chaps,
this is now frustrating me as i cannt work out if the car is running efficeintly so i would appreciate input.
Now running around on short journeys i sort of accepted 27.9mpg average (ipk)..........but i went to cornwall and back. At the end of the down leg the computer upped its average to 31mpg. Now on the way back i did a brim to brim fill. Driving was approx 50miles faffin around cornwall and 365 miles home.
On the way back i did hit traffic. Now a brim fill showed i had actaully averaged 38mpg yet my IPK showed 32.8mpg..........
i know the brim fill is the best way but would memebers still say my car is poor on consumption ?........i just need to know if i should be looking at doing something (i have ordered a tuning box)

any ideas
