Just purchased a 2000 dodge 2500 with a 360 v8, 265x75x16 tires, quad cab, 8' bed, I was thinking about the diesel but since it would be used just one in a while, I went the gas engine route.
I expected around 16mpg highway with the 4.10 rear doing about 55, but the truck's computer is saying I'm getting 8.4 mpg with an unloaded bed? I went out on the highway and cruised about 55 for 10 miles and still reading a tenth better at 8.5 mpg. When I fill up I will hand calculate... but how accurate is it to read the mileage from the on board computer?
Is there any sensor or other issue that could justify such a bad gas mileage if I find out that it really is that bad?
Thanks in advance.
