine air filter, cabin air filter, transfer case fluid, brake fluid, power steering fluid, and radiator fluid (antifreeze / coolant)​

Other resources:

12. Research part numbers on MOPAR eStore and Google (but be skeptical of results)​

13. Call multiple dealers to confirm a part number if you can't find a 100% clear answer​

14. Talk to knowledgeable employees at auto parts stores​

15. If you get stuck, call the manufacturer of a product​

Cheat-sheet:

16. If it works for you, copy and paste the fluid & filter lineup above into your own text file and change the information to match the fluids & filters for your vehicle​

17. Check out A) the two attachments at the end of my post on Key Info and B) the lists of prescreened fluid & filter options in my post on Links to Prices​

Fluid & Filter Series of Posts on Jeep Gladiator​

This post is a collection of links to my articles on fluids & filters for a Jeep Gladiator​

Sponsored

 

[The Lorax]

David, what a great and exhaustive dive into the fluid and filter requirements for your vehicle. Any idea if these requirements would be the same for a 2021 Mojave with 3.6

 

[g2020]

Jay, thanks for your feedback. I have added part number indexes and a section on creating your own fluid & filter lineup. This should simplify the process of verifying part numbers for a Gladiator of a later model year or a higher trim level.

As you know, the 2020 Gladiator Sport is the first model year and the base trim level. It will be interesting to see which fluid & filter specifications are different for other JTs.

Update on December 5, 2024:

The short answer is yes: All Gladiators from the factory, for all trim levels and model years, use the same fluids & filters. I went through the list with the parts guy at my local dealership today. There are some exceptions.

For more details, please see the (consecutive) sections called Fluid & filter uniformity and Summary of fluids & filters in this post, above.

The MOPAR part number for each fluid or filter listed in the summary, except motor oil, can be found in the Part Number Indexes (same list sorted three different ways), also in this post.

Have you bothered to read around the rest of the forum first?
Pretty much anyone here knows about the first model year and trim levels.
Fluid and filter specs won't change - why would they?

All anyone needs to do is RTFM - read the OWNERS MANUAL.
It's all in there in simple, concise charts - no scrolling around.
And for part numbers and fluid details, it's spelled out all over the place, and we can contact Benny here and he's got all of the part numbers for anything you would ever need for Jeeps of all sorts/kinds.

 

[Hootbro]

That is an orgy of information but a bit discombobulated.

 

[g2020]

That is an orgy of information but a bit discombobulated.

Here is some insight into how the content in this post is organized and formatted.

Presentation order:
- Filters are listed first so they don't get lost in the wash
- Oil & filter (as a pair), the most frequent job, is listed next
- Remaining fluids are listed by service frequency, from highest to lowest
- Transmission fluid is listed last because some people will only have this job done by a dealer / at a shop
UPDATE on 2024-11-24:
- The individual fluid & filter sections are in alphabetical order and numbered for easier reference

The part number indexes are limited to OEM parts, plus the first aftermarket oil & filter options, to keep the lists simple. Other aftermarket options can be found in each individual section.

Punctuation is used sparingly because key info from front & back labels, condensed to a few lines of text, is not not easy to review quickly no matter how it is presented. That is, unless one's focus is on an individual job, in which case punctuation is unnecessary because the scope is reduced from the entire post to a single section/job. Some first-time Gladiator owners don't know what OAT in antifreeze means. However, if they are focused on a single job / fluid change and see OAT in a series of terms, they will know that it is important and that it needs to match up.

For this type of content, I prefer text instead of tables, charts, or pictures because text is universally compatible and easy to copy & paste to a local file for editing and/or offline use.

Finally (for the nitty-gritty details), this is, in general, how the product details in each fluid or filter section are listed:

OEM product: Lead with MOPAR part number, and end with size & where to buy
Aftermarket product: Lead with manufacturer, brand, & product description, and end with size, part number, UPC, & where to buy
For every product: Manufacturer specification, industry standards, longevity, warranty, and capacity are listed (in order) between the lead info and the end info; some additional info, such as service interval, is also listed

However, if they are focused on a single job / fluid change and see OAT in a series of terms, they will know that it is important and that it needs to match up.

For this type of content, I prefer text instead of tables, charts, or pictures because text is universally compatible and easy to copy & paste to a local file for editing and/or offline use.

Finally (for the nitty-gritty details), this is, in general, how the product details in each fluid or filter section are listed:

OEM product: Lead with MOPAR part number, and end with size & where to buy
Aftermarket product: Lead with manufacturer, brand, & product description, and end with size, part number, UPC, & where to buy
For every product: Manufacturer specification, industry standards, longevity, warranty, and capacity are listed (in order) between the lead info and the end info; some additional info, such as service interval, is also listed

Google can extract text from images.........

For me, with severe ADHD, I'm a "give me a chart I can keep in my files, I don't want to pick out of text what's important". That flies in the face of what people like me DO, but it's a scientific/medical fact, the charts are much easier.
(that's why BOOKS like the owners manual uses simple charts and doesn't mix it in with the text of the book.)

Some first-time Gladiator owners don't know what OAT in antifreeze means

They don't need to know what it means! All they need to know is the word, so when they go shopping, they can look for the word OAT on the bottle/jug.
Really pretty simple. That's why in several posts here when someone has not read the owners manual - and asks "what coolant should I use - the answer is extremely easy to say and remember for that first time Jeep owner - OAT.
That's all you need to know or remember.
OAT.
They don't need to understand what it means or why, other than "don't mix coolant types - it might gel up on you". If they need or desire to know what OAT coolant is - go to google, and type in "OAT coolant". two words.

if they want an explanation, they'll ask.
(I guess some of this is the old-time "teacher's assistant" in me from decades ago. I used to write training articles on tech stuff for non-tech people, and did online support for Symantec in the 1990s)

Punctuation is used sparingly because key info from front & back labels, condensed to a few lines of text, is not not easy to review quickly no matter how it is presented. That is, unless one's focus is on an individual job, in which case punctuation is unnecessary because the scope is reduced from the entire post to a single section/job.

Wow - I disagree. You can use bullet points to point out key info from labels.
Worse, punctuation can totally change the meaning, and lack of, can lead to a long and confusing read. It's critical at times. Long, run-on sentences are hard to follow without it.
A recent quote raised an uproar, and someone said a piece of punctuation was left out. I won't go farther because it gets people banned (no, I'm referring to something said years ago, not this past month)

- Transmission fluid is listed last because some people will only have this job done by a dealer / at a shop

You can say that about axles, engines and other parts as well. Majority of all Jeep owners have the dealer do service work while in warranty, and then, most even beyond that. But then, in forums, that gets changed around as many forum members are seeking how to do things themselves........ one reason to be here.

But I go back to - RTFM.
Everything that's important is in the book.
If you don't have a paper copy, you can download a PDF online. The PDF is searchable. I leave a copy open in a tab on my FoxIt PDF app much of the time. It's also handy if someone asks about capacities or fluid specs and hasn't gone to the book. I can do the search, take a snippet and post it.

I guess in other words, much of the above is redundant, and is all over the forum in various places as well as the "book" that every Jeep owner has full access to - either in print or PDF. It's easier to have the PDF and search it than dig things up in a forum, IMO.

Here is some insight into how the content in this post is organized and formatted.

Presentation order:
- Filters are listed first so they don't get lost in the wash
- Oil & filter (as a pair), the most frequent job, is listed next
- Remaining fluids are listed by service frequency, from highest to lowest
- Transmission fluid is listed last because some people will only have this job done by a dealer / at a shop
UPDATE on 2024-11-24:
- The individual fluid & filter sections are in alphabetical order and numbered for easier reference

The part number indexes are limited to OEM parts, plus the first aftermarket oil & filter options, to keep the lists simple. Other aftermarket options can be found in each individual section.

Update on this post from the writer:

1. Content flow: Adjusted format to improve the content flow
2. Presentation order: Placed individual fluid & filter sections in alphabetical order, numbered all sections, and added summaries to make it easier to find a specific fluid, filter, or component
3. Service interval & longevity coverage: Included manufacturer guidance on service intervals and longevity, for severe/heavy-duty/off-road use, for each fluid or filter
4. Experienced member guidance: Added guidance on being wary of an oiled reusable engine air filter, especially for off-road use
5. Other key content: Added other important content such as fluid equivalents for the automatic transmission
