I've seen your question on the other airgun forums and read Tim's Holier Than Thou pronouncements that you will ruin your air gun if you don't use his Secret Sauce. His oil is good, but so are a lot of others. I have no experience with silicone shock oil mentioned on other forums. I have heard that it is good for shocks because it doesn't thin out when it gets hot and won't attack rubber/Viton parts in an airgun. I have also heard it's not so good for metal to metal contact.
I have used Secret Sauce (rumored to be hydraulic oil), Pelgun Oil, synthetic motorcycle fork oil, electric motor oil by 3 in 1 in the blue can, air tool oil, Marvel Mystry Oil and 30 wt motor oil. I have also taken Crosman 1377 pistol apart that have used those oils and found all of them to be in excellent contition. I am currently using 30 wt motor oil in my 1377 and red Pelgun Oil in my IZH-46.
What it boils down to is airguns are not as delicate when it comes to oils used in their lubrication as most think. I'm not talking about spring piston guns. Those are an entirely different matter.
