What do you guys use on aluminum? I get different answers. I use eezox to prevent rust but it stained my aluminum breech. Not sure what to use on it so the bolt runs smoother. Your help would be appreciated. Thanks

for general protection, air venturi metalophilic oil .. moly paste is good on things like your talking about but it may indeed have a staining affect .. i know something that has excellent lubing qualities and would not stain or cause a mess - dupont chainsaver with teflon, excellent stuff ...

Here is a link to an independent test of 46 different products that inhibit corrosion and reduce friction.

Good old 30W non-detergent oil or automatic transmission fluid (ATF) is good for aluminum. Molybdenum (moly) is not a particularly good lubricant for it the way it is for steel.
And not to put too fine a point on it, but bare aluminum oxidizes, it does not rust. The oxide is actually harder than the base material and provides protection so it is a good thing. Same principle with anodizing, only anodizing can be better.
That's why keeping a mirror polish on aluminum rims is an exercise in futility. Mother Nature will beat you every time in that battle of attrition.

Can all these oils be used when using HPA?
-
Please be more specific about where you would use it. There can't be many places where there is a combination of high pressure air and moving aluminum parts that are subject to wear. Actually, I'm struggling to think of one in the airgun world.
A thin film of oil on the breech and bolt, for example, is okay. Coating the inside of a HPA cylinder or bottle is not, at least not with conventional oils which may be subject to combustion.
Silicone oil is commonly used where combustion is a concern. It is good for O-rings sliding on metal, such as a bolt O-ring or dynamic O-rings in a high pressure pump. However it is not a good metal-on-metal lubricant.
