can the 87 octane with 10% ethanol be used in my 1.8l, turbo 225 bhp 2001 audi tt roadster
no- buy the highest octane gas you can find- why do you even think about cheap gas with corn? That's an expensive, high performance car- and the engine and turbo are gettin' old
More or less what the last guy said. If you use cheap gas even with a octane booster all you will do is gum up your fuel system and get crappy millage out of your car.
