Now, i've had a little think about this, but i end up getting totally confused, can anyone help me?

Just did a 1000 miles round Devon and Cornwall the last two weeks, and the trip computer says i got 8.9 litres/100 miles. Now, i know 4.55 would be 100mpg, so 9.1 is 50mpg, but i'm stuck on the exact calculations

8.9 litres = 1.9577255 Imperial gallons
100 / 1.9577255 = 51.0796841

8.9 litres = 1.958 Imperial gallons as per http://convert.web-max.ca/index.php?select=80&page=2
so 100 miles per 1.958 gallons = 51.07 miles per gallon (1.959 gallons @ 51.07 mpg = 100 miles travelled).
Not a bad return I guess you're driving a diesel.
Grr beaten to it lol

Your towing a caravan that weighs at least a ton, PLUS the shame of it is creating massive wind resistance.....

Your lucky your getting 25!

by the way, I drive a diesel and it only costs me 20p a litre to run :)

(home made biodiesel)

The old car was even cheaper it was only 5p

(filtered chip shop fat)
But the new car wont run on that it has to be proper biodiesel
