    Mobil 1 would exceed the 6395 spec. Many Chrysler/Jeep dealers fill customer vehicles with it on their premium oil changes, as does my dealer. The odds of them voiding a warranty claim over that issue are zero percent. Why? Because if it went to court, Mobil 1 would be subjected to their standard and it would easily exceed it. Mobil Super Synthetic is their bottom end oil and it meets the 6395 spec.

    Is there really much of a difference between Mobil1 EP and Pennzoil UP?

    Yes. Read the product data sheet. The Pennzoil is an outstanding oil and would far exceed what the Pentastar needs or requires, but it is a Group III oil, with base stock refined from crude oil and/or natural gas. Mobil 1 EP has Group IV or PAO synthetic base stock, which is a true synthetic that has properties that can't be duplicated by a Group III. Look at the flash point and the pour point. The Mobil 1 EP has a higher flash point and a lower pour point. It can handle much longer oil change intervals. That said, Pennzoil UP has some things in the additive pack that are excellent, too. You simply could not go wrong with either. If it makes you sleep better to have that MS-6395 stamp, then go with the Pennzoil and know you are running one of the best oils on the market.

    Any major brand of oil, and even some generics, like Wal Mart, are excellent oils and would do fine in the Pentastar, which again, is known for being pretty easy on oil, due to its lack of turbos and direct injection. I go with Mobil 1 mainly because I like the protection it offers at extremes that admittedly, I'll probably never encounter.

    Taken from jeepoffroadadventures. It's always gonna be about money.



    Why is Mobil-1 Not on MS-6395
    As mentioned, Mobil-1 was included in the MS-6395 certification (as well as MS-10725 for other Chrysler vehicles) and Mobil products used in factory fills. Mobil-1 was even printed on the oil filler caps for some of Chrysler’s automobiles. As early as February 2009 Chrysler started phasing out Mobil and started using Pennzoil for factory fills. One explanation for the change, is SOPUS (Shell Oil Products US), parent of Pennzoil, was brought in with the purchase of Chrysler by Fiat. The assumption is Fiat had an established and stronger relationship with SOPUS.

    MS-6395 Specification as of July-2012

    Others also say that switching to sn
    If you trust them, have at it. My dealers "oil change men" , not mechanics, forgot to put my oil fill cap back on my JL. I drove it for over a week like that! They left it in the front of engine bay. I didn't think to check behind them.

    Mine is, too, but I think it's the warmer weather as I only have 600 miles on the odo and no new oil. It suddenly got much better when the weather warmed a bit. It may be that the engine doesn't like the cold.

    I think in automatics the torque convertor clutch doesn't engage until the transmission fluid reaches normal operating temperature, which takes longer to happen in cold weather, so that could be it.

    Does the oil life reader actually measure/check anything about the oil? Or does it simply record the miles driven and/or hours driven to calculate the life of the oil?

    Mine has been climbing as well (no oil change yet). I'm around 600mi too. I think it has to do with a break-in period. I experienced the same with my 2014 Durango ... gas mileage improved between odo 500-600mi despite the fact that the temperature had dropped during that time.
