Thanks for your replies. I have to learn where to apply this pelgun oil, and/or silicone oil.
If a co2 or hpa rifle lost pressure over a short time in storage then that would suggest that some seals are shot?
Put a drop of the right oil on the tip of a cart when you load it. For a ssp or multipump there is usually a sponge of visible piston when you open the pump arm, lube that spot. Don't over lube it will just mess up your barrel. Put silicone oil on your fill probe or tip of your Foster for filling PCP/HPA.
Sometimes the seals just get dry and may have a set or flat spot. A shot of pelgun oil or a strip and relube may restore the function. It's pretty common for guns to have "slow leak", so if you put it away and come back in 2 months and find the air or CO2 has leaked out it an indication that there is a minor sealing issue, likely if you shot the gun more frequently it wouldn't leak down to zero that quick. What Daryl does (dry fire occasionally) is actually a good thing, because it allows the valve to open and get a bit of lube on the seals to help preserve them. Incidentally, for CO2 guns straight weight SAE30W oil (no detergent) or ATF can be used as a substitute for Pelgun oil which cost about $1000 for a l. Silicone oil is cheap and there are many sources, such as CT look for treadmill tread lubricant.
