Well I go through about a tank a week. I did well for about 40 miles, kept it under 2000rpm. Then I turned the metal up and I was in a rush so the last 20 miles were in the redline, great fun though and the car isn't so bad to drive/handle considering the lows and wheels/tyres, etc.
I'm 100% on V-Power now, but the nearest station is a 20 minute cruise up the motorway. Was out the other night and I said to everyone I'll see them in 40/50 minutes. They looked confused when I said I'm getting fuel (there is about 10 petrol stations within 5/10 minutes hahaha).
This is why I don't mind taking it off the road and using the work van!
