Mileage Accuracy

I started an experiment with the last fill up of the tank of gas in my truck. I reset the truck’s trip odometer, and also reset the trip computer in my Garmin Nuvi. After 140 miles or so, the Nuvi is reading a little over 2.5 miles more than the trip odometer. The question is: Which one is right? I guess I’ll have to find a known distance, and reset both of them to see. Something to add to the to-do list, but certainly not at the top.
