I have friends at work that own Ram trucks. When I ask them what oil they use they say, "I do not know, what ever Syn they use at the dealership"
I want to use the best I can easily get but at this point I have no idea.
AmsOil has cool test that show they are they best on 4 out of 6 test they do buts its the Signature Series but its not API certified, plus its seems like it will be hard to get with out ordering. Ram wants me to use API to honor warranty. By they Redline did poorly in AmsOil test.
Everyone I know that does not have a Ram uses Mobile-1 , but I read on here Ram owners say Mobile-1 makes the HEMI tick worse. I do not hear it yet and do not want to.
I was leaning toward AmsOil initially but not so sure how the API version XL holds up against other leading brands. Like to get the Signature Series seems like it is the leader in testing but not API certified.
I was sold on RP because lots of people love it and seems they have really good Syn Oil filters. But RP no longer has molly, ( looks like AmsOil 10k mile oil XL does not use it either and its supposedly better than the AmsOil OE oil that does).
Redline did poorly in AmsOil test (Supposedly independent test)
I am leaning to Castro Edge at this point
I welcome any thoughts because I do not know what to get at this point really.
