I drive a 95 honda civic hatchback and being 11 years old this thing treats me well. Still shifts smooth, no tears or rips in the interior, rust free, and it doesnt burn a drop of oil. I have a question that has been covered before but i have done all that i know. My gas milage when i bought the car 2.5 years ago used was around 440 miles to a tank. That equates to 36.97 mpg or 37 just to round it up. That lasted for almost a year and i noticed a steady decline. 420, 380, 350, and it evened out at about 315 a tank. So that makes my gas milage at 26.4 mpg. So this is about the time gas prices sky rocketed, so of course i tried to do some refreshing to my fuel system. I replaced the plugs, wires, air filter, even new tires because was kept going flat. Nothing happened to my gas mileage. Still around that 315 a tank. Now all of a sudden in the past month i can't even hit 240 miles to a tank... which is just barely 20 mpg. So over the past 2.5 years my gas milage has dropped 17 miles per gallon. That means a total loss of 202 miles per tank. It kills me in the wallet area. My civic is now reduced to a fucking pig. This think hogs more gas than my first car which was a 1989 v6 thunderbird with a whole shit load of mechanical problems. What could cause this decrease in gas milage? Should i try a new O2 sensor?, fuel filter?, or injectors? Should i buy new parts, or go to a junk yard and try them out first? Any info will help out, thanks for looking
