Is nickel based neverseize the best all around compound or is the copper based good enough for most applications?


elroy, i have always used neversieze on sparkplugs with no problems......
Any time I pull the plugs from a car with Aluminum heads and it has anti-sieze on the threads I say a thank you to the guy who did it before me.

elroy, i have always used neversieze on sparkplugs with no problems...........why do you say not to?............![]()
It acts like an insulator and changes the heat range of the plug, heat is conducted from the spark plug into the metal of the cylinder head and the neverseize insulates it from doing that and it can get too hot and you can get pinging or detonation. There are numerous TSB's on this, follow mfg's instructions.
I always use a drop of motor oil on the threads. Remember don't overtighten and on aluminum heads you should let them cool before you take them out.![]()

paying special attention to thoroughly coating the electrode.
Tell that to this guy:
Maybe the genius who figured out that never-seize could bump the heat range never realized the heat path in through the seat. The technical service bulletins are also written by the manufacturers who assume you're screwing OEM plugs back into the head.
It comes down to having a little common sense about it. Just slap it on there good and thick.
Elroy's statement above was made in jest. In my humble opinion, you'll play hell bumping the heat range enough to cause detonation by using a little never-seize. Sure slop it in there real good and you might have some issues. Ignore it and you'll have some issues too as post above.
If it's alright with you, I'll use it
Elroy would venture to say to kind of depends how critical the application is as these lubricants were developed for specific reasons.
What ever you do don't use it on spark plugs. That is unless you have a Porsche. In that case, lather in on heavy paying special attention to thoroughly coating the electrode.
Wouldn't want to upset the heat range you know.![]()
Not only that, it's unnecessary on many modern plugs. The torque spec is dry not oiled too. Many manufacturers, Bosch, for example, put a coating on the threads at the factory and specifically state not to use any additional anti-seize. If you are taking the plug out and putting it back for some reason, different story but the initial install requires no anti-seize for many plug mfgs. Check first.

I have never heard the nickle is "better" than the copper. Different applications. As far as I know, the copper is more expensive and harder to find. I had to resort to Wurth Copper based anti-sieze.
Those are my plugs in Elroy's post. The straps are not melted. They are eroded from normal wear and the ******** the bottom plug is broken off on one side, due to the displacement of the porcelain core by the pusher tool.I use it quite a bit. Elroy, the plugs you posted a pic of are out of a 3 valve mod motor. They are notorious for breaking like that and Ford has a tsb telling you to put antiseize on the plug all the way down to the ground strap. Yes I did see that the ground strap is melted.

The Ford TSB specifically says to use a hi-temp anti-seize only on the smooth part, below the threads and above the strap.
I don't think a small dab on the threads would hurt a thing. I didn't do the threads on mine because the threaded portion came out clean as a whistle on all of the plugs. It was those damned crimped-in lower shanks that caused all the problems.Looked like the bottom one was melted, my bad. I know the TSB calls for below the threads but I antiseized the threads on mine when I installed my HTO's. I prefer to do that with all the spark plugs I install in aluminum heads, just a personal preference. Never had a problem so far.

We use a lot of pure Bostik Pure Nickel Special Never-Seez though. I've used it on CFM56-7B engines, as well as RR/Alison T-56s.
When you say resort I take it that you had an issuer with Wurth, if so please pm me and I will resolve your issues.
As far as antlered Wurth offers quite a few different flavors
A few of my favorite are
NI 2400 - nickel anti seez
Cu 800 - copper anti seez, tube,can,aerosol
Cu1100 high adhesive copper anti seez
Cu1800 alum anti seez (never seez)
We offer many other types, those are a few of my
Favorites.

"Nickel" is better than the general purpose Permatex 133A stuff in the hardware store?
I think 133 says you can use it on spark plug threads- Nickel too?
I understand you never want to slather it on thick so that it drips onto the tip or puddles around the bottom in the spark plug well.
Absolutely not. My response was poorly worded.
I have nothing but praise for Wurth products.
I have the Cu 800 I believe. I bought it to use on Mercedes wheel/hub interface to keep them from sticking. Also to coat battery terminals.
Colby, please let me know if I purchased the right stuff.
I use it on everything

Piss poor?
Piss this response from Elroy and take note that some of these responses have flat out tickled the hair up Elroy's ***. In particular this smart mouth comment:
Elroy suggests that nate379 tongue Elroy's bag. He is also cordially invited to seconds on both Elroy's crack and mine. You see sir, you have pissed me off.
For the the others who have read past this little ***** parade, Here is how Elroy views the issue of never seize on spark plugs:
Use it
Use it smart and tell others to use it. But use it in the correct way
For those who claim Never-Seize elevates the the heat range of the plug that is true in limited cases only. This over heating condition is primarily associated with using copper based materials in aluminum cylinder heads. In the correct conditions, the copper can set up galvanic corrosion with the aluminum and generate an oxide that will in fact act as an thermal insulator. This condition can easily be eliminated by selecting a lubricant free of copper. In the far majority of cases the never seize will actually help the plug draw heat off the tip.
As far as plug tip temperature are concerned, there are other more important parameters that enter into the picture beside the fact that one chooses to use anti-seize or not. The main factors being the design of the plug itself and particularly the heat transfer coefficient of the ceramic and length of the heat path. Also note that the far majority of the heat transfer occur through the seat of the plug, NOT the threads !!!
In addition to these basic observations you also need to look at this issue from the manufactures point of view. The first thing to consider is the fact they are screwing together new parts and could give an "Elroy's ***" about the service aspects. Their goal is to assemble the machine as quickly as possible
The additional expense, labor and potential liability associated with a proud and skilled UAW member manually applying never-seize to a million spark plugs just won't cut it. But have no mistake, the benefits of a "wetted" heat transfer surface is proven. Be that wetted with a liquid or as a metallic coating that applied to the plugs threads at the point of manufacturer that cold flows. The problem is that used components (cylinder head threads) are worn and will not perform as well as new. Thus the need to apply the correct formulation never-seize when in a service environment.
But there are reasons the manufactures recommend not using never-seize compounds. First off is the potential corrosion issues. The second issue concerns the torque. Never-seize is going to reduce friction and depending if the lubricant is applied to the threads only or all over makes for problems of recommending a torque difficult.Then there is the problem of ******* Elroy slopping it all over the insulator. That's a no-no for obvious reasons.
So as a result the manufactures take the safe way out and simply say don't use it.
Is the use of never-seize out dated ? Not even close.
You just keep right on telling yourself that as you enjoy your seconds *****.
The problem with anti-seize has nothing to do with changing heat ranges. The only issue you would have is if you used copper anti-seize on a vehicle that has an ion sensing system. If your vehicle is computer controlled but has no cam sensor it uses ion sensing to determine what phase the engine is on. Ion sensing sends a small voltage signal (I’m pretty sure it’s under 100 volts) into the combustion chamber to determine if a fire (combustion) has just occurred. If the combustion event just happened the resistance will be different so copper may affect the resistance of a spark plug. Spark plugs should get silver anti-seize only.![]()
