I know there are a lot of folks on the site that don't really care about the GM recommendations, but I just want to maintain my V and not be denied a warranty claim (if needed). I also don't want to start an oil war, but I have been trying to determine what the current from GM recommendations are for fluids...mainly engine, trans, and diff oil.
Differential:
The original recommendation for differential oil required the addition of a 4 oz bottle of friction modifiers. Then, the Dexron LS gear lube came along (GM P/N 88862624) and does not require the additional friction modifiers. Is Dexron LS still the current recommended lube for the differential?
Engine:
I know we all will agree that Mobil 1 is the best oil on the planet and that is why Cadillac uses it :duck: Is an oil that meets the GM spec 4718M still the latest spec requirement, is there a newer spec, or is dexos1™ the new requirement?
Transmission:
For an auto...Dexron 6. Still the latest recommendation?
Anyone else think that a sticky (updated when needed) on the latest recommended fluids would be helpful? Does GM have a link that lists their current recommendations?
