I have a 2006 GT 5 speed 'Vert. Now my car has 150K miles on the clock and runs as good as the day I picked it up new. Now here's the question, should I replace the O2 sensors? Performance is great, mileage is the same as it's always been. Should I spring for new ones?
I see 2 on the pass side and one on the drivers side. Any suggestions?

 

Really? No thoughts?

 

If it were mine, l would with that mileage. If you do, ONLY use Motorcraft, any other will likely cause issues.

 

Is your check engine light on? If not, no need.

 

Nope, no CEL

 

dont try and fix what isnt broken. if there was an issue with the o2 sensors, you would be flagging codes, or your mileage would be tanking

 

I wouldn't replace them for sake of replacing them. That's like replacing a catalytic converter for no reason other than mileage.

O2 Sensors are no more a maintenance item than the valves in your engine are. Replace the 02 sensor only if/when needed.

 

Thanks guys!

 

I have an '05 GT in Screaming Yellow. I thought, with no foundation, that Screaming Yellow was an '05 color?

Mine looks like new, no joke. Is garage kept. Just wanted to give you a FYI FWIW - I've been using Eagle 1 wash with the Nano wax in it, and the Eagle 1 spray on wipe off Nano Wax product for the last few years. Positively glistens. I have used other products over time. I do use the "quick detailers" at times. Can't recall the last time I used a paste/liquid wax that you wait for it to dry before removing. I am sure its been at least eight years.

 

DK, but Screaming Yellow was on my window sticker of my 2006 GT 'Vert
