I have 2 Dodge diesels both with the same gears it seems and the 5 speed standard gets 18 to 19 mpg and the auto gets 11 to 12 both in non-pulling situations and hilly terrain in Hawaii. Is this what I should expect?

 

Over the last 890 gallons through my 5 speed, average 18.92 MPG, can't say about the auto. Maybe no TC lockup?

 

I have a 96 also but I get mileage that avg around 20 empty and 16 to 17 towing here in the WV mountains.<br><br> I am not sure why your mileage is so low. Has it got a plugged cat on it perhaps?

 

I've got a manual shift and gets around 19. I used to have a 95 2wd w/auto that got around 20 or so, sometimes better sometimes less, depending on how fast I drove it.

 

11 to 12 mpg seems kind of low to me. <br>With the stock tires and 3:55 gearing, I was getting about 19 to 20 mpg. I have since put on 33&quot; tires and adjusted for the larger tires, I still get around 19 mpg around town. <br>Freeway driving has gone up with the bigger tires and now I average about 23 mpg on the highway.<br><br>Have you done the standard stuff?<br>1) Fuel Filter,<br>2) Valve Adjust,<br>3) Clean Air Filter,<br>etc...<br><br>Also, check the timing, and make sure the exhaust is free from restrictions.<br><br>Rich

 

My 97 auto gets 17 in town and 20 on the highway at speeds of 70. If I hammer it to 90 mph I get only 17 mpg.

 

I have a 96 auto,cc,4x4, 3.5 gears( 20mpg).

 

97 auto and i get 20 average and 22 on the highway at 70

 

97 auto 13 mpg unloaded.<br>new air filter<br>set valves myself<br>need to get timing checked

 

1996, 6-Speed, 4.10 gears, 15mpg... new air filter, new fuel filter, haven't adjusted the vavles in a long time. Will when ever I buy a turn over tool.

 

94, 2500, 4x4, auto, 3.55, 219,000 miles I get average 20mpg driving 34 miles to work every day one way. If on a road trip I get 22mpg 24mpg if I keep it at 65mph. Haven't towed anything heavy enough to make a change in the mileage.

 

What kind of effect would altitude have on MPG?

Will when ever I buy a turn over tool.<br>[/quote]i just put a socket on the fly wheel, and turned the engine over till the valve i wanted to adjust had no pressure on it. I figured that it was on the round part of the cam, not being pushed on by the lobe of the cam. most of the valves where a little on the tight side.

 

I would do it that way if I could get to the flywheel without taking the tranny out. : I haven't even looked to see if there's enough room to put a socket on the harmonic balancer or anything. I was just waiting for that tool because it's about the only other way I know of.

 

he he he! Thats what I meant. So yes, I just put a socket on one of the small bolts that is on the harmonic balancer. It meant a lot of lying on the ground, turning it a little, then getting up to see if the rocker arm was loose. And you dont have to order that &quot;Extra special&quot; Flywheel turning tool.<br>Just my .02c
