A-B-A Testing Gas Measurement Methods
 

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.

Scangauge. I seldom am looking for absolute measurements. A percentage increase or decrease is fine. If you don't change the settings on the scangauge, it measures the usage (mostly) the same way.

Agree SG2 or similar is better, but SG2 doesn't work with fuel changes as in E0 vs E10 etc...
