Can You Put Copper Grease On Spark Plugs? NGK does not recommend the application of lubricant such as copper grease to spark plug threads as the result is a reduction of frictional forces at the thread faces. It’s very important not to over or under tighten spark plugs during installation. Over tightening can lead to distortion of the spark plug and breakage.
What grease do you use on spark plugs? Dielectric grease
Dielectric grease is often used to seal the connection between spark plugs and spark plug wires. Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion.
Is it OK to put anti seize on spark plugs? Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch. Do not use anti-seize or lubricant on NGK spark plugs.
Should you put anything on spark plug threads? AC spark plugs should be installed dry. Do NOT use any type of anti-seize lubricant on spark plug threads. Anti-seize lubricants decrease the amount of friction between the threads, resulting in over-tightening. That can cause the spark plug to move too far into the combustion chamber (in crush washer applications).

Can I use lithium grease on spark plugs?
The grease that should be applied is white lithium grease. Dielectric grease is often used to seal the connection between spark plugs and spark plug wires. Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion.
Does Vaseline work as dielectric grease?
Vaseline can work as a substitute for dielectric grease, the big differences are that it can degrade rubber and plastics over time, and it’s combustible – but I’ve used it in the past on car bulbs, wiring and battery terminals and it hasn’t been a problem yet. Dielectric grease is silicone-based.
Can you use wd40 on spark plugs?
Using WD-40 to repel water from spark plugs, distributors, alternators, and batteries is a good way to prevent corrosion and keep moisture away. You can also use it to ease the removal of spark plugs, especially if there is any rust or corrosion.
How much does it cost to tighten spark plugs?
Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about ½ – ⅔ turn more with a spark plug wrench. (Taper seat: About 1/16 turn more.)
Is there a good substitute for dielectric grease?
Silicone-based Grease
Do you have to use dielectric grease on spark plugs?
Most commonly applied on spark plug boots, lightbulbs, and battery terminals, dielectric grease is, in theory, a protectant like car wax. It’s not required, but it could help extend and maintain the life and quality of your vehicle and its parts.
Should I use anti-seize on spark plugs in aluminum heads?
The nickel coating on most modern spark plugs provide added protection from seizing in aluminum cylinder heads and has made anti-seize less important in spark plug installations. Anti-seize can alter the tightening torque up to 20%, increasing the risk of breakage.
Where should you not use anti-seize?
When not to use anti-seize

Can I use Vaseline on my spark plugs?
Vaseline is petroleum jelly and is in fact electrically conductive. That’s why you use it in preference to other forms of grease. If your engine has the more modern ‘COP’ system (coil-on-plug) then lube the spark plug boot with dielectric grease, this helps prevent misfires and makes removing easier in the future.

What can you use white lithium grease for?
White lithium grease is a lubricant that typically comes in an aerosol form. It is a heavy-duty lubricant that is used for metal to metal applications.
White lithium grease can be used to:
Lubricate car door hinges.
Lubricate sunroof sliding panels.
Protect components from water ingress.
Lubricate motor pivot points.
Can I use white lithium grease on spark plug boots?
No, DO NOT use the white grease inside of the spark plug boots, the white grease is lithium grease!! Use silicone dielectric grease, which should be clear.
Is Vaseline electrically conductive?
Vaseline is petroleum jelly and is in fact electrically conductive. That’s why you use it in preference to other forms of grease. It’s purpose is to inhibit corrosion and fill any air gap that would promote ozone build up in the joint.
Is there a conductive grease?
846 is an economical, carbon-filled, electrically conductive grease. It lubricates, reduces contact resistance, repels moisture, inhibits corrosion, and prevents static buildup. Use 846 when you want a lubricating grease that provides great electrical contact and environmental protection.
Is dielectric grease and silicone grease the same?
Silicone grease, sometimes called dielectric grease, is a waterproof grease made by combining a silicone oil with a thickener. Other thickeners may be used, including stearates and powdered polytetrafluorethylene (PTFE).
Why is there oil on my spark plug?
You may find oil on a spark plug because: Too much oil was mixed with the gasoline. The piston rings (the component that seals piston and cylinder) are failing. If valve stems or valve seals are worn, oil can slip past them into the cylinder and coat the spark plug.
