Truth be know he is lucky to get 9 mpg and his son is going college as soon as he finishes up at the state pen...

Thank you Sir.

I'm laughing at your post because you are exactly right...the MPG claims seem to get bigger with every post!

Happy New Year to you and Thank You for your service!

As other have said, the best (only) method is to use an app to track it. Trucks on board 'lie meter' says 17.7 across 19000+ miles. Across the last 11 fill ups, (10 tanks averaged, 4420 miles) the math shows 17.4. For an individual tank, the largest difference from the truck, to the math has been 19.5 on the display, and 19.1 for the math (That tank only had one very short regen). That said, the last two tanks, the truck actually underestimated (was lower than the math). The camping season was over by the time I started tracking, so this has all been 'unloaded'.

Some of these guys must really have a lead foot, that or the 3.31 rear end makes more of a different than I thought it would.

So I by no means drive slow but your question got me wondering. So I did the math, mileage divided by engine hours gets me 45.76 mph average

BTW my truck always says I get about +1mpg compared to what acar calculates.

Did you have a performance tune added?

Nope not yet. Just the tires and the forscan change to make speedo correct. It's pretty bad.

You should be getting much better MPG than that.

I know this is old but I have an F-250 gasser that is lucky to hit 10mpg empty and runs about 7 towing. Has the 6.8 V-10 and 4.1 rears.

nah I’m actually thinking to remove the V-10 and put a Cummins 5.9L in. It’s a good work truck and has a service bed that’s actually in usable condition so I think it pretty decent. Mileage is murder though and I’m pretty sure it’d do better with the engine I’ve picked out.
