O2 Sensor lifetime?
There is a mention of ensuring that 02 sensors are changed at the recommended interval but I do not recall ever seeing that interval from Ford, or for that matter specifically written for any car.
I prefer to change parts only as they're needed, but again there is a lot to say for scheduled maintenance.
What recommendations have you read or been told of, or what is your own experience?
Thanks!
as to shop time and milage i've seen trucks with over 100k and still running the oem part.
