I am going to start doing some A-B-A testing and was curious of everyone's methods for measuring their fuel use. I don't trust gas pumps, even using the same one has given me different results. So I was planning to use a digital scale to measure how much fuel I placed back into my tank after the testing. Fill the tank to the point I can see the fuel in my long-neck funnel, run base test and weigh the fuel before I refill and then after to get the amount used. I want to be able to trust the refill every time, and with my '12 civic lx I won't have the time to run through an entire tank of gas for every test run. I have laid out a nice 50 mile piece of road that will give me some normal conditions for highway travel and the 100 mile round trip won't take more than 2 hours to complete.

Short of a laboratory conditions will this method work well enough for getting averages?

How do you measure your fuel use?

Thanks.
