You're are correct Titen. The site I visited was comparing gasoline to water - and I cut/pasted the wrong value. Duh!
This means my model is 'rich' because it over estimates the weight of gasoline. This doesn't really impact the 'concept' of the model which quickly moves back to liquid ounces.
StrokerSix - I used a constant v/e of .85 in the model to make the math easier. But your point is well taken. Cruising involves bringing just enough HP to bear in order to overcome wind resistance. At lower RPM the the engine brings more fuel to bear per revolution - which is more efficient - then revvving higher at a lower v/e.
