Gas Mileage

[sergeA4]

everytime i fill up my tank(with premium gas) i only get about 420-450km, in the city,which is not that great, i thought i could get around 600 or so. Just wondering if its cause the car is too heavy for the engine, or some of my parts bad, or is there something else i could do to improve it

Yeah I get around 300-350 MILES on a tank here, and that's not even avoiding boost.


Maybe you should do a tune up, spark plugs, etc?
