Mobil 1 states that their 5w-30 is okay for 5w-20 applications. Check with Rage on a-tl to confirm this as well as he knows alot of about the subject.BozzTL-S said:I have hear that 5w-20 is a new oil that they made for those new vehicles.
The vehicle that recommended 5w-20 are not allowed to use other oil. it can used 5w-30 if you couldn't find 5w-20 but it must use 5w-20 when next oil change.![]()
