I find Optimax kind of "goes off". I know the C900 T16 crowd highly recommend it, but finding a C900 T8 pilot who rates it is pretty rare. If it works for you, great ... Go with it. Seems like the 16V engines are okay with it. I run it through about 1 in 10 tanks, rather than one of those injector cleaner products. Our FIAT loves it ... Well, the fuel was engineered for Ferrari :) Paul 1989 900 Turbo S
