Are gas engines ever going to catch up?
Our creaky old Cummins powered truck (bought used) seats 4, does about 20-23mpg bobtail and 12mpg towing a 5th wheel trailer at 22,999lbs. It's mileage is somewhere in between hauling a camper and/or...

Good post, naturist.
I've heard many people say, "Diesels are more efficient than gassers."
That's not necessarily true, I say, since to be fair you have to compare their efficiencies at the same compression ratio.
They say, "Huh? You can't do that."
If you don't, then you're comparing two different engines and you're handicapping the gasser.
I have to disagree with the premise. Diesels are more efficient in part because they can have more compression. That's not a matter of being fair, it's a matter of physics. The gasser IS naturally handicapped in this regard and always will be. Has nothing to do with being "fair". You have to take the engines as they come and technology allows for diesels to have more compression.
