Do you have to use anti-sieze on new plugs

[sbbamafan]

I planned on changing them in the morning but forgot to get any. Is it really necesary since we change every 30k anyway. I think it is only needed on the 100k type like in my wifes honda??? If I really need it I will have to get my car too hot tomorrow and change another day...

I didn't use any. Plugs are coated Steel and block is Alluminum. Chances of those fusing are very low. But, antiseize is a cheap insurance, if you worried use a light coat. Just use a torque wrench to tighten plugs.

You're going to find differing opinions on this.

If you're changing every 30,000 miles then you shouldn't have any problems without anti-seize. However, if you are changing every 5 years then you might feel better about using anti-seize. Breaking loose 5 year old plugs in an aluminum head is not a good feeling.

One needs to be careful not to get the anti-seize on the spark gap surfaces or body of the spark plug. Anti-seize is a thread lubricant so be careful not to over-torque. Use a torque wrench if unsure.

I do use anti-seize on plugs (as well as other bolts that I might later service).

I'd always use it since it's better to be safe than sorry.

It doesn't really add to the cost or effort of the job so definelty do it.

Absolutely agree. And as everyone else has already said, use the torque wrench to be sure.

Speaking of Never Seize, any idea where the Copper and Aluminum is coming from in some folks Used Oil Analysis? :bonk: That's why trending is so important. Anyway, I didn't mean to hijack the thread, just wanted to share another potential source for increased wear metals since this product was being discussed.

DO they, anti-seize" comes in different color? which one to use?

yep, the two seconds is worth it. Should be used on lots of bolts.
