Silicon Oil; substitutes?

[XxBatteryxX]

Is there any substitutes to using silicon oil in a Co2 pistol (since co2 obviously doesn't already contain it)? Or if not are there any non-airsoft specific stores to buy it at? (Wal-mart, Canadian Tire?) Help would be super, greatly appreciated!

100 percent silicone oil only, and find a local hobby shop and ask for 100 percent shock oil for RC toys

You can get silicone oil at any R/C or hobby shop (ask for 100% silicone shock oil, pick a very light weight one).

For CO2 you can also use (and I actually recommend) Crosman Pelgun Oil, which you can get wherever they sell pellet guns I guess. It's better formulated to handle Co2 than just silicone oil, which is used with propane) and will help protect your seals and avoid leaks from developing.

And where do I apply it on my gun? This will be my first GBB airsoft gun.

Usually (with propane) you'd put silicone oil in the filling adapter so it shoots into the mag along with the gas; it'll work its way through the gun's valves and stuff from there.

In the case of Co2 (and with Pelgun Oil) add a drop to the top of the 12gr Co2 cartridge before inserting it (put the drop where the piercing probe will stick into the cartridge). Most of it will go on that o-ring (which is what you want) and some of it will pass through the gun. Some brands of 12g cartridges also contain a small amount of lubricant in them (but you'd still want to use the pelgun oil).

Thank you very much! That is such a big help! Should I be putting any oil/lube on/in the barrel because of the slide causing so much friction?

Anywhere there's friction
Slide's tracks
Around the nozzle in the BBU (blowback unit -> under the slide, when you remove it, under the rear sight. You'll see a polymer cylinder that can move back and forth. Best is to disassemble it when you are comfortable enough)

Ideally, clean with Q-Tip and small dab of oil before reapplying new oil, after every shooting session. Clean barrel with cotton patch; Someone else might chime in about using oil or not in barrel, I'm not too sure about this.

You can oil the o-ring inside the blockback unit in the slide but I don't recommend oiling the slide or other friction/contact areas; oil is just too light and will only end up being a dirt magnet. For those areas you should get some silicone grease, white lithium grease or Ultra Slick synthetic grease (all available at Canadian Tire in the automotive section).

While we are on the subject, should I add a little bit of this pellgun oil to the inner barrel of my AEG when I'm cleaning it after useage? I watched a video a while back I recall and the narrator said to do just that.

[Styrak]

No, never use petroleum oils on your airsoft guns.

You can use silicone oil to clean the inner barrel if its really dirty, but you don't have to. Avoid getting it on the hopup rubber. I wouldn't use Pellgun oil for that (which isn't a synthetic oil). I usually use rubbing alcohol to clean out dirt etc. part of the reason being the fouling you'll get in the inner barrel will partly be atomized oil/silicone from the gas which then attracts dirt. The alcohol helps clean that up (versus throwing more oil onto it). You can clean the inner barrel with a bit of lightweight silicone oil after the alcohol with a stock inner barrel, but a lot of upgraded inner barrels are either polished or coated so you don't need to (and it may adversely affect performance by prematurely attracting dirt).
