I've read around here that valvoline is pretty much considered a joke. Conversly, many, many, maaaaaaaaannnnnnnnnyyyyy people I race with or I know have raced have absolutely sworn by their racing oils. Now, I don't do really hardcore racing, just autocrossing, but I do it 20-30 times a year. I do use VR1 because it's cheap and it's been recommended by some of the folk that I either know race or I race with currently. My question is, is this really a good oil to use for this price range ($2 max)? Is there something else that I should, shouldn't be using? In addition to this, during the winter I use 10w30 Max life for when I do ice racing. It sees temps as low as -5 F, but is only started stone cold once the entire day. The car is an 85 Nissan 300zx that burns no oil. I Change my oil every 4 races in the summer and never change it during the winter (I put less then 1500 miles and I never see the rev limiter).
