i get 450Km MAX on a full tank driving like a grandma if I drive how I like to, about 380-400 using 98 octane fuel aswel!. r33 gose worse on the hiway because it revs about 3000rpm when going 110kmh or maybe its just my car i hope not. but still I'd still rather pay that $20-$30 a week more on fuel to drive my car then a barina or some shit. and my car is pretty stock nothing that sucks more fuel just stuff thats meant to lower fuel consumption exhaust,intercooler,splitfire coilpacks,airfilter.
