Sorry for all the questions--------------but new to airguns. What do you guys use to oil the breech seal and after how many pellets should this be done?
I am currently using Pellgunoil. Is there a generic type oil that can be used such as vegetable oil, cooking oil, etc? Thanks again for the info.

You probably don't really need to do much at all to your breech seal. Try not to get any flammable oil into your chamber, the high compression can cause it to vaporize and diesel (that's a small explosion).
A little pellgunoil used so far won't hurt much, but wipe as much off as you can.
When shooters oil their springers, it is usually to keep leather piston seals from drying out. This is done very sparingly, after 1000's of shots.

I've never oiled my B3's breech seal since I don't want to introduce anything into the breech and barrel that doesn't really need to be there. Ed

Just save your pellgun oil to your CO2 shooter or perhaps you're talking about the piston seal? Tuned springers don't need to be lubed for it's got all it needs during the process. Untuned ones, they have silicone chamber oil that brings back life provided the seal is not bad. One drop in the port hole and let sit overnight and cycle it for leather seals they recommend 2-3 drops every 500 shots. For the synthetic seals aprrox. 2000 shots, don't overdo for it means trouble.

If your B-3 has a leather piston seal (and they do, don't they?), then you need to be using pure silicone oil. Try a hobby shop that sells R/C cars - they use it in the shocks from what others have said. I found a small spray can at a hardware store. Enough for about a hundred years. Just be sure it is pure w/o petroleum products. Pelgun oil is just about 30W non-detergent motor oil. You can also make a mix of two parts silicone oil to one part neatsfoot oil. Add a couple drops through the transfer port (where the air comes out) and stand on the butt for a couple of days to let it soak in. Once in a good while should be enough to keep it supple.

Thanks for all the info. It seems as though the Chinese springers with leather seals require lube. I have a Gamo Big Cat where the owners manual says "no oil for the breech seal".
I also have a Ruger Air Hawk (chinese) that requires oil. I just don't want to over do it with maintenance.

Air Hawk has a synthetic seal, not leather. I would not oil it, myself.

Ray, don't be sorry for the questions, we were all new to the sport at one point. I have been into it less than a year myself. You will find that your GTA brothers will gladly give you good and SAFE advice on any question you have. The only dumb question is the one not asked. Your friend, snookman

WOW Redfeather---------I am surprised. The owners manual says to lubricate this is from their manual:
Two(2) drops of RWS Air Chamber Lube every 1000 shots
will suffice. It is easily applied through----------------------------

Thanks Snookman----------------appreciate it

My take is that two drops in a thousand rounds probably isn't going to do much damage, if any. But that's chamber oil, not spring oil, 3-N-One oil, WD40, etc. Chamber oil ought to be non-combustible like silicone oil. One problem might be putting in too much and then shooting immediately afterwards, thereby creating a slight hydraulic lock which can damage the seal. Or it could make the oil very hot. You know, it seems like even the internet blog gurus still advise this treatment. FWIW, if and when you ever tune your Air Hawk, just apply some good JM moly paste to the piston and you won't have to worry about it.
