I drive my mach quite a bit. About 60hwy 40street. on average im getting about 17mpg, just last night when i took a long drive (20st 80hwy) I only got 18mpg... WTF?
I had an OR h pipe on it and went back to the stock midpipe and magnaflows thinking it was the OR h pipe that was giving me problems (engine lights come on and off etc) but it did nothing. :nonono:
all the 02 sensors are fine, as far as i know the car isnt tuned (or else it probably wouldnt be throwing check engine lights with the OR pipe).
any ideas what it could be?? I dont beat on the car much, just on ramps etc. i set the cruise control at 70 when im on the freeway and still get this crappy mileage.
WHAT GIVES?? im averaging 220 miles per tank!!
