What brand or what kind of anti-seize compound is primarily good for exhaust bolt thread and o2 sensor thread and also majority of bolt thread on the car.

Any high temp kind is good.

copper or nickel?

loctite anti-sieze. I use it for my o2 sensor and the manifold-to-midpipe bolts and no problems so far

^yes

I personally use nickel kind, I use it on spark plugs. its good.

not sure about O2 sensor tho. maybe I should take it out and apply some.

Thx guys for advice. After spending some gas and mileage, I bought the Permatex Nickel anti-seize compound. It's the highest temperature rating (1315degree celcius) compound that I can find. Even my dealership doesn't use that high rating.

the nickel Permatex is the best, but any is better than none
