My brother put new spark plugs in my car but he didn't use the 2 packets of lube from the guy at autozone that gave them to me.....is it necessary to put this stuff on? My car has 65,000 miles on it...we changed them because my cars engine light came on and he hooked it up to his computer and it showed it misfired in 3 different spots.

Well that stuff they gave you is called antiseize and it basically keeps the spark plug from welding itself to the block of the motor. Its a good idea to put that stuff on makes them easier to remove in another 65k

thats anti sieze... not required.you can use it... i dont.

the lube just makes it easier to get them out the next time you replace them

Do it over and put it back on.==== DETAIL ====The stuff is called anti-seize. It is not lube. Lube just makes it go on easy. Anti-seize is designed to make it come OFF easy. Lube don't last 50K / 5 years. Anti-seize is design to last till you take it off (sometimes 5 years)Modern cars have aluminum heads. They are fairly soft metal. It is possible that you can damage the threading on your heads later when you try to remove the spark plug.====Why it misfires is another question.===Don't forget to vote for the BEST ANSWER - please - whoever it may be.FACT: You also get +3 points when you vote for BEST ANSWER

if you never push you car all the time (abuse it) then you dont need any of that fancy stuff. Its like all TV ads nice to have but you dont need it.

not critical, but helpful. it is helpful for three things-it makes installation easier, if you use the old "rubber hose method" in which you take a piece of appropriately sized radiator hose from your local auto parts store and force it over the top of the porcelain insulator of the plug, then carefully thread it in by hand to ensure that it does not crossthread. The anti-sieze will make it much easier to install this way.If he did it the "old fashioned way" in which you turn it to a quarter turn past tight, then it makes no difference. If he used a torque wrench, then the anti sieze will produce the correct torque reading, and dry will not. However, this is not a big deal, as long as they're all "pretty tight".It also makes sure that corrosion does not form on the threads, causing them to sieze and become difficult or impossible to remove. I have never seen this problem develop to a level that I could not remove the plug, however, the threads will not be as smooth and clean as they originally were.Basically, do it next time, but ur pretty much OK.Hope this helps,Joeto Henrysol: for christs sake man, THE PLUGS THREAD INTO THE HEAD NOT THE BLOCK! the head can actually be replaced easily but expensively, the block, not so much.

short answer... no.... and the missfire is not from the plugsi have been an auto tech for over 10 years and have never once put anti seize or dialectric grease on them, and i have never had a seized spark plug cause by me, when you have a service done on your vehicle they remove the spark plugs, or at least supose to, this breaks the carbon ring that has built up on the spark plug. auto zone/ advanced or any other automotive store sells you that stuff because it makes them money kinda like the little felt rings they sell you for a battery. My rule of thumb is if the factory didn't do it i won't either
