I am on my third 8 valver. I am very disappointed with the fuel consumption of my present car. Tankful can get me 350 miles, works out at best 34MPG and worst 30MPG. My last two cars averaged 38MPG and I could get 41MPG when driving very carefully (not very often). My fuel consumption on my present car has improved slightly to the 34MPG figure since I replaced the thermostat, it had been stuck slightly open. I do get a strong smell of fuel when driving with the sunroof open so I think I may have a problem somewhere, however, seems I may just have been lucky with my last 2 Gti's getting on average 38MPG. Be interesting to hear what others are managing to get.
