Hello,

First time posting but I hope you guys are willing to maybe point me in the right direction. Basically, my civic gets roughly 150 miles per full tank. Which is definitely not good. I do drive a little harder than most because I am a delivery driver, but I still keep it relatively modest. I have replaced the timing belt recently as well as the water pump, spark plugs, radiator hoses, new air filter, and oil change (didn't do filter however). I am not leaking any fluids at all either. I am just wondering what else I should replace or do to try and increase the gas mileage.

Any help is greatly appreciated.

Thanks

 

It could be a myriad of things, but if it's driving normally, my money is on a bad oxygen sensor.

Other things could be a clogged fuel filter, sticking brake caliper, bad wheel bearing, clogged catalytic converter, or the timing is off, but the car would be driving pretty erratically if any one of those had failed.

 

Thanks for the quick response. I already plan on replacing the fuel filter and oil filter and possibly new wires and cap and rotor. So new O2 sensor is where I should start you think??

 

Is the CEL on?

 

Best really nice post. Different and useful
