Hey was wondering what everyone was getting for mpg
I would post mine but haven't driven it enough yet i just got it LOL

 

First of all, Welcome to the forum, and congrats on your purchase. By your location of Fort Campbell, can I logically conclude that congrats are in order and a thank you for your military service? Hope to see you posting often this is a forum for Durango Owners, by Durango Owners, there is plenty of knowledge, experience and geographic knowledge to understand how the D reacts in varied areas of the country, cold, extreme cold, ocean, desert, hot, midwest etc... With the above said, onward to your problem..........................


Engine and model please? Driving conditions? 2wd/4wd? You say you just got it, what have you done for tune up since purchase, or what was known to be done either during your purchase or immediately prior to purchase?

Basic checklist

Spark plugs, rotor, cap, wires, filters, oil change, trans fluid/filter, brakes, rotors, pads, shoes, wheel alignment etc..... Don't hold back, anything even seemingly small might be a factor.

Great to meet you!

My built 5.9L is rolling at about 15.2 Hwy at 75 average and 13.5 city. If I put my foot into it reverse it gallons to the mile.......LOL

 

Hey I have a 5.9 R/T and I'm only getting 8 in the city 13 on the highway. Maybe cuz it has AWD ? I know I need a new O2 sensor. But the truck is maintained very well.

 

ur foot will effect the millage of these trucks BIG time

 

I have a 5.2L 1998 SLT
i have currently replaced wires, plugs, cap and rotor, gave it an oil change.
i believe they ad the wires on the wrong firing order when i purchased it
have yet to replace brakes cause i need to find a 3/8ths inch allen wrench or a 7mm i dunno, some play in the steering wheel, shifting driver seat during acceleration,
and spark plug #7 is seized how do i get that sucker out?
but it runs great now
and yes I have been in the Army for 7 years

 

"and spark plug #7 is seized how do i get that sucker out?"

Put some PB Blaster down in there and warm up the engine well, should come out.

 

Getting 14 city, 17 hwy, 9-10 towing 20' toy hauler trailer. My #5 plug is hard to get out due to tight clearance between the plug and metal shield around the plug. A real pain. I coat the tip of the socket with lithium grease before inserting it into the shield and it does come back out easier.

 

Overhead computer module says I get 13.4 to 13.9. Rare I take it on highway trips. If a friend wants to borrow me and my rototiller, I losen the handle, load it in the back, and down the highway I go. :<)

 

I was getting 19-20 yesterday with cruise control set at 70. Overall average was 15.8. This is after a new front O2 sensor, new MAP sensor, new valve cover gaskets, running some Marval Mystery oil through the fuel tank, took the ski rack off, and new front suspension componets. Before all of that I was getting a max of 15 on the hwy and an overall avg. of 11-12. I'll check back in after the new aif filter and hypertech tuner.
