Always found the following very accurate formula to calculate g/p/h fuel burn for most normally
aspirated internal combustion gasoline engines. Extremely accurate for aircraft..also pretty close
for autos, other types, even marine out-boards.
Just use 1/2 pound per hour per HP at whatever throttle setting is being figured..i.e.
250HP engine operating at 50% power... = 125 HP, x .50 = 62.5 pounds or approx 10 gals per
hour. Using 6 lbs/gal.for weight of gasoline.
There is quite a good number of Tips etc. under the
