Use 'real oil'....

Silicon isn't really a lube (it's sand, right?), but it doesn't burn or 'thin down' so it has some uses.

If you have a CO2 gun, you want to use 'real' (hydrocarbon or 'mineral') oil. Crosman Pel Gun oil, for instance. Not 'gun oil' (solvents and additives are tough on seals and if it's on the gun, it will get on your fingers, onto the pellets and into the gun....). Or 'the poor man's substitute, ND SAE 30 weight 'motor oil'. Be sure it's ND (non detergent), harder to find, but it's around. It's used in compressors and the like, often in the Garden section of large hardware stores.

Silicon 'lubes' are only going to gum up the works.....literally. It makes a mess with the oil already there as you found. Hydrocarbons and Si don't mix. One or the other, not both.
