When I fuel up, I write my odometer reading right on the receipt, which I make sure to get. If I'm caught without a pen, I do one of several things. 1) Take a picture of the pump with my phone as suggested elsewhere. 2) Most phones have a feature to write a note and save it in the phone, or just send yourself a text message with your odometer reading. 3) Zero out your trip odometer, and when you get home, record your odometer reading and your trip meter reading and subtract your trip odometer from your odometer to arrive at your odometer reading when you filled up.
