To be fair last night i renewed my Thermo & Temp sender and my MPG is amazing, for example, I drove home today 8 miles and pushed the car quiet hard (when i could and it was safe) to be honest I really wasnt paying attenion to my fuel/mpg the reason behind this is because before i replaced my therm/temp if I pushed the car hard e.g took gears to 4-5 RPM then when i stopped at the lights I found my tick over was all over the place, lumpy idel and the car would sometime struggle to not cut out, but today I got none of that and while sitting at the lights twice, im not even joking I thought id cut out because my car was so quiet and smooth running

anyho the point to this story is when I got home I checked my MPG and it was sat on 32MPG even after a hard drive, and my engine is on 118k, however shes well looked after, recently hard a Full major service inc Belt/Water pump, thermo, temp sender, new plugs, new filters, new oil, new coolent, new DV, New MAF:)
I should also mention Im using a pippercros pannel filter but without the smooth air box.
Hope this helps
