I believe what you want is siliCONE (IIRC it's the one that's "synthetic" right?) the other one (silicon) is used as a conductor, ie. like in computers )semi-conductors), after all that's why they call it Silicon Valley right. Silicone is used in industry as a lubricant.
PS: Use the FinishLine teflon grease and be done with it. Another user on Arnies highly recommends it over White Lithium.

After discussing in another thread how low my opinion is of Lithium grease, I now have concrete evidence of how rubbish it is.
First off, the Lithium in the grease, offers no lubrication properties, its simply used as a thickener.
Well, my Classic Army G36 was acting up the other day, running very poorly, sounded strange, strained. I had not used it in nearly a year. I tried to chrono the gun but the shots were sounding so bad, I put it away and took it apart a few days later (today)
Well, first thing I found was that the grease had become very tacky and sticky. It looked like month old mayonase was dried on every part of the gun. It was a struggle to pull the piston out of the cylinder (by hand). Not thanks to a great air seal either. It was crumbly, tacky and where it was on the gears, the gears could barely move. It was like glue in the gun.
I cleaned all the internals and gears etc. Gave the shimming a check. Fitted a nice new bearing spring guide. Put a couple of drops of silicone oil on the O ring and a couple of drops in the cylinder. Used my finger and moved it around. No sign of damage or wear to any of the parts, which is to be expected as this gun has had very little use.
Re greased with ceramic Teflon grease (I perhaps used a bit too much) and put the gun back together again.
Pulled the trigger and the motor could barely turn the box over, it ran better than before but it sounded terrible. I tried a different motor and POW! The mechbox jumped back to life and after adjusting the motor hight, the box is sounding great. I used a 5SKU torque motor (only spare one I had). The Classic Army motor is stuffed. Its got no power any more. I am convinced after what I saw in the mechbox that the horrible Lithium ###### killed my motor. It was so sticky and tacky, I think it would have strained any motor and drained batteries very quickly. For the record I was testing with a 7.4v 2200mah 25c Lipo at full charge and a fully charged 1500mah 9.6v stick type NiMH.
Those stock CA motors are a bit slow and a bit noisy but they have more torque than a TM EG1000 though they are slower. There is no way this motor would have struggled in a 350fps set up with a motor like this. Unless the motor was a bad one or something else was wrong. I have as they say, seen with my own eyes what Lithium does to mechboxes.
Avoid this rubbish!
My concern now is I have a Classic Army SCAR H and if it has this same rubbish Lithium grease in it, will it suffer the same fate? Am I going to have to open up that mechbox and sort that as well? Not at all impressed. I guess, I am going to have to open the SCAR H and do some preventative work. Otherwise its going to nag at me.
So, please can we stop telling people to use Lithium grease in guns?
