Do I need to replace O2 sensors no codes 134k miles
Do I need really need to replace oxygen sensors when no codes but mileage at 134k miles? Fuel mileage has been the same for years. It's about $440 for the 4 sensors from fcpeuro. Wondering if this is a worthy preventative maintenance or just hang on until they fail or throw codes. I don't think O2 sensor failure would be catastrophic.

Thoughts?
