Maintenance, Servicing and is Silicone Oil good or bad?

[Missed_dinner]

Servicing: What is involved in a service by a manufacturer/Air gun repair agent? and how often should it be done?

Maintenance: I have been told to wipe Silicone oil over the metal and wood parts of my guns to keep them free moving and free from corrosion and rust. I was also told in one RFD to not bother doing anything to my pistols. is this correct?

BUT this is printed in my BSA ultra instructions.... (see middle paragraph)

no silicone oil on metal to metal parts . it will seize them.

A old myth

Silicone is NOT for metal to metal BUT

To say it locks up a gun in a few shots is a myth Steve Pope says to use it for fitting piston seals in his instructions.

Also check this video out does this gun look like it's locking up this gun solid ( I dont recomend though )

close the little add so you can read the secret formula

Silicone oil should only be used by those who understand it as it is not for metal to metal

I disagree. A true story and no myth: Many years ago, I bought a brand new HW35 from MAG, together with a bottle of silicone oil, which was recommended for wiping on the stock and action. In my excitement, I didn't listen and I subsequently used the oil on the breech pivot, amongst other places.

I took the gun out and within 20 or so shots, noted tge gun was becoming progressively harder to cock, to the point that the application of any more force would have bent the barrel.

I took the gun back to MAG and they diagnosed the problem immediately, stripping the gun to show me the severely galled shims and breech block. Needless to say, they quite rightly voided the warranty, but they did give me two new shims FOC. I took the gun home and polished the galling out of the breech block, reassembling with moly grease and it was as good as new.

That's why I've never used silicone oil since - even on 'O' rings.

P.S. in the write-up below the video he says that only the elastomeric seal touches the cylinder walls. Thus he is not using his concoction for metal to metal contact, which is where pure silicone oil and/or grease causes problems. There are mamy superior greases, e.g. Krytox, which can be used on elastomers and metal to metal. Why take the chance?

...Why take the chance?

Sums it up nicely.
If the anti-silicon crowd is wrong, you just use another lube and no harm is done - if the pro-silicon crowd is wrong then your gun could be destroyed beyond repair.

Well, I DO use silicone oil and have used it for donkeys' years on the externals and wood.

Obviously, I'm wary of the pitfalls, so use it very carefully and sparingly. I've had some of my guns for 35+ years and they look as good as new.

And, yes, a big "No, no" for metal to metal.


I do appreciate that lubes like Ballistol etc may be just as good for protection and without the potential risks and may certainly try it sometime (who knows, I might even switch then?), but so far, silicone, sensibly used, has served me and my guns well.

I actually agree with most of your post but the myth that I am talking about is that silicone oil will seize a gun solid after just a few shots caused by just a few drops of silicone oil then contaminating the rest of the metal, after you changed the shims in your 35 and polished out the galing regreased it was OK. If a little silicone got mixed in with moly you wouldnt know any difference.
BTW have another look at the video at all that silicone oil and grease being pushed into the cylinder.

Dont forget when Ben Taylor was dripping silicone into his gun all those years ago he didn't understand what it was for, I bet he does now though LOL

I would never use slicone oil - even externally. Too much risk of it getting between metal to metal contact areas and causing galling. Don't ask me how I know. BSA are correct.

Ballistol, used sparingl, is a much better choice for use pretty much all over. I wouldn't use it (or anything else not recommended by the manufacturers) on the internals of a PCP, though.

Personally I would not let anyone else service my guns a) on price and b) because I wouldn't trust anyone else with my pride and joy. Depends what type/make of gun, of course.

Browning Legia is also good for wood and metal! Also nearly twice as much in the tin for the same money
