Abbey gunlube sm50

[Zomboid]

Im confused. There should be no silica in any lube as its a hard mineral aka quartz. Silicone manufacture uses silica as a starting point but it shouldnt be in the finished product any more than sand in your beer glass.

For my other 2 pennorth I have always thought SM50 was moly in silicone oil. Pretty sure it was advertised as such last century.

I'm going to dig out the Abbey lube sheet I got in the late 80s. sure I still have it.
