When replacing o-rings, what do I use to lube it?  White Lithium Grease ok?

With all these different lights, my O-Ring collection is growing.  BRD can spread to accessories too!

I use silicon grease that I got at a scuba diving shop.  They sell it for lubing the o-rings in dive gear.

Do not use petroleum base lubricants!!! It will make your rubber crack

So silicone based grease is GTG, pertrollium based is NG.  So anyone use Lithium grease?

Edit - Found out that Lithium grease IS petrollium based.  Thanks for the advise.

Silicone di-electric grease.  It won't cause the O-ring to break down the way petroleum lubricants do.
