Thanks Guys, I started here last fall with average of 29-32mpg and achieved best tankfull last week and hit 39mpg in my old civic This week i have been driving to and from hostpital 2-3 times a day and had to make quick transit times driving normal speeds and keeping up with traffic in city and out on interstate highway Lowered my FE back down to 30mpg Good thing about loosing my FE = I got to push gas pedal to floor, blow out the cobwebs and actually see how fast my civic willl go (not bad for a little 1.5liter)
