I just bought a 02 3.9 qc and I get 14.5 to 16.5 thats it......................[:'(]

 

I get about 15-16 in the city.

Seeing how I have 190 thousand miles with very little work done to it, I think its pretty damn good.

 

Just took my '06 Auto ext cab 4x2 from DC to New York and back. Set the cruise for 75 mph with about 4-500 pounds of weight in the bed and averaged 19.7mpg according to the gauge. Not bad I think considering all the hills through Penn. keeping it at 75.

 

I been getting 18-19mpg city and 23-24mpg highway with the 07' [sm=smiley20.gif]. The 93' was avg about 16 mpg all the time unless you were pounding people off the redlight and then it went down around 12-13mpg [sm=smiley21.gif]

 

My stock 02 QC 4.7 automatic is averaging only 14MPG. That's what the digital readout is saying anyway. It's not really stop and go....some long straights at 60mph but for the most part, some stop lights. I don't mash on the pedal either. I actually try to keep the RPM's at 2K or under. Just changed the oil to full synthetic too. I've been thinking about a cold air intake....any suggestions on what kind? I would think you can't go wrong with K&N.

 

around 17 mpg's with about 50/50 highway and city driving
