silicone grease for spark plugs

Postby markren2004 » Thu Oct 25, 2007 12:02 pm

I'm about to service my Megane, including changing the spark plugs, i hear that i should re-apply silicone grease to the coils/plugs contacts.
I've just been to Renault and they want £40 for the grease !!!

anyone know of an alternative "cheaper" brand to using Renault's own.
A link in the reply would be nice, so i can see what i need.
thanks in advance.

Can't see why it would be so expensive? :shock:

This might do?

I assume the £40 was for a VERY large tub of the stuff :-)
I didn't wait long enough to find out.

what i'm wondering is if Mulit-purpose silicone grease can be used

or do i need stuff that complies with a particular standard ?

That's the same stuff as my first link to CPC's website!

Don't see any reason why not?

The "grease" specified by Renault is not silicon based, it is a high insulation non setting insulation compound..

Yes it is indeed £40 for a small tube! A complete tube would be enough to insulate around 100 cars...

found this on a french website and translates to...
FLUOSTAR 2L Grease of electrical waterproof quality without silicone

which led me to...
PFPE synthetic fluid Grease
Viscosity ISO VG 150 (135-165 cSt / 40°C)
Automotive equipments Mechanical engineering

so it does sound very specialist, although this looks like it might do the job...

one of the FAQ's is
Q) Can I use this on ignition coils on a car - TDA
A) Yes the product does support that.

The original grease is made with fluor and not silicone based, as Webcode said.

Good to hear from you, Webcode!
