Recommendations for Dielectric grease ?

I want to buy Dielectric grease as preparation for the next spark plugs change, any recommendations for a specific one? I searched in e-bay and found many types and brands!

As long as you are convinced you can trust the quality of the brand name, I'm sure any will do fine.

Permatex is commonly available at most stores in my area, used it many times and never had a problem.

Yeah Just go with any quality name brand. Its not an expensive product by any means so beating yourself up for a difference in price of $4 is kind of pointless.... spend $10 on a big tube of the name brand stuff and call it a day. One tube is pretty much a "life time buy" unless you're a mechanic that uses it daily.

FYI, I use Permatex dielectric tune-up grease, part number 22058.

My local autoparts store carries it... but its $9.26 on Amazon. I've done 5+ tuneups (one being a 16 plug hemi ) and have replaced a bunch of sensors for friends/family.... still have over half that tube left.

I recently had to replace my headlight bulbs and bought a small packet of the "bulb grease" for them at the same time. I figured a similar grease would be something good to use as I'm replacing misc electric components on my Commander. I recently replaced the Leak Detection pump and the Vapor Canister Purge Valve and figured I could have used some dielectric grease on each of their wiring connections. So I picked up a tube of the Permatex Dielectric Tune-Up Grease and also a can of WD40 contact cleaner.


Would there be an issue using either of these on the PCM?? I was going to disconnect each of the connectors on the PCM, spray them up with the contact cleaner, them them dry / air out, put some of the dielectric grease on the connections and then reconnect everything. Seemed simple enough, but didn't want to cause any problems, etc.

Well @dar124, since you're posting in an 8 year old thread and asking a guy (Matt_) who has not been on the forum in over 3 1/2 years a question, I figured I'd go ahead & answer you.

I can't say I'd feel 100% comfortable spraying anything on the PCM. If you inadvertently get any of that stuff on any of the sensitive interior components of the PCM, you're probably going to have a bad day.

I don't see a problem with putting dielectric grease on the connections for the PCM though.

Thanks @Big Blue Yea, I saw this was a really old thread and considered starting a completely new one. But I figured since it was a question about dielectric grease, I'd just post in this thread to keep everything together.


That makes sense about the PCM. I just figured the contact cleaner would be good to clean things up a bit if there was any corrosion etc starting, but definitely don't want to cause problems as I'm trying to do some preventive maintenance!!

Yep, always better to heir on the side of caution, so, you don't cause yourself any unnecessary headaches.
