Does anyone use a petrol logging app? Just bought a new car and would like to know how much it's costing me to run.
I've downloaded a few to try out but non of them work out the mpg in a way that makes sense. Meaning they'll use the difference from the current odo reading at the point of fill up and the previous odo reading to calculate the mpg based on the amount of fuel just put in the car. So if my previous fill up was for £60, and the latest was £30, the mpg it states is around double what it should be.
I can work around it, by logging the previous fill up cost at the latest fill up odo, but i'd like something that does the work for me.
