Fox Just a quick question...

How long do oxygen sensors last ?
I've had mine on my 1991 mustang lx coupe 5.0 since 1991 and have never been changed I only run 94 octane gas do you think i should buy new ones from lmr I've got 240,000 kms on her with mac 1 5/8th long tubes with a hi flow mac h-pipe with cats.

Hard to say. Depends on what sort of conditions they've seen over their lifespan.

At 150K miles, i would replace them with some motorcraft units for peace of mind.

If you cannot find a motorcraft, the ONLY aftermarket oxygen sensor I have had any luck with is Bosch...

you'll pay more for stuff like common replacement parts there, go to rockauto and find some motorcraft or bosch.JMO
