Changing out a failed O2 sensor on my wife's 2015 and the service manual says to use anti seize compound. My 2020 Frontier manual doesn't say that. Every other O2 sensor I've changed never got it either. What's the general consensus?

I'd use antiseize. Backoff the tightening torque to about 80% of spec.

Yes to antiseize.

Seized a can of Permatex antiseize. Now waiting on sensor to show up. Thanks All!.

My new O2 sensor came with anti seize on it. Cool. Reset the ECU and logged a long run with Torque Pro. Voltage looked within standard so I'm calling it fixed!
