Another mpg result while towing…

I came back from a 1566 miles trip in NorCal and Oregon, 1172 of which towing a Lance 1995 weighting around 5500 lbs (the rest are local trips without the trailer). The miles per gallon reported on the lie-o-meter were 11.0 on average. I have to admit I kept it quite easy, around 60-65 mph, but still I am quite satisfied considering I had a lot of mountain to do…

I just did a 1300 mile trip towing our 8K lb Airstream. The Lie-O-Meter says we averaged 14.3 MPG. I kept the speed around 66-67 MPH on the highways and the speed limit when they were lower.

You can put the dash in engineering mode and apply a correction to the AFE (mileage).

I think he was asking if it has 3.73s or 4.30s.

Good to know. I didn't calculate the MPG manually to know the exact MPG. The on board computer may have been correct. Usually they are close but not always.

I completed a 3000 mile trip pulling a solitude 5th wheel. The truck was pretty accurate. I calculated by hand each time I filled up, and the truck was pretty close, usually within .5 mpg.

I towed 400 miles yesterday.
On board computer said 10.9.
Hand calculation was 10.845.
That’s a wash IMO.

I had one of my legs to Florida in February actually give the reverse......Hand calculated was almost 1 mpg higher than the computer indicated.

I do the "TFL" method....fill till it kicks off, then wait 30 seconds, then fill again till it kicks off. Just a way to try to keep it consistent.

I think I had to correct mine diwn 6%. Just towed 7k miles, heavy, with hills and the DTE vs the distance to destination would track to the mile over 220 miles.

Final result, 27k gross weight with 5er, 70 mph and 9.1 mpg. These trucks are phenomenal.

That is the way I do it too. Seems like good practice.
