This time of year in town I get 9mpg and like 14mpg on the highway....

Gotta love the winter-blend crappy gas!

Averaged 15.7 yesterday going out to Greensboro and back, probably 100 miles or so.

190 miles, 70mph temp was 50-60F

i just bought my truck and was hoping to get around 15 to 16 mpg, but i think i am getting 13 mpg, would definetly like to get 16 or 17, i need to do a tune up, but does anybody have any other advice to improve gas mileage?

Keep up on all your maintenance, properly inflate your tires, take it really easy on the go pedal. Also don't lift or put bigger tires on the truck is fuel economy is a concern.

I dropped in a k&n air filter and got a little over 20 mpg mostly interstate or open hwy. Polly 15 miles in the city

If you dropped in an OEM paper filter you would have gotten the same result, without the dirt and oil into your engine.

If the K&N filter is charged right, you won't get it's oil into your engine. I've seen them after people clean them, then over oil them and then the oil can screw up the MAF and cause some poor running.

I used to like them, but when I saw no benefit I went back to high quality paper filters. They are cheaper and you don't have to worry about over or under oiling.
