why worry?
try my 4.2v8 rr bobtail for a week you will be glad of your 28mpgNot worried..............just a tight arse:5bdriving:
Try filling up with your normal grade of fuel from a Shell garage? They claim a slight increase in mpg.... maybe worth giving it a go. Some people on here reckon supermarket fuel and certain brands can reduce mpg. Let us know if you do and what results you get. We are all tight arses!.... just wish I could get 56mpg like I get out of passat my tdi
