In a rare moment of weakness, I read the manual on the Benjamin 392/397 seeking instructions on oiling the pump cup...
There ARE none!!
The manual instructs the owner to put a drop of oil on thr pivots and riveds about every 250 shots or so, but makes no mention of the pump cup!
Or, am I missing something??

IIRC, the Mac1 Lore of Old says to only oil the pivots and the oil will migrate to the cup without an excessive amount getting into the valve.

From the Mac1 website:
Lubrication:
EVERY TIME YOU TAKE IT OUT TO USE IT YOU WANT TO MAKE SURE THAT THE LEVER PIVOTS ARE MOIST WITH SECRET SAUCE. You'll get a 1.75oz bottle of Secret Sauce with every Steroid purchased or upgraded.
Don't overdo it, a few drops at the front pivot & rivet is all you need on those two. The pivot that connects the lever link to the piston end that guides it is a porous piece of steel. Put 6-8 drops of Secret Sauce on that pivot as the guide end of the piston acts as a storage of oil so a film is laid down on the tube each pump stroke. All else will get taken care of by blow through.
Never put lubricant in the air hole. Do NOT use firearm cleaning solvents or lubricants anywhere on the gun. Rem Oil & Barricade provide a good external wipe down oil. I use Rem Oil as it has proven to be one of the best rust inhibitors. Don't put your guns away with salty paw prints all over it. When you take it back out the steel parts will be all rusty.
