Cummins fuel economy
Hi I just bought a 2004 Dodge cummins 5.9 with only 115000 km on just wondering how many km guys are getting on a tank of diesel. I'm only getting about 600 km in winter that bombing around town with a little highway but feel like I should be getting better. Even put in a smarty jr. Thanks

I've done as good as 24 mpg. Have to keep the rpm at or below 2000. A good, hot tune gives me the best mileage, as long as I keep my foot out of it. If all the driving is done on the interstate, it'll go 650 miles between fill ups. my upgrades are; Hamilton cam, 60 horse injectors, AFE cold air intake, 4" exhaust from the turbo back, Edge e-z, Airdog 150, and Industrial Injection phat shaft turbo.
Play with it a bit- intake, exhaust and good fuel filtering are a must.

12mpg does seem lower than usual but then again if around town you are constantly stopping and going I can see that number easy. It's a heavy truck to stop and then to get moving again and you have 6 tires opposed to 4. what size tires are you running? If they're oversize you'll see about 1.5mpg less per inch added over stock. What rpm are you shifting at? I see about 15 in city- 18 ish hill country driving with 33's
