I will recheck with them.
Thanx for the heads up before I make a mistake.
I know for the next 3K its running the factory oil as they changed it.
2015 Jeep Wrangler JKU "Tank" Sport S
2002 Avalanche: To many mods to list
Just changed my oil for the second time, now at 5000miles. Yes that's right you anti-change early freaks two changes in 5k. Still found some metal in the filter but that could have been there since 1001 miles. anyway my OCD is satisfied and that's all that really matters.

But there are certainly other top notch synthetics or even conventional oils that will suit your needs that are certified under MS6395.
Mobil 1 5W-20 synthetic motor oil meets or exceeds the requirements of:
API SN, SM, SL, SJ
It has the following builder approvals:
General Motors Service Fill dexos1™
According to ExxonMobil, Mobil 1 5W-20 is of the following quality level:
General Motors GM 6094M
I believe in running a vehicle hard (after warming up) for the first 100 miles then changing the oil to break it in. That is what I was taught. It doesn't make it right...I think following the book is fine.
Building out a Jeep is like trying to smother a fire with twenty-dollar bills. You just never have enough at once to put it out...

Mobil 1 does not meet MS 6395 because of a ridiculously long field testing phase that Chrysler requires to meet the spec. Mobil is without a doubt a fine oil that will work well in any and all vehicles. If you email the folks at Mobil 1 they will tell you that they believe the oil exceeds the specification, but it has not yet been approved by Chrysler and has not yet undergone the required field testing to please Chrysler. I would be hesitant to use it simply because someone at Chrysler could reject an engine warranty claim due to "non approved" oil being used. It is a bunch of BS, but until the Mobil 1 bottle has that 6395 sticker on it, I'd be hesitant to use it.
