warrrior- it sounds like your car has issues or some gears you dont know about - should get 25-26 mpg on the highway with stock.

 

I'm just gonna say I only get about 15.....

 

well i would say 23 or 24 on the highway for me. warrior i would do a complete tune up; plugs+wires, fuel filter, air filter, pcv valve, egr valve, get all tires at proper pressure, o2 sensors, and check for exhaust leaks too. Then see if your mileage doesn't get better.

 

all right,

thx guys i'll try your recommendations and let you know if mileage improves...
