Uh, we can't change the laws of physics. It takes a given amount of fuel to
make 30,000 Btu of heat. Not every grill will utilize that 30,000 Btu the
same way, but every single one of them will use the same amount of fuel to
generate it. I didn't write the laws of physics, but we all have to abide
by them. Propane has 91,044 Btu per liquid gallon no matter how good or bad
the burner is.

The propane has that much RAW energy potential, yes. But remember
that's if it is *all* burned. Inefficient burners just don't do that.
(same with 2-cycle and 4-cycle engines; many of 'em send quite a bit
of unburnt gasoline out the tailpipe.)

Example: high efficiency condensing propane furnaces run at 95%
efficiency--but those are spendy. Most propane furnaces run at a
lower efficiency, by a fair bit.
