I have a 2000 D 5.9L getting an average of 10 mpg. What is everyone else getting as far as mpg? Please include engine size & year. Should I be getting a better average than this? I drive on the freeway and in the city pretty equally.

 

i have a 98 D 5.9L 4x4 and i get about 13 on highway n 12 in the city...gonna go some exhaust and air intake mods n hopefully boost it up higher.

 

Anyone else?

 

98 Durango 5.2L getting 13-14mpg...? Sucks doesn't it.

 

1999 5.9l durango! i average 10mpg and drive equally hwy/town. mine is in perfect running order i.e no plenum leak fresh tune up. its a gas-hog just accept it for what it is.

 

I have a 2000 5.9 R/T tuned up to get about 11-12 in town and 13-14 on the highway. I'd bet I can get alot more if it were not for the AWD and the 3:92 gear ratio!

 

I've gotten up to 17.42 MPG @ 45 MPH before but I had my trans locked in tow.

In the city I get an average of 12.2 MPG and Hyw is 14.4 @ 70 MPH. If I go up to 80 I drop to 11.5 MPG.

I'm doing a study right now on a trip @ 100 miles HWY @ 75-80 MPH in cruze and will update. Update: I got 13.96 MPG

I have the 392 gears in my truck. In the Eco on my on board computer I average 13.2 it says.

I run 32X10.50 LT 15 tires.

 

14.2 city. I have not calculated hwy yet.... 355 gears.. Superchips Max Microtuner.....K&n cool air kit-plumbed to a funtional Ram-Air hood by Keystone.

 

i get 17 interstate an 13 in city with a 5.9 360 4x4 with intake TB an aircleaner, i figured i'd be getting less than every body else, because before i put my mods on i was gettin 17 city an 20 interstate

 

That sux, after those mods, you lost mpg's? I thought you would at least gain some or remain the same? Unless you have other mods you did not mention?
