Need real MPG #'s

[TRUEBLUE]

Looking at a 05 4x4 dually 6spd with 3. 73 gears and I want to know some real world mpg #'s. Thanks Todd

Salesman will tell you 22 city and 26 highway, as will a select few here. Your real mileage will be about 14 City and 18-19 Highway Unloaded

 

[JVolpe]

Thats if you are lucky... You will probably be able to make those numbers with a 6spd, they seem to report a little better mileage than the autos. I now get about 14mpg city unloaded, but only average 16 empty on the highway at 75mph. I am at 19000 miles now, this is ok, but not what I expected from a Cummins diesel.

17-18 mpg rural driving (I stay away from the city)



9. 5-10. 5 towing at the GCW

I'll be honest with you, these are just my numbers and remember it really depends on your driving style. Average for tailer towing once a week at 14,000lbs for a 100 miles and 27,000lbs for 15 miles with empty daily driving on that tank as well is 13. 4 MPG. When I just cruise the highway at 75-80 empty I see around 14-15 MPG. I am the first one to admit that I do have a heavy foot alot of the time so these are my numbers. I record these numbers every time I fill up because of my business. Corey

One more thing I just remembered that a few weeks a year I tow alot and have seen my MPGs go down to around 12. 2 or so. There was one time that I towed a little pickup on a flat bed trailer at 70 and got 14. 7 MPG fighting head winds. corey

fuel milage will vary considerably with truck weight/driving style. Thats one reason you get folks that can't believe when someone gets better milage than they do and that all diesels get the same milage. I don't have the 325/600 engine so I can't comment but just some observatios readin' fuel milage threads... ... ... . JIM

15. 5 average pulling 3,000 to 4,000 (empty trailers) up to 12,000 pounds (loaded with 1 or 2 tractors) about 80% of the time. I try to keep it down to 72 mph on the freeway. Sneaks up to 75 to 80 on me once in ahwile though. Lots of power. Also pulled a big stack of trailers back from Okla (about 1,000 miles).

Just hand calced last week 16. 35mpg all in city driving. I get about 19-20 on the highway but I drive around 65mph. I like to keep the RPM's below 2K.

Hand calculated no load. 16mpg around town,19 freeway. Tend to stay 70mph or below.

On winter blend fuel I seem to get right around 16 regardless of the type of driving I happen to do. I normally take it somewhat easy on the fuel pedal though, but there's still plenty of times when I open it up... Most of what I normally drive is rural roads. On my last trip on the freeway and then some city driving both tanks ended up averaging out to about 16 as well. Then again I like to run at least 75 on the freeway, and if somebody wants to play I'll play assuming it's safe... I've not had the opportunity to check on summer fuel yet. Hopefully slightly better. I've only got about 6500 miles so far though and haven't hooked a trailer to it yet to help with break in...

 

[JKlopp]

Overall average has been around 17 MPG empty. Truck has just over 16,000 miles. Includes all types of driving including up and down the mountains.

 

[TRUEBLUE]

Thanks that is what I was looking for,a wide variety of driving steyles and driving conditions. I have a friend that has a 04 600 with the 48re and he is getting about 14. 5 everyday. Thanks again Todd

 

[jwduke]

14. 8 on winter diesel & 85% highway miles

 

[RDoupe]

13 city, 15 mixed, 18 highway, I now have 9000 miles, 3:73, auto trans, this is all empty, lots of rolling hills, about what I expected.

Towing - 12 to 13. Empty 16 all around.
