Ayuh,.... Usually, Best Economy is at Idle, trollin' speeds...
Best Efficiency is probably in the 3500 rpm range...

Re: fuel consumption

The best thing to do is test it for range. If you know the size of the fuel tank, then fill it, and run her for about 1/2 tank and see how far you get. Multiply to get total range.

If you don't know tank size, pack some extra fuel in portable cans ad run her main tank dry. Now use the portable fuel cans to get to the gas station and fill her up.
