Weighing the mass of fuel.
I have found that a small secondary tank that I can quickly attach and remove for weighing on an accurate scale is the best way to verify fuel use. Of course it depends on your application.
I also use an early model Garmin Hiking GPS that is accurate to 1/100th of a mile for distances traveled.
This setup is much easier on my old Mercedes and vehicles with inline fuel pumps versus in-tank pumps. But, it yields accurate results.
