Both are Dexos 1 Gen 2, why have the same thing done so different?
Valvoline is pushing the VME as a solution to carbon buildup in DI engines, I guess how they actually do this is the big mystery.
Sometimes low SA oils (as VME seems to be) are considered to help limit overall deposits, but I don't know that they would necessarily have anything to do with carbon deposits in particular. The VME oils do not have extremely low NOACK losses (11-12%), so those wouldn't provide good low deposit arguments.
My only guess is that there is some special organic chemistry going on to help with the DI carbon deposit issue...???
I think you are on the right track. As I recall there were previous discussions regarding Synpower and the possibility of something added that a analysis cannot pick up. It’s the same with M1 AP. The voa we saw were “unimpressive “. I’m sure the base oil has all the answers.
I still think it’s overpriced unless Valvoline comes out and says it’s full of esters and pao. Even then, it should be $30 max.
