O2 Sensor Regular Replacement? 900 1994

posted by  someone claiming to be WhiteFox on  Sat Aug 23 04:18 CST 2003 [RELATED]

A Parts company I found recommended on the Brickboard site recommends regular replacement of the O2 sensor. They say it should be considered a "regular tuneup part" just like spark plugs and distributor cap, and should be replaced every 50K if you car is made before 1990 and every 100K if made after that. I have 150K on my 940 and the sensor signal is still swinging from .4 to 1 volt like the manual says it should. Replace anyway?
Thanks!

    Well they would say that would'nt they. And Jiffy lube try to convince us that all cars should get new oil after only 3K. They even put a 3K label on my V90 windshield even though the spec is 10K and 5K for severe duty driving. BTW I always stand and watch them after giving them my own Mobil 1 synthetic and Mann filter. They charge about 10 bucks.

    I think 50K is a bit excessive. I had an 88 740 that went 272K with the original O2 in it. It still swung from .2 to .8 quite nicely. Replace the O2 when it goes bad or gets lazy.
