For whatever reason, that didn't even cross my mind.
On the other hand...I wonder how much efficiency is gained by using a gaseous fuel at partial throttle...you'd have less vacuum to fight, ie less pumping losses. All I have to work off of is when I lent out my dual-fuel generator...they ran it all day and into the night and didn't even use up a 20lb tank. iirc.
