S40 Trip Computer MPG calculation

Tubski · Oct 11th, 2009, 12:19

I thought I'd try a long term average MPG calculation on my trip computer, so I reset it after my last service over 7000 miles ago now.

I did a 900 mile round trip last weekend and the figure went up from 34.9 to 37 mpg, which to me doesn't seem to compute for the whole 7k miles. Is it taking an average of the whole milage (which would be impressive), or does it just do (say) the last 1000 miles?

That is simply the average fuel consumption since you last reset it .. ie. over the last 8000 miles
