I had to drive an hour and half to meet beastman for the sale of my sideskirts. The night before, I filled up my car. When I came back...I was on empty. Almost dead out. It was only 180-200 miles put on the car during that trip. So today, I was thinking about the possible problems that could be contributing to my crappy gas mileage... The first thing I thought about was the O2 sensor. My car burns oil and maybe the residue was clogging up the sensor or something. I took it out, and here is what it looked like.





This is after I took a wire brush to it and cleaned it the best I could. The white charred marks were a lot thicker. Also, towards the base of the sensor (closest to the flange) was a thick black gunky residue that came off.

My question is, should this be replaced or would cleaning it help out? Or make it worse..?

Thanks in advance,
Steve

just replace it, they're like $35 from autozone for the universal ones(you'll need to splice one wire). Even if it's not the o2 sensor, that thing looks like it needs to go.

ok, i ended up cleaning it up really well. it looks new...

Do you think that this will help my consumption of fuel?

What other things should I check on or replace to help this?

ehhh, still replace it - it might look good but chances are that u probably have a fried o2 sensor on your hands or malfunctioning

cleaning it won't really help, it's the part inside that matters.
