Measuring mileage

[JimmyM]

I'm about to go on a trip of about 150 miles. I'f topped off the tank and reset the trip counter and average mileage display. I've also got Torque installed measuring mileage as well. I want to see what I can expect on long trips.

Question... Do you guys usually see a good agreement between measured mileage (trip miles/ gallons to refill) and the average mileage display on the dash?

Ok. The outbound trip is done. I was driving smoothly and stayed around 70 MPH.
165 miles, 8.9 gal = 18.6 MPG
Truck displayed 18.9 MPG
Torque showed 17.8 MPG
I entered a correction factor of 1.045 into Torque.

How does this look for mileage compared to what you guys are getting?

I've checked several times and I find the dash display to be quite accurate. Normally within a few tenths of pump/ odometer calculations.

I just made a trip from where I live up to Maine. About 150 miles.
I was really careful but wasn't dropping below the speed limit. I did take advantage of following semi trucks (not too close). I got 21.4 MPG. Not too shabby.

The best I have gotten was 18 on a trip. I have the 3.73 gears so it's not setup for MPG. The display is usually within .5mpg of the calculated.

My lie-o-meter is pretty accurate, too, within .5 mpg. I was pleasantly surprised.
