Hello, the manual says I can use a non detergent 10-,20-, or 30- w motor oil to lube this gun up, there's also pellgunoil which I might just use. But it says to lightly oil the sponge-like pad (visible when the pump bar is fully extended) I have heard not to do this because it will cause the pad to stick to the walls and rip off. To you 880 owners, do you oil that pad as well as the other lever hinges? Also if you do how often, how much (I'm guessing just one drop) , and which lube do you prefer? Thank you. Sorry for all the questions, I am new to air guns.
