I'm confused. Right i filled my car and reset the mileage. The next time i went to fill up i had done 260miles and filled 45litres or so (about £44 of petrol.)
I did a calculation on the internet and it said my mpg was 26 lol.
this works out @ approx 32 mpg mate
its easy to work out yourself what you do is run your tank right down,fill it up,take note of how much the petrol costs,run it right down again,take down what mileage you did,refill to make sure it costs about the same to fill bk up as your original tank,then devide the miles by how many gallons of fuel you used,for example:
lets say you fill your tank up and it costs £40,and its £1 per ltr,so you put in 40 ltrs,you then do 300 miles on that,so you fill back up,to make sure its about £40 that goes back in,and there there is 5ltrs per gallon,so you put in 8 gallons,so deviding 300 miles by 8 gallons gives you 37.5 which is your miles per gallon
