O2 sensor cleaning.....no codes, worth cleaning

2010 DCSB Sport, 218k
No engine check light.
Worth cleaning to improve fuel economy?

 

No. Why fix something that isn't broken?

 

Not sure what there is to clean, you’ll likely damage it by trying so. If it’s working leave it alone.

 

Don't touch them. Only thing that would ever make a difference is replacement with OE parts

 

Those who have successfully cleaned the cats per the oxalic acid/citric acid wash and also tried the sensors with the same stuff say no.

 

Leave them

 

Why is my post # 2 backwards?????

 

April 1st. The mods have pulled one on us.
All mine are backwards and upside down. But it’s only you that sees your own post backwards.
PMs are the same also.

 

Now they are all crooked. Lol.
At least I can read my own post now.

 

I also drive a 2010 v6 mostly stock except for duratracs tires stock size tho. And i get anywhere from 17-20 mpg I would clean your throttle body and MAF sensor if you’re looking to improve mpgs it will help a little and keep it under 70 on the highway for some reason our trucks drink the gas over 70 on the highway

 

Yup, thanks.....have done all that, including spark plug change, PcV valve, fuel injector cleaning.....
Drive to work, once a week Houston Dallas RT....speed limit is 75 in the slow lane.....the extra 5mph is costing me 90 Miles in Range....
