What do ya think good bad average fora 59 plate couldn't say what stage cobb if any ????
What is near empty though? How many litres did you squeeze back into the thing on fill up? 74 litre fuel tank so 16.28g
325/16.28 = 19.96mpg
If you only managed to squeeze 60-65litres back into the thing then it clearly wasn't empty. Your empty and my empty may be totally different things
