7.9Gallons/4 Hours is 1.975 me that doesn't sound very good

can anyone tell me what they are getting with propane?

and does anyone know what the equivalent gas engine is getting for GPH?
If you look at btu's of gas and propane your numbers actually are about correct if the engine gets 1.3 to 1.5 gph on gas (which most would say they get).

The propane supports say they can get better due to effiencies etc but the math does not lie. Your about right and yes if the rpm goes down it will take less gph (gas or propane). But blade tip speed changes and ground speed changes also.
