Hi, I've got a 1995 Sub impreza wagon, with the 2.2 motor. I am runnin with a outback lift and 18inch rims. Dude, my car gets terrible gas mileage too. Maybe a 150 to 170 miles to the tank sometimes worse. Now that its winter I took the rims off and replaced them with 15 inch winter tires and installed a intake system, my car is runnin 220 to 240 miles to the full tank!!! Big diff..
