It's simply the stupid way they do the click wait click fill that can in no way be accurate. Maybe someone is filling on the pump next to it??? Then the pump pressure will be different.
Fill that sucker to the top each time! I do it every time, sure it takes a few more minutes but I know EXACTLY what amount of fuel I used.
That tiny DEF nozzle is very sensitive, no way that is accurate.
Yet some find it strange that other care about "exactly" what amount of fuel they use.
Is it like a kid waiting for Santa as Christmas to see if you are .1 mpg better or .2 mpg worse than the last tank?
Is it a cause for consternation if somehow mileage was worse or celebration if it was better?
