1999 Honda Civic XL, 106000 miles. Have taken good care of vehicle. Constant oil changes, filters ect. Have recently lost gas mileage, about 6 to 10mpg. New spark plugs, increased power but nothing to gas mileage. Vehicle runs very good. Maybe o2 sensor? Also great site, lots of information.

I wouldn't mess with the O2 sensors yet. They can be a factor but there are other things to look at. Timing, tire pressure, dragging brakes, air cleaner, etc
Good old basic stuff.
