Hi guys. Recently my MPG has seemed to get worse. I put this down to constantly running under full operating temperature (due to a dodgy stat), but after replacing it, it still hasn't improved fuel economy. Last week I put £60 worth of v-power in it. I've since done 105 miles and it's just hit the half way mark. Surely a stage 1 A3 should be getting more than 210 miles from a full tank?! I don't really drive like a nutter and never take it above 3k rpm until it's at 90 degrees. During my last MOT, I was advised that the "fuel filter looked soggy and smells of fuel". Could this be the cause? Suggestions?
