All of these numbers are very close on every fillup. Truck is bone stock 2004 automatic. Tire pressure 55 in the front and 50 in the rear empty, then 65 in the front and 65 in the rear when towing. truck has 38000 miles and had always had the same numbers ever since i bought the truck. Never had a problem.

15 city on winter fuel +.5 for summer fuel
Highway avg winter fuel 16-17, summer fuel avg 18 both at 81mph

Will get 19-20mpg when I drive 74mph or less

Best yet was 19.8@82mph for 350 mile trip.

10-12mpg pulling 24ft enclosed trailer@81mph depends on the wind.

All calculations are done by hand. I drive hard.



2003 2500 4x4, 48re, green cold air element, Dr. Performance 85hp module and Power Up Gen 49D fuel treatment in every tank. GREAT TRUCK!!

How annoyed do you get with the Placerville stop lights on a daily basis?



14.6-17.2 commuting, depends on how spunky my right foot feels.

truck has 1400 miles on it, bought it last week, and had 320 when I drove it off the lot and drivin the wheels off it since.

Anyway, filled it up twice and checked it since the truck came with 3/4 tank off the lot .

First tank was 17.33 and the second was 16.8. That's about 75% hwy at 2000 rpms (about 72mph) and 25% city spirited driving. This is hand calculated, I guess I got a "good" one. The second tank was for ULSD and so is the current third tank... don't know about the first tank.

The overhead says anywhere from the high 17's to low-mid 19's at all times. I figured it's about 10% too high.

Truck is a 5.9 in my signature.

Hand calculated, I am around 15-19 on average. I usually see on the overhead around 19 cruising down the GSP at 65MPH.

I'm getting 12's in the city but I'm only driving about 6 miles to work, hardley enough time to get it warmed up. Best is 18 in Colorado mountain driving.
What really gets me is my computer is always showing 2 MPG better than I get!! Hope to see it get better, still breaking in with only 6500 miles.
