17 MPG when towing my outfit or not. GMC Jimmy 1998 vintage with 320,000km on it. Never alters.
I don't fill up before and after each tow, so i can't give accurate numbers, not sure how everyone else is figuring theirs, unless they top off after before and after each tow?
I can see it in your case. My case, as I don't have to travel far, is probably to similar to many others. I'm not filling my tank for a 35-40 mile RT. Doesn't take a brain surgeon to get my pointIt is exactly 200 miles RT to Solomons. The truck has a 26-gallon tank. I fill up when I leave and I'm on empty when I get back home. Repeat the trip 50 or more times with the same result. Doesn?t take a rocket scientist to figure it out.![]()
I suspect people are using the inaccurate overhead MPG displays in their vehicles.
Maybe it's close SOMETIMES, but none compare to hand calculating.![]()
Enjoy that older Cummins... the newer Dog Rams get worse mpg than my gasser.I get 20mpg empty with a 550HP 8000K lb. truck![]()
