v6 10 mpg?
Moe in Wichita Kansas
On Nov 15 bought a 01 dak, V6. I had to put cap rotor wires on it. dont know condition of plugs. It has a auto trans, 3.55 gear. It moves out lots better than the 99 i had. it got 13 - 14 mpg. the 01 only gets 9-10 mpg. how ever i do have a heavy foot. is this mpg norm?

try putting a set of NGK v-power plugs in, bad plugs seem to make a big difference in mileage in the 3.9's. the next thing i would recommend is taking off the air intake, removing the throttle body and completely cleaning it, that also makes a big difference. also, a lead foot REALLY reduces mileage on 3.9's. my truck can get 10 mpg if im really on it all the time or 20 if i take it easy all the time.

if you go light on the gas pedal and you still get crappy gas milage and nothing else seems wrong with it you might want to check the fan clutch. My friend had a first gen dak v-6 that was only getting like 11 mpg and we found out that the fan was not shutting off and the fan clutch was bad. when it goes bad it stays engaged and drags on the belts causing low mpg. Your 9-10 seems very low, seeing as my 4.7 v-8 gets 19-20 highway
