Fuel milage!

[HTRDHLR]

I have just passed the 5000 mile mark on my dually and the race season has also started so I have been towing a fair amount recently. I have noticed my around town to work and back has jumped from 13. 5-14 mpg to around 16 mpg!!!

fuel and mileage

The fuel mileage should get even better. Of course you may just use more pedal to go faster then... Someone on the forum had said that the Dodge ECM is programmed to increase fuel rate (i. e. power) as miles go up, and that full curve could be obtained after 50k miles. I know my 99 makes more power now (at 55k) than I had at any other time. That fuel delay is supposed to keep more money in Dodge's coffers as less fuel means less parts breakage under warranty.



BTW, what kind of racing are you into?

You also have gone up in mpg because winter mix D2 is outta here til fall. I always see an increase in spring, and subsequent decrease around late October.

I get better then 20 unloaded, and about 13-14 when fully loaded (3500 # Lance slide-in) and pulling a couple of horses or a Harley in an enclosed trailer. But mine's a stock 94 5-speed.

Mine has 29,000 on it and since I have been towing a trailer and a long trip (1,000 miles) in one day at 75 mph, the mileage has gone up to around 18-19 going to and from work and it got 22 mpg on my last highway trip with the speed between 65-70.

good mileage...

About the only way I got 22mpg, was when my lift pump was going south, and I was running with very little fuel. I would be weary of a dodge 24V that gets that good of mileage, as those nasty little lift pumps die all of the time.



Mike Ellis---As far as the mileage goes, a lot depends upon aerodynamics, weight, bore/stroke configuration, turbos and injectors, overdrive ratios, and some other things I have forgotten. I know a lot of powerstroke F250 owners that get 25-28 mpg with their 4x4s. Of course they are also plugging them in or starting them every two hours when cold, doing expensive rebuilds at 180k-220k, and wishing that they could work on their engines without going to a dealership every time.



Drive your Cummins and know that it will be around longer than your dad's powerstroke.
