I was going to change the oil at 1,000 miles but dealer said I’d do harm. True or false?

[Gee Man]

If you are afraid of MIO, just pull the oil filter and look at it !

This is what happens when you let a TJ guy troll over here, lol!

Im an LJ guy originally so I understand. The ole 4.0 you could play with oil weights a bit. These new ones, the tolerances are way tighter so I’d be very leery of changing up oil weights. The 0w20 has worked well so far over 67k and from 13-110 degree weather so I’ll keep on running it. Granted, I’ve only put about 25k of those miles on there so hopefully the PO didn’t do anything too crazy when they had it.

Yep, the 4.0L on my TJ just keeps on a plugging away at 218K miles.

I'm sure you all know about the camshaft issues with the 3.6L. Thinking past the break in stuff, what are your thoughts with a preemptive strike by changing to 5W20, or even 5W30 after break in?

No

I personally follow an “extreme” version of oil changes for a brand new vehicle, based off of what Lake Speed Jr. does with his personal vehicles. If you don’t know who he is, he’s a tribologist (a specialist in the science of friction, wear, and lubrication), certified lubrication specialist, son of legendary NASCAR driver Lake Speed; owner of Speed Diagnostix, and runs the YouTube channel “The Motor Oil Geek.”

Using thousands of samples and data points from his oil testing company, he does the first change at 500 miles, then again at 1.5K, 3K, and then 5K. Then he changes every 5K after that.

I know many will say that’s absolute overkill, but if a dude who literally spends almost every minute of his adult life studying, testing, and developing engine oils says that’s what he ”knows” is best, I’m gonna go with that.

Lake also recommends not changing the filter during those initial changes since the filter becomes more efficient over time. I didn't have the guts to do that. I changed mine at 500, 2k, and will change again at 5k. I am sticking with 0w20.

OP, no changing your oil at 1000 miles for the first time will NOT hurt ANYTHING, besides your wallet for another oil change bill.

The synthetic oil is good for up to 1 year or 10k miles. I did the first change at 3k miles, then followed the oil life monitor down to 1% for the two free changes.

That's marketing BS. For over a decade, manufacturers have "designed" their engines to be allowed to consume all/more than all of the oil capacity within that 7.5-10k interval they advertise. I'm sorry but 1 quart every 1000 miles is NOT an acceptable consumption rate EVER. You're engine holds 5qts, but has a recommended 5000 mile OCI. Enjoy engine failure down the road (lease people couldn't care less).

THIS IS THEY WAY! This is how engine builders that know their product and how to build them to last break-in an engine. This is how I did my stroker in my rally car, my 636 and zx10r, and my 450 supermoto. They all made great power, never burned a drop of oil, and I beat the living piss out of those engines without failure.


If you want it to last, follow this guide for new engine break-in procedure. I've got 30,000+ RAPED APE miles on my stroker, I do 3k OCI's and the oil is still a light brown and Blackstone still can't find ANY wear or contaminants.

I just did mine at uh,uh , I cant remember ,I think 3,000 , heck I have 152,600 in it now .

You won't hurt anything.

On a new vehicle I usually change the factory fill 500-1000 miles, then change every 5K miles after.

On my Mojave I dumped the factory fill at 774 miles. Changed again at 1892 miles and filled with M1 ESP 0W-30.

Good man, and that's why it's still running so well.

Sorry, that 10K miles is not marketing BS. Modern synthetics can go that long with no issues. At least the quality oils can. I've gone many times over 7,000 miles and results come back "you could have gone farther". Oil chemistry and viscosity was fine, and wear metals not a problem.

Other than when I do an engine build, all of my factory engines have gone a couple thousand before the first change.

There's no reason other than personal preference for those short 3,000 oil change intervals. The engine won't last any longer or shorter. It's a feel good thing and nothing else. Even Lake himself said that the oil life monitor is VERY accurate. He's compared to actual oil tests. For some, such as myself, the OLM will hit 0% before 10,000 miles, closer to 8,000 miles - towing, shorter drives and so on - they are based on science.
It's a scare tactic to suggest anyone must or should change the oil so soon. It won't last longer, or last less miles. There's no reason to not change the first oil before 2,000 miles, no reason not to. There's more crap floating around about oil and changes than fact, even at the dealerships.

These oil threads and oil change interval threads always become a load of BS with all of the "it will be better with........." things. You can change the first oil at 100 miles if you want, or 5,000 and it won't matter much. Does anyone here actually think that the MAJORITY of all new vehicles sold get their oil changed before the first interval in the book? No. Many will go 5,000-10,000 on the first oil and each change after that. Forums are far far far from representative of what's REALY out there, and yet forums seem to believe they speak for majorities. Hardly, not even close.

I can't even begin to recall all of my cars and trucks that have gone over 100,000 miles, even 200,000 miles on original engines.

If you break engines in as I've outlined here for over 5 years, you won't have an issue - and break-in happens much faster than people believe. When I return a car to the owner after an engine rebuild, it is broken in and they can drive it in any way they wish, as long as they vary the RPM in the first miles.

Correct, and NO reason to not. I've gone over 7,000 on more than one occasion - the test results always come back "you could have gone longer". And hey - never lost an engine. Been at this since the 1970s, tons of experience building and repairing many hundreds of cars, lost track of all of the engines I've built and rebuilt over the decades. People who freak out over going more than 5,000 miles - it's a hoot, really.

 

[ShadowsPapa]

Jeep does not use a break-in oil. It's safe to change the oil whenever you want. Many owners do the first change at 500 or 1,000. I changed mine at 2,500 the first time and will go in 5,000 mile increments from now on, always with full synthetic.

Break-in oil is a MYTH - no auto maker in the US uses it. It's been a dead thing for decades. But people believe myths more than fact because they are REPEATED as fact all over the web.

Ask the people who changed and ended up having to replace cams. IGNORE most of the bull shit you see on forums.

 

[James H]

My only problem with bringing it into dealer for an oil change at 1k miles is that I'd be afraid they might simply tell you they changed it. But I worry about that stuff and that's why I change my own oil. I do wonder what I'm going to do when it's transmission time though because I'm not changing that fluid myself.

It's not nearly as bad as you think. There are a few YT videos detailing the steps involved, pretty straightforward process.
