MPG calculations

[Toms306]

second method, its most sensical.

Also toms306 is a retard if he thinks you get 0mpg with the car using no fuel and still travelling....
If i knock the car off and travel 3 miles downhill thats 3 free miles, them miles will be infinite but add into rest will give true average mpg reading for tank..

Yes I might be a retard, but you aren't doing any miles PER GALLON as you aren't using any gallons, I don't see how thats difficult to understand tbh.

I use the free calculator from Torquecars, also use it to calculate journey costs etc.

I also use this, mainly for the pence per mile feature - MPG on its own is a usueless figure lol.
