MPG Dodge Dakota
1990 Dodge Dakota 4x4
v6 3.9l
I currently get 15.5 to maybe 16 on highway 65to70mph
I have done the following things:
Changed spark plugs
Changed spark plug wires
Changed oil to AMSOIL synthetic
Changed air filter to AMSOIL oiled foam filter
Make sure tires are at factory spec air pressure
Anyone have any suggestions on how to get a little better mileage? The check engine light has been on since I bought it. With the 1990 model the repair manual says it must be taken to a dealer to be scanned to turn it off. Could it be the O2 sensor that is bad? Any suggestions would be appreciated.

Find the cause of the check engine light.
Fuel mileage seems about normal----check the original EPA estimates to use as a guide.

You should be able to pull the trouble codes yourself. See my "The Basics" below and www.batauto.com
Some early Chryslers have a box which will light up and stay lit and must be disconnected or replaced to "reset" the maintenance lamp. But, this is a check engine lamp. There is fault in the emisison system. Autozone can also can your codes for you at no charge as well.
The mileage sounds about right. You are dealing with a 13 year old pickup truck with likely a LOT of miles
. 20 is the BEST you could hope for when new, and even that was an estimate .
