I filled her up today and to my super suprise heres what it weighed in at...
230 miles @ 25l (BP Ultimate) = 41.82 MPG
Miles Per Gallon 41.82mpg
Fuel Cost Per Litre £1.02
Fuel Cost Per Gallon £4.64
Fuel Cost Per Mile £0.11
so it must just be that I drive with a lead foot - the car itself seems to be running pretty reasonably. But that was at 65 mph avg!
