5.8 average I'm guessing but you don't mention ratio

In almost 30 yrs of driving I've never seen a big cam Cummings or any other non computer motor get this kind of MPG. Some people say so but it will be another story made up by someone, you know " you aint gonna believe this"
If you are lucky and seeing as how the motor is 7yrs old the high side maybe high 4s but more likely around 4!

i wil keep track and post the mpg when i know also.

If he ran empty this may be possible. To bring us out of the 3 to 4 mpg motors they introduced us to computerized motors but with most trucks averaging low 6s 5.8 for that old of a truck and motor would be lieing to him. Now there are trucks getting higher than low 6s but nothing of that age!

I forget what the 290's got for mileage but it's pretty much the same block.
