Which, while true, isn't the important measurement. When comparing fuels you need to measure MPBTU rather than MPG so that you get a fair comparison. MPG will only tell you you need more volume of fuel, thus a bigger tank. Finally it all boils down to MP$F (Miles Per Dollar of Fuel
)
So if augmenting with propane is cheaper per mile (by enough to make up for the install cost) then it makes sense, otherwise it's a waste.
On a seperate note, anything wrong with burning JetA other than needing additional lubricants?
