Did a spark plug change last week using some aluminum-containing anti-seize on the threads. Today I read the only copper anti-seize should be used. Some even recommend no anti-seize because it leads to over-torquing.

My question is whether it's worth the hassle of taking out the plugs to clean off the aluminum anti-seize and replace with copper stuff or nothing at all. Has anyone used the aluminum stuff and had no problems with the plugs fusing to the aluminum head a year later? I hate to go through the process all over again.

Did the past cars have aluminum heads? That appears to be the problem because similar metals can fuse after prolonged contact.

You'll be fine, as long as you put some sort of anti-seize then your okay. The only purpose of anti-seize is for aluminum heads so your good, no worries.

My past 3 cars have all had aluminum heads and I have always used the standard silver anti-seize and have never had fusing issues.
