I was thinking about the 582 vs 670 fuel burn in the same airframe...? If I understood correctly...the 670 puts out 89 hp and burns less fuel...Herb
Fuel burn from one aircraft/engine/pilot to another is not consistent and comparisons are not accurate. For my own personal use, I have found that the only way to get accurate fuel burn is during long cross country flights where the throttle is set at cruise rpm and left there. The flight should be started with a full tank and topped off on landing. I get great fuel burn when I am flying local and playing around the airport. A lot of people figure their fuel burn on this type flying. Then, during their first serious cross country flight, they are shocked that there engine is burning so much fuel. john hmkIII

However, how we get our fuel burn figures have to be consistent or that aren't any good. That's why I shared the illustration about flying around the patch vs cross country. It takes fuel to make power. john hmkIII
