Interesting... I don't remember the exact math, but ethanol is something like 50% "thinner" than gasoline, so it leaks past the cylinder rings, mixes with the oil, then burns off and takes a bit of oil with it. This is an issue all alcohol powered cars, even street cars. It makes you wonder how economically and ecologically sound renewable fuels really are. A SBC/LS/LT, despite its displacement, is a very effecient race engine too.
I learned this from watching drag racing because drag racing is rad too.
