I have just bought (but not taken delvery) of an import 95 WRX - what difference does optimax make and how many miles do you think i could get to the gallon or a full tank?

ps what does all this MY00 / MY03 mean

cheers!

MY = Model Year, usually runs from August, I.e. a 1996 car built and in June 1996 is MY96, a 1996 car built after August 1996 is MY97

I would expect around 20-25 mpg if driven "normally", if on track or geberally "going for it", then expect anything from around 8mpg to 20mpg
