Question related to CO2 Pistol maintenance

[Bremijo]

I have a PT-92 made by KJW, and I have recently bought a new magazine for it to replace one with a leaky valve. The reason I'm pointing this out, is that I'm going to be going to university in a few weeks, and I'll be away from my guns for a while. I would rather not have a situation where I buy something new, have to leave it for a while, come back, and find that it's broken for some reason related to not maintaining it.

I understand that for pistols it's important to put silicone oil on it once in a while, and my question is:

If I leave my pistol and magazine unattended and unused for a period of a few months (with occasional visits home), will anything bad happen? Will anything wear out? Keep in mind they are well oiled and I plan on applying more before I leave.

I have some friends I can trust to take care of my stuff, but I can't guarantee they'll remember to do maintenance.

I'm hoping that this is just a stupid fear to have, but I'd rather not come home and find that my pistol (which I hadn't been able to use for a while anyways...) is broken, yet again.

Any help would be appreciated.

On a side note, I also have an Echo 1 M14 AEG.... is there anything I should know about leaving AEGs for prolonged periods of time?:-?

EDIT: turns out the only lubricant I have left now is this stuff called 'Losi Shock Fluid, 20wt' it says Certified silicone on the front but does anyone know if it's got any petroleum in it? I don't want it to affect my magazine internals.

Leaving it alone is ok. Try to oil it a bit on every metal part and get some silica salts in there to help keep the moisture out.

Thing to be careful about the aeg is to make sure the piston has fully cycled so that it doesnt stay in a compressed state and lower the tension of your spring overtime.

You should still charge the batteries a couple of times during that period so that it does not start to degrade.

All that comes to mind right now.
