Changing the spark plugs.....

On installation, I dab the tip of a finger in some anti-sieze goop, and make a single swipe (perpendicular to) across the threads before reinstalling the plug.

In 55 years of changing plugs I've never had one back out, nor require more than a gentle push on the ratchet handle to break it loose. (And, once the initial torque is broken, the plug usually unscrew with twisting the extension with my fingers...usually.)

Obviously, those threads didn't strip out; no harm done. But, I know you'll like the anti-sieze when you remove them next rime.

Yea, when I went to undo I said much more than YIKES!.....one of the PO's really wanted to make his strength known in the future.....I have used this size breaker bars enough to now have the feel of how much pressure to apply when getting something loose. As mentioned, I wouldn't do this to another owner's vehicle even if asked....if I mess up on my own vehicle, oh well!!! but as you can see, they came out fine. I did use a slight amount of anti-sieze for the next time....

I have never used oil for this purpose, not saying it wouldn't work....and have not performed a snug-up on the plugs, yet!!!

Anti-seize or oil works well on plug threads but if you use anti-seize compound you MUST use non-metallic anti seize.

Much of the anti-seize on the market has copper, moly or nickel in it so read lables before you buy.

My favorite for spark plugs is DuPont Krytox a flourinated grease which has anti-seize properties and is very durabile at high temperature.
