I talked to an Amsoil Agent and I was told the Amsoil Euro FS 5w-40 meets the 12-991. Chrysler oil specs
I use it. I’ve been using Amsoil since 2006.
So 10K on the wrong oil. Looks like you're our experimental subject.I've had 3 oil changes on mine (every 5k) so far, All were done at the dealership since they were free.
The previous two times the dealership used Rottella. Today they said they were not allowed to use rottella and used mopar oil.
a Jeep Grand CherokeeJust had first oil change done at dealership, they were going to put rottella in but due to you guys here I was loaded for bear, without a fuss they used Penn Utra full syn after I read the owners manual to them and showed them the list of approved oils found here!
Thanks. Also I’m kinda slow on stuff, what is wk/2 engine?
