Another gauge corrector--cheaper than MeterMatch, 33.00

how about running a fuel flow meter and just keeping an eye on it? 15 gallons flows 15 gallons. When the meter has flowed 13 gallons time for a fill up and a reset. No sure how much these are but this one is $35. It may measure way too much like 1-60 liters per minute...

Interesting idea.

Biggest flaw I can see is that you are assuming how much gas you have in the tank and having to remember how much you put in last time. It could bite you in the end if things get out of whack and you think you have 13 gallons of range but you only have 10.

At the same time, seems like it would be the bomb for calculating actual MPG.
