weird why the US have a different gallon measurement to UK.... all our fuel tanks are 80 litres. which is 17.6 UK gallons. I always fill up on 99ron juice. do you US guys have to put additives and octane boosters in your fuel tank every now and then, or are the ECUs set to allow for lower ron fuel?
