To determine fuel used by clicking off waiting 30 seconds then squeeze/click is a joke.

Thanks for posting!

Please explain...

They are just using consistent/repeated technique when filling the tank each time. I don't see the problem.

What do you propose they do?

No two tanks are going to cause the fuel nozzle to shut off a the exact same time every time. If they filled the tank to the top each time would be more accurate. But they may spill a drop so that is not an option.

Only real accurate way would be tie a seperate fuel tank into system that can accurately be re filled to determine exact fuel used.

It doesn't matter if one tank consistently fills more than the other. Its irrelevant... THe key is to consistenly fill the same tank to the same (or close ot the same) level at each fill. Whether one fills to the top each time and the other always has a gallon of space left doesn't matter. As long as its consistent each time your only measuring what you are able to put into the tank. By using the same pump at the same station using the same filling technique (fill till click, wait 30sec, and top off)is about the best you can do in a test like this.

Yep - exactly correct
