How to estimate fuel consumption - best method!

[jonathan150cc]

We can never get this down to a pure perfect science because there are simply too many variables that go into filling your tank.

The only thing you need to worry about is being consistent. If you like the first click, do it every time. If you like to wait until gas splashes on your hand, do it every time. What's important here is to establish a consistent baseline. Whether or not you are techinically getting +/- 1-2 MPG is insignificant in real world application. Unless you are just anal about details that you have no control over...

It is insignificant

until people start making fe claims based on a fill or two.

[jonathan150cc]

Yeah but that's exactly why people should measure based on averages, not individual readings.

That was my point. You don't even have to be consistent, as long as you average over enough tanks.

...Of course, if you're very inconsistent, "enough" tanks could be a couple of decades' worth.
