but i'm pretty sure everyone uses this method already to determine mileage. There is no other way as accurate than hard numbers on your gas receipt. Just make sure you reset either trip A or trip B.

Anyone here keep a log book of mileage in their cars and update it with every fill? Yea, thats taking it a little too serious but I always thought it would be a good idea if someone actually took the time.
