What kind of fuel milege does a 2003 Dodge 5.9L Cummins get? automatic? manual? Highway? CITY?

 

Best I am gettting is 16 highway.

 

PM Tim Holt. He has gotten almost 30 going 55.

 

I get 23.7 hand cal. at 1800 RPM or at about 65 MPH.

 

City/Mixed usually I"ll see around 15.5 to 17.5 mpg, more city lower mileage,more hwy higher mileage this is usually the average for my enviroment considering how the county has grown with more traffic and more added stop lights.

Highway Interstate style driving I'll see 19 to 20 mpg.

Always hand calculated figures with 48K miles on the clock.

I just got 7 mpg pulling 560 miles.... And all I was pulling was a 10,000 lb trailer. Hmpf. I thought I'd get around 12.....

 

I have 110K miles on truck and average between 22-23mpg city/fwy. I was getting around 25 with EDGE EZ but took off as my mechanic told me that it would damage injectors. My carpool partner has an 04 Dura max and couldn't believe the mileage I was getting. I didn't tell him I had the EZ installed.
Mileage reaings are from overhead display not hand calculated.

 

My '03 4x2 auto 3:73's........got 23-24 mpg highway....keep your foot out of it....stay below 2000 rpm and mileage is better

 

In town I get 14.6 according to the thing on the ceiling. On the highway I get 18. But I drive 70 to 75 on the highway. I'm just not patient enough to do 65.

 

Biggest factor you can control, is keeping a soft right foot and staying around 1800 to 2000 rpm. I know, it's hard to do when you are behind the wheel.

 

my '03 truck in sig is the 305/555 HO and will average 22.5 on my 110 mile a day commute. All highway miles. Towing the 11200 GVWR 5er averages 12.5. All pencil figures and is not just a best tank number but are averages over many tanks. Don't have a city for mpg figures. The '03/'04 305/555 HO engine gets great mpgs as most 1st gen engine do with good power.
In '03 we had three different engine hp/torque available. the 305/555 HO the 250/460 and the California 235/460 engines.

On my 03 4wd SO, auto, 4.10s, if I keep it at a reasonable speed, I can get 20-23. That is all highway mileage. In town, around 16-17. All hand calculated.

 

And how fast were you running when you got that 7 mpg? I pulled a 24 foot enclosed trailer with about 10,000 pounds load inside and got 15. But then, I was running 60 to 65. That was over a 980 mile pull from Amarillo to Nashville.

 

33 mile trip into work 95% hwy @70 mph with 72k on the odometer got 19.96 on my last fillup. Averaged 17.5 to 18.5 during the winter.

 

I had a 95 with 282,000 miles and it got 20mpg always. I now have the 06 and it gets 20-21 after I got the pcm update for cold weather starting/performance. Thats both hand calc and overhead readout.
