Yes indeed, how are you calculating that and how do you drive and what modifications if any have you made to get a return like this?
It seems unbelievable.0 -
I'd love to know how anyone gets 68 mpg or 74 mpg out of anything.It's my problem, it's my problem
If I feel the need to hide
And it's my problem if I have no friends
And feel I want to die0 -

No it isn't. The display may say that, but the fuel costs don't. I know, I owned exactly that model. 700 miles from 62 litres was just about the maximum achievable.0 -

With a bit of tinkering using a sequence of button presses etc. rooted out on the internet, I can make an adjustment to my cars OBC mpg reading offset such that I can get it to say 99.9mpg urban cycle.
OBC readings can be inaccurate anyway.
In short I don't accept OBC readings on any car as proof of actual mpg.0 -
Over the last 4 tankfuls, my car has averaged 56mpg (calculated using the brim to brim method). The indicated average on the trip computer was 62mpg.
I drive a Peugeot 207 110 HDi Sport.
My ultimate aim is to get 700 miles out of a tankful.... however, I don't think it's going to be quite possible. Won't stop me trying though!:money:0 -

Use the "brim to brim" method working out how much fuel you have used and over how many miles to get an figure. Then change your driving habits for the next tank full and make the same calculation again.
If you want an even more accurate figure, use the same pump and the same garage, brim the tank and record the starting mile age. Drive for a few thousand miles recording how much fuel you put in. Finally brim the tank again adding that amount of fuel to your running total of fuel used and note the ending mileage. Now you can calculate mpg over a much longer period which will be more accurate.0 -

Actually you may be able to, if you want to that is:

Car trip computers are normally fairly accurate, except that the speed over reads by 10% for the uk market. So subtract about 10% off your MPG and thats what it is.0
