    Marketing BS. All directed at keeping the consumer confused. The simplest recommendation for all vehicle owners is to use whatever the OEM suggests.

    And Mobil1's website still does not recommend any of their oil products for my 2015 Challenger SRT 392.

    They do now recommend their 0W-20 and 5W-20 products for my 2017 Durango R/T 345 ... while acknowledging that it doesn't have approval from Dodge (or Ford for that matter, just GM.) They didn't use to recommend any product for that vehicle.

    I'm not saying Mobil1 is a bad oil. I use it in my 2005 Chevrolet Monte Carlo LS (3.4L V6) and used it in all of my GM vehicles from at least the early '90s until 2013 when I sold my 2005 Pontiac GTO. I also used it in my 2011 Challenger R/T Classic when I first bought it in 2013 before switching to Pennzoil.


    BTW ... One of the exclusions in Mobil's Warranty that you linked to is:
    • Situations where the OEM required lubricant standards do not match those stated by ExxonMobil without written approval from ExxonMobil.
    So, unless you get written approval from ExxonMobil to use Mobil1 in your SRT (6.1 or 6.4,) they're not obilgated to cover you for any repairs while using their oil. For what it's worth ... Valvoline put a warranty in writing for my buddy who wanted to use Valvoline Full Synthetic in his 2018 Challenger SRT 392.

    Mobil 1 0W-40 was specified for the 6.1 Hemi engine. It is even printed on my oil fill cap.

    That could have easily been the cap for my 2005 Pontiac GTO.

    Hey ... you're out of warranty so you're free to use whatever you want. But just know that Mobil1 no longer recommends any of their oils for the 6.1L/372ci engine. I don't know why. Maybe something changed in how they formulate their oil.

    And folks that are still under their powertrain warranty should stick to what's in their new car manual ... Mopar, Shell, or Pennzoil ... in the correct viscosity for their vehicle.

    Here is a recent response from a Mobil 1 representative about this certification issue.

    ""At the moment, we do not have any word on when we might have a FCA approved 0W-40. Unlike MS-6395 which covers most of Fiat Chrysler's gas engines FCA has at least 3 different 0W-40 specs in recent use. SAE 0W-40 already represents a small percentage of FCA power trains, and when they subdivide it into 3 yet smaller bites, it's hard for any motor oil manufacturer to decide which to pursue first. Conceivably there might be one so small that no one expects to make their money back on developing a new formulation.

    I suspect one of the biggest favors FCA could do for customers in platforms requiring 0W-40 would be to create a new single Material Standard which combines and supersedes the current specs. GM did this in 2011 when they introduced the Dexos program, eliminating 7 or 8 different GM specs on a global scale."

    Thanks for the update.

    Kudos to Mobil 1 to acknowledge that they don’t have an oil that meets the specs for the SRT engines at present.

    And that’s a little surprising since the specs have been in place and stable since at least 2014.

    Not really, lol, although I have bought a lot of Mobil 1. Mobil 1 0W-40 was recommended by Dodge for my 6.1 Hemi. It lubricates great and I never had the Hemi tick, so why change?
