The old oil compatibilty issue with E85.
From my understanding the "ester" base in the 300V oils is a big no no. Something to do with it breaking down with the alcohol in the ethanol fuels.
Some people say its fine... other people say it wont work... then you have clowns up at Autobarn saying that "no oil in Australia will tolerate E85.... Your car is going to turn into a bucket of mush as soon as you start running that crap"
When my car gets tuned I want to get a oil analysis done with Motul 300V 15W-50 (what I have always run in my GTR) and put this stupid yes, no, maybe, what if bullshit to bed!
