about 18 in the city 22 on the highway, with 170 horsepower and 400 LB FT! all stock cummins, hopefully after a K&N it'll bump it up a bit.

 

i got a 318 2 bbl stock drivetrain and 32 inch tires... i get like 7 in town and arount 8 or 9 on the hi way. i used to get like 12 to 14 with p235's.

 

With my stock 85 D150 Ram(318, 3 speed a904) I get 10mpg city(driving hard) and 14mpg hwy. I do have a rebuilt longblock 318, but its all stock with exception of the k&n filter and ignition(wires, plugs, mopar performance cap and dist).

Note: I am probably the only one running stock hubcaps and tires. http://www.cardomain.com/ride/570246/2

 

Most recently I have been forcing myself to be light footed($3 a gallon). Results:

15.4 mpg hwy when cruising at 65-70mph(i love cruise control).
Havent calculated city [:@].

 

1992 D-350 Cummins with 4.10
15 City/17 Highway

1985 D-100
2 Drag Strip/0 Jackstands

 

With the new TCI transmission and non-lockup torque converter, the mileage has actually dropped. In my GVX, my Mom drove it one day and I got in it on the next day. When I left home, the computer said the avg. was 25 mpg. I drove 10 miles, and it dropped to 16.7 mpg. It made me wonder how I still have a clean driving record.

 

hey i got the stock hubcaps and maybe tires on my 88 318. and my truck's a retired CHP cruiser[:'(]
i also spend the least amount of money for gas since its not even running yet

 

Hi All

Just bought my 84 Ram 100. a 318 rebuilt motor with racing cams (2BBL Carb) and a little over 1000 miles. 4 speed manual trans , dual 3" pipe with glass packs and Hoosier tires. No polution equiptment nor cat what so ever. Red with bench, radio, crank window and that is about it.
I got an average of 9.8 which included town and highway.

Had wiring issues and she is back up!!!
During the fix put on new distributer, wires and Hi pro coil.
Very sweet truck for what i paid for it. Needs rear brakes redone and parking brakes. Only cost me 1500. I will have put in 300. more and it whould be perfect.
very satisfied. Same carb as my 83 AMC Eagle.
Did I say body was re-done and painted a year ago...no holes nor rust. New exhaust, new clutch on the manual OD transmission, I guess I said that already.
My gas milage figgures may not be that accurate as they are not stock sizes and my odometer may be off..

Had carb issues and will replace with a Holley. Then I'll see what milage is...
