Changed O2 sensor
Hey guys, take a look at these images. I changed my O2 Sensor today (Okay I admit it, I couldn't wait for NEBF so I went and bought the wrench.)
Is this how a sensor with 102k miles on it should look?

Looks very good... Almost like it has been replaced in the past... That engine was burning clean

With any high milage car that has an Original O2 you can bet that it has slowed some in its signaling rate.... we reccomend that they be replaced at 50-60K intervals too keep the effiency up... I have never had one that lasted more than 70,000 miles... If you gas milage was to take a sudden nosedive for no reason than the O2 would be suspect to failure...

My bonnie has 155k on it... is there any way to tell if the o2 sensor is the original? The guy I got it from says it'* all highway miles & doesn't remember if it'* ever been changed.
Over the weekend I took a little trip (110 miles) all highway, and got 27mpg.

My car was bought new (by me) and has 123K on it. I've never changed, or even looked at, the 02 sensor. .
The mileage hasn't changed a tenth since the day i rolled the car out of the dealership.

O2 sensors last over 70k all the time on the average car, and actually on the average car 90-110k is the expected life span. Changing them earlier as preventative maintenance is ok, just as long as you realize that youre more than likely to replace a good part. If your car has had some other problem such as a leaking down injector, excessive oil burning, blown head gasket, etc then you should expect your O2 sensor to last nowhere near as long. OBD cars are very capable of letting you know when to replace your O2.
