Stock. $10 at Walmart.Filter recommendations?
Most manuals say "recommend". It's the same with Subaru, but I can tell you that they will void the shit out of your warranty!The owners manual says “ we recommend....” not “we require...” so what you use is up to you. Any lubrication issues when using a different oil would be on you.
Having said that I can guarantee that no one on this forum has a PhD in Chemical Engineering and has more experience than the guys who designed the 3.6 so why try to second guess them..??
Driving your Jeep in South Florida does not put a great thermal stress on the truck. Most manufacturers test their vehicles in places like Australia in the summer where temps can run over 120 degrees and Alaska in the winter when it’s 30 below...
The above information plus the fact that the first 4 changes are free at the dealer makes it a no brainer for me...
Just my $0.02
How about EVOO?Coconut oil is a favorite of mine. Smells amazing on a warm engine
I’ve traveled down this rabbit hole with German, Brit and Japanese autos and assorted motorcycles over the years. The information can give you a migraine. Oil has come a long way. Metallurgy has come a long way and can be fickle in some applications. Machine tolerance is much more precise as well. I had to force myself to not pour 10w30 in things based on what worked well for me on my first car. Use the recommended weight, pick your favorite brand, change your oil on schedule, and monitor wear. Most high end oil will do what is required for the interval. If you are in an extremely demanding situation, change more often. Peanut oil smells amazing too.
I’ll check that one outHow about EVOO?
CAFE 100%. I've been a long time Ram and Hemi owner. It's pretty common issue for lifter tick and cam failure on 5.7 Hemi's. One of the thing we/I have been doing for years is going from the recommended 5w20 to a 5w30 or even 0w40 oil with high moly content. Redline, Amsoil, Pennzoil Ultra Platinum. All high moly content oils. We're not seeing any issues with VVT or the MDS systems using higher weight oils. But the tick either goes away or subsides considerably. And lifter/cam failures aren't as frequent.0w20‘s primary reason for existence is cafe for sure. And of course they bend to the will of the government...they dont have a choice. The government is hung like a clydesdale and thinks saying “bite the pillow. Im coming in dry” counts for foreplay.
i have some education in chemical engineering and applied physics. Going to a lighter oil doesnt necessarily mean it isnt protecting The engine. Modern oils stand up way better to heat and sheet than they used to. And modern machining tolerances -even on aged motor designs- means less issues in surface wear to parts.
believe me, i get it. Years ago i ran 20w50 in my track car. It took me a long time to come around on 0w20. But good 0w20’s are some of the most engineered and tested oils ever made; and the aversion to them is normalcy bias on what we have been used to.
I've switched to synthetic media filters for my performance stuff. What got me started was the fact that I was finding it impossible to find filters locally for my Javelins. And there's a VERY close proximity as far as oil filter to the output terminal on the alternator, and the oil pressure sending unit and if like me you run both a light and a gauge (rally pack) it's even worse, a full sized filter was a pain.. And a synthetic glass fiber media filter.
This is my plan. I’m close to 40k on the clock & just ordered Amsoil 5w30syn. Have been running Amsoil 0w20syn since 1st oil change @ ~5k.You would be better off using the lighter weight oil for the first 30k. The tolerances are much tighter at this point and that is why the oil spec is 0W20.As the engine wears then go to 5W30
Ill file this in the "wont make a bit of difference" column ...This is my plan. I’m close to 40k on the clock & just ordered Amsoil 5w30syn. Have been running Amsoil 0w20syn since 1st oil change @ ~5k.

And honestly, I swear i'm not being difficult but seriously, aren't we overthinking this ? Tolerances are tighter and THAT is the reason for the 0w20 ? So, which is it ? Is is a government thing ? Is it a CAFE thing ? Is it a tolerances thing ?
Based on this I guess we should be switching to 10w40 at 80,000 when tolerances are looser still ?
At what mileage should I plan to switch to 20w50 ?
Run the recommended weight. I guarantee that you will not have a problem caused by lubrication and I am confident in this statement because i've never seen nor heard of one that was due to the oil specifically ... Or run 5w30 and you wont either ... The engine will last the same number of miles which will occur 3 owners in the future ...
Honestly this stuff has me perplexed ... A new reason based on science with no science to back it up ... And by science, I mean measurements and documentation ..
Flame away ...
If I've been too sharp here, I owe someone a beer ... Im really a nice person ...
LOL - too much speculation. Over-thinking. Non-engine builders making it complex.Ill file this in the "wont make a bit of difference" column ...
