1988 dodge mini ram van 3.0 auto w/o over drive I get only 13.6 mpg the best I got was 15 mpg have had the van 3 yrs it now has 151000. and still runs good. have had new fuel filter, rebuilt fuel injecters tune up new radiator installed was told the reason for only 13.6 was the 3.0 with out an over drive trans. could that be the problem.or is there somthing I'm over looking sure could use some help on this as the gas price is killing me

 

Wow! i'd be trading that one off. I've got a 1989 Caravan with the 3.0 No Overdrive and i'm getting about 25 on the highway. Wish I had some suggestions for ya other than trade it off but I don't. Good luck Hopefully someone on here will know a few tricks.
