My 90 Accord EX with a 4 cyl, auto trans and 120,000 miles. On a good day (Highway) it gets 23 MPG, is this average/good/bad? I have replaced the oxygen sensor, throtle position sensor, speed sensor on trans, coil, wires, plugs, air filter, fuel filter, had the carbon cleaned from the EGR intake, plus I can't see it smoking but it goes through a quart of oil every 1,000 miles. Any ideas why?

 

that is what I get driving in the city.....I get near 33MPG on the highway

maybe try cleaining your Fuel Injectors and then after that reset the ECU

 

What there are a lot of variables that you didn't answer. For instance, how fast were you driving, and how are you tire pressures?

That is very low if you were driving around 70mph. I get around 37 miles to the gallon highway traveling at around 80mph, and 26-27 city. I've got a 93 EX w/ 152,500 miles. I'm burning a bit of oil every 2000 miles, no biggie. As stated you might also want to clean your injectors. If you can get your hands on some BG44K do it, you WON'T be disappointed.

 

Thanks everyone I will try cleaning the injectors.
