Technical MPG All Over on Trip

Hi

I take it this is instant MPG not the trip average. The instant MPG is highly variable. it may be low double digits under hard acceleration or up hill and over a hundred with your foot off the throttle down hill. This is normal. Many cars have a top limit of 99.9 MPG so as not to show implauasible figures. It's only really useful to see if changing gear makes a ifference at steady speed or as a reminder not to press so hard when accelerating unless you need to. If you really know you car and use instant consumption reguarly on a specific bit of road and speed it can give an indication of problems if consumption goes up under those specific conditions.

Yea 141.2 mpg means your on instant mpg not trip mpg

141.2 is easy to get to - as that just requires a semi decent hill....

The fun challenge is seeing how low you can go!

Ive hit 11mpg in mine.... sooooo wanna get a single figure but i dont think its possible
