Fuel Mileage or Lack There Of
Hey all, I'm a new member and let me say, impressed with the info swapped on this site. I have an '02 SE that has been mine for about a year and a half. I got it with 33,000 miles and it now has 94,000. My commute is a 100 mile round trip on the interstate with the cruise set at 80. My issue is that on a tank with that commute I average 22 MPG. Recently I made a trip to Oklahoma and tore up the highway, no cruise, speeds up to 90+ and got almost 30 MPG. What gives? The only problem I've seen with this car is an occasional "Service Engine Soon" light with an intermittent stumbling of the engine, but I think that may have to do with my fueling technique. Thanks in advance.
