My fuel milage findings

[Quilbilly brian]

18. 5mpg with 265/70/17 tires going 70 mph with my wife and some sand bags in the bed for weight. This was hand calculated using a GPS. I kept it on cruise locked at 70.
Best overall mileage was through Nevada.
Had a head wind coming out of Phoenix to Spot light NV where I filled up and got 14. 5
Stop and go around my neck of the woods I get 16. 5 to 17 mpg

My 6. 7's mileage is similar to what odinjunior gets, even less when we had -20 to -30 weather and lots of idle time. Mileage should improve in warm weather when cold / stiff fluids, winter blend fuel, and extended idle time are not part of the equation. I think the engine calibration in cold ambients might play a part in lower fuel economy too.

I wouldn't mind as much if I had 4. 10's in the Diffs but I've got 3. 73's

Search for "Road trip with pics" under my user name in the C&C forum, and you will have a very good example of the difference from the overhead and actual milage. Sorry, but I don't know how to link to it and post it in this thread. Maybe someone with better computer skills can do it, so the others can see.

Try using a hand held GPS to check mileage. Mine is very accurate.
