new O2 sensors will IMPROVE fuel economy?

Hi folks!

Mmmmmmm.....
So new O2 sensors will IMPROVE fuel economy????
My 1992 I-4 has 150K on it and the sensors have never been replaced.

Would I just waste $$$ on getting new ones?

Also where is a good place to get em?

I replaced mine and got a little better MPG. I think it helped around 2MPG, so its worth it over the long run @ $30 per 02 sensor.

02 sensors usually tend to become less efficient after about 75k miles. Seeing that your at 150k, I'd replace them if I were you.

I got mine at NAPA.

Are they easy to replace by someone who has little experience?
