Default 95 civic ex MPG too low

I have a 95 civic ex 5 speed and I just did my mpg and it seems that Im getting 17mpg in city and that is like normal driving not racing or anything, Im throwing a cel for oxygen sensor, could that be the whole problem?

yes, that is the problem, buy a good quality replacement sensor.

Do you have any CEL codes? Lets not jump to conclusions and start buying O2 sensors. Try replacing the fuel filter and other basic maintenece parts like plus, wires, cap/rotor.

Common problem, just replace the O2 Sensor and be done with it. It's not that expensive, and not hard to do yourself.

Well I will do that tomorrow, and then i will check the gas mileage, the o2 sensor is just the one that goes on the headers? or are there any otthers?

Start with the O2 sensor, buy a Denso or NTK unit, stay far, far away from Bosch.

yea you should only have the one. it'll be quick easy and not too expensive just don't break it.

oh and its header singular.

id say its a pretty safe bet that your bad o2 is making your mpg bad as well.
