I'm getting very poor gas mileage, about 400KM per tank, 50Litre tank(sorry don't know the conversion to miles) 8km/L. Not too good. My fuel filter & plugs are less than a year old, wires fine, tire pressure good, all the basic tune-up parts good, do regular oil changes (4000km) with synthetic. Can't figure out what the hell's going on. I'm thinking fuel pump, don't want to pay the $ to fix it and not technically inclined enough to do it myself. Any other things it might be? Please help....gas ain't cheap anymore ya know!!
