We don't have anything about base miles in the system. So the best way to start is the next time you fill up your tank. If you're using odometer tracking jot down the odometer reading, enter that and your fuel-up details here.
If you want to use tripometer tracking instead, reset your tripometer at your next fuel-up, and then get the details on the following fuel-up.
Hi.First post, new user!Quick question...as this will be the first data i will be entering, can i just enter the odometer reading after a complete fill and just enter that without the fuel amount?Soz if im thick
As far as I understand it, the first time you enter an odometer reading it is just setting a base line. The second time, fuelly uses the difference between the two readings as the miles, and the fuel amount you enter at the same time, to calculate the mpg.
Personally I've only used the trip meter (tank miles) method.
No, they don't have to be in order. If you missed a couple fuel-ups, just make sure you mark the new one you add as missed. Then when you find your receipt (hopefully with your odometer reading written on it) enter it and edit the fuel-up you marked as missed to remove that missed a fuel-up setting.
