Yes, just as well not over the Marianas Trench!My father could not dive deeper than 12 meters and I never hunted with that gun. 95% of hunted fish was mullet in 4 meters of water. And usually when they hunt Tuna the depth is 300-3000! he got lucky to get that gun back!
You need the lubricant to move around inside the gun; "oleo-pneumatic" is what pneumatic guns have been from the very beginning, but common usage discards the oleo and we just say pneumatic. The rubber tube boundary hydropneumatic guns are the only ones that don't use oil. Read the patents to find out.My homemade pump has an almost zero dead spaceAnd I also have a great success with the silicone grease. Will never ever touch a fork oil! It is a poor lubricant since it does not stay in one place. By the way an o-ring on Cyrano piston (11 mm) is a standard 011 USA size - cheap and common!
Look, I am trying to help you. You never used the silicone lubricant and I have - on three guns. It performed way better than the stuff you bought. I had severe issues with the fork oil. I use a silicon spray that turns into powder when it dries on the inner barrel and I use silicone grease an all o-rings. I also use the same approach on my pump that i MADE and DESIGNED myself instead of the Cyrano-supplied garbage that costs 7 Euros to the wholesaler. You like to argue instead of learning. You told me the last time that the silicone grease destroys o-rings when modern viton and buna o-rings are even impervious to the motor oil, let alone the silicone grease that is safe to eat. It is used to lubricate machinery in the food industry. Liquid lubrication is used when it can circulate and thus reach all places it needs to go, solid lubrication is more expensive and needs to be re-applied but in between re-applications it is superior to a low-viscosity liquid. Anyway, I am extremely glad that I got rid of that fork oil garbage that does not lubricate properly.You need the lubricant to move around inside the gun; "oleo-pneumatic" is what pneumatic guns have been from the very beginning, but common usage discards the oleo and we just say pneumatic.

Never heard of such a proverb - you made the shit up. "silicone grease crystallizes" - get medical help, dude. Seriously. It NEVER DOES. Anyway, I am out, can not spend time on stubborn foolsThere is a good Russian proverb: To teach a fool - Heal the Dead! Silicone grease does not spoil the O-rings without movement and is suitable for fixed seals! When silicone grease crystallizes, the O-rings involved in the movement fail due to the lack of a lubricating effect! ATP liquid lubricant gives a guarantee of sliding of the O-rings of the pistons and the correct operation of the valves! Learning is never too late!
If something is not broke why fix it? My "Sten" has used fork oil ever since it was first serviced, I only stopped using that gun when the power regulator piston cup seal tore as the early (1967 - 69) guns did not use an "O" ring at that position. As I did not always use the regulator for loading I still used it on occasions, but mainly use my Scubapro "Magnum" as it has similar handling and a similar sculpted grip handle. There are also different fork oils, I use Castrol which has been around for longer than I can remember and is a quality product.Here is a long thread on Italian forum about pneumatic lubrication: https://pescasubapnea.forumfree.it/?t=75050110
I would say they prefer silicon oil...? I had been using fork oil for years without problem. Then once, when I sold may Cyrano 1100 the guy who bought it asked me about the oil in the speargun because the O-ring were in very bad condition, like decomposing. I told him that it was fork oil... He haven't used the speargun for months after he received it.. I still do not know what was the problem...
