I don't feel that the short distance used and relying on foam to click off the pump would give an accurate number. If one of the trucks has a filler neck better suited to not backing up in the neck it will really skew the numbers.

the number would have only went up with highway cruising involved but it's a good representation. If you fill the truck up the same way every time that you'll get accurate fuel readings from the pump.

I fill up to the click off and I'm right in line with the computer but to get a real test run trucks through a full tank and a regen and see what happens.

I'm betting ford will be lower cause even though they have a higher gear they are always the heaviest.
