What Kind of Fuel Milage Are You Getting From Your Cummins
I just clicked over 10,000 miles yesterday on a trip. About 250 miles round trip with cruise control on as much as possible at 57 mph. Computer was telling me around 21 mpg average but I have about 11% larger diameter tires. When I do the stubby pencil method and add in about 10%, comes to just a tad over 23mpg. I was looking at some engine mods but kinda hate to mess with success. ;o)

With the cruise set at 76mph, ac on full blast(to deal with the 97 degree heat in Texas) and auto trans, I got 19.5 from last tank. My truck has about 63,000 miles on it now. My milage got better between 10,000 and 20,000 miles on the truck. When I put the Edge EZ on I gained about 1 1/2 mpg.

Not bad mileage at all. How is the Edge EZ working with the auto trans?

Mine is averaging about 19-19.5 on the computer. It seems to vary with where I buy diesel. I have the real low rear end and the 3500 so it sucks diesel on the free way.
The biggest improvement I have had is switching to the synthetic oil.
Does it make any difference with the tail gate down or with a air gate? I tried this with my Ford 150 but with the new low cd design it made no difference.

Any of you use a fuel additive? I am using John Deere Summer Formula but have been experimenting with Power Service and Howes.

the EZ seems to have no effect on the trans at all. I have never felt any slip or shudder. I use the Shell Rotella fuel additive. Cummins seems to run quieter when I use it.

after many years of owning tractor trailer units, I always used Howes lubricant. THe name tells it all, lubricant.. Power service and most of the rest of them are mostly alcohol. At least with Howes, you freeze, and they pay up. I have an 01 quad, 4 X 4 short bed, 6sp tranny with the HO motor.. 16 to 21 MPG and it is continuos. I do the worse and that is 4 mile trips here and there. Once, with a heavy tail wind, on the way to Boston I got 26.

Mine is a '94 2500, 4x4, 3.55's, 5-speed, with 265-75R-16 tires; milage varies between 17mpg worst recorded, and 25mpg best, depending on speed load and type of fuel.
Using a winter blend fuel and hauling heavy gets the worst mileage. Summer #2 empty with cruise set to 55, gets 25+ mpg.

Just did a trip to Florida and back. Best tank was 17.85 and worse tank was 15.5. I use Lucas fuel additive. My truck is a 02HO 4x4 with 4.10 gears. I have a comp box stage 2 inj, 4" exhaust and mega cannon air filter. The gears hurt my mileage on the highway. Going to a 285 tire to help with the gears when the factory tire are shot.

I've got the '03 H.O. diesel (12,000 miles), 4x, factory tires and 4:11 axles. Pulling about 15,000 around town I get in the low teens, empty on highway 17-29 on high end.
