Replace O2 Sensors
I have a 2000 3.0 with almost 110K. I'm just curious what others would do. It's probably time to replace the 2 front O2 sensors. Vehicle passed emissions test 2 months ago and runs good. What would you do? I'm leaning towards waiting a little longer to replace mine.

According to Delphi, who claims to make the longest lasting O2 sensors, they say replace them every 150,000 miles. I'd say replace them every 100,000 miles to ensure optimal fuel economy and prevent the costly damage that can happen when they fail. Realize on your 2000 Ranger 3.0L, that the catalytic converters, which are just one component that can be damaged by failed sensors, cost well over 1200 at the dealer. You can get them cheaper elsewhere, but not by much. And lets do a hypothetical scenario. Lets say you get 20 mpg with a good O2 sensor. Now lets say one that has started to go out is causing a 3 mpg lose. This will cost you over $300 dollars. Since 10,000 is the national average for how many miles most people drive per year, this means that even if the bad O2 does not damage to other parts of the vehicle, it will cost you over $300 per year if fuel prices don't increase further. To me, its a no brainer. Changing an O2 sensor is not unlike gambling. You know you are running on borrowed time, but you are tempted to see how far you can stretch the mileage of that sensor. As the sensor ages, its voltage output will decrease, and the computer will detect that drop and will increase the amount of fuel it adds to the engine until it is satisfied. Low voltage tells the computer that you are running lean, when in reality, the low voltage also indicates a weak sensor.
Take it from someone who sells catalytic converters for a living. I sell more catalytic converters if no one ever changed the O2 sensors till damage was done. But I don't want to see you guys end up spending more money than you have to. The people on this forum are almost like family. I don't like to see people spend hundreds or thousands of dollars on a problem that could be avoided with simple maintenance.
