An inside secret!
Here’s a tip all savvy airgunners need to know. There is an oil that CAN FIX airguns! It’s called Crosman Pellgunoil, and here’s how it works. CO2 guns use O-rings and synthetic seals to keep the gas inside the gun. These seals and O-rings need lubrication to do their job. They don’t need it for friction reduction; they actually need it to complete the gas-tight seal between the synthetic seal material and the metal walls of the gas passages.

At microscopic levels, the metal walls of the gas passages in an airgun are very rough. So are the surfaces of O-rings and synthetic seals. If the seals and walls are left dry, pressurized gas eventually forces its way out through these tiny passageways.

The right lubricant creates a gas-tight barrier!
A thin film of the right lubricant gets into the tiny imperfections in the metal walls and synthetic seals, creating a gas-tight barrier. The pressure of the gas forces the lubricant into the tiny passageways and, if the viscosity of the lube is correct, it doesn’t get forced any farther.

One way to instantly turn a CO2 gun into a leaker is to put some penetrating oil on the seals. The low viscosity of the penetrating oil allows it to flow through the tiny passages. The gas follows after it and right on out the gun.

The end of leaking CO2 guns
Take a gun that’s leaking gas and put a drop of Pellgunoil on the tip of a new powerlet before putting it in the gun. The pressure of the gas carries the lube with it as it flows through the gun (remember, this is a leaker we’re doing this to), until every seal is coated with a thin film of oil.

You can’t see what’s happening, but you sure can hear it. At first, you hear gas leaking from the gun, then the sound will either diminish and go away gradually. More often, you’ll hear a hollow sound as the gun seals itself instantly. After you’ve done a few guns, you’ll feel like a magician as you almost instantaneously stop gas guns from leaking!

How to pay bottom dollar for used CO2 guns
A trick that experienced airgun collectors use to pay less for CO2 guns is to look for leakers at gun shows and garage sales. They carry several CO2 powerlets with them. When the owner says he doesn’t know if the gun holds gas, they can slip a powerlet into the gun then and there! When the inevitable leak turns up, the price reduction for a leaking gun can be very dramatic!

Sometimes, oil will not fix a leaker. In those instances, resealing the gun is the answer. But, you’ll still get a price reduction when you try this trick. Use Pellgunoil when you’ve gotten the gun home to see if that’s all it takes to seal it up tight again.

I’d like to hear from those who either have done this in the past or who try it for the first time.

  5. I just put a drop of oil on the tip of the powerlet that’s about to be pierced. The piercing needle is fine, too.

    You can do it with every powerlet, if you like. It’s impossible to over-oil a CO2 gun this way.

    As far as the rails go, I would do whatever the manual recommends. They are not as important as the powerlet, because that’s what keeps your gun sealed.

    B.B.

  6. THANK YOU FOR YOUR ADVISE ON PUTTING PELLGUNOIL ON THE TIP OF THE POWERLET. YOU SAID I CAN DO THIS EVERY TIME I INSERT A NEW POWERLET RIGHT? I INSERT A NEW POWERLET EVERY 60 SHOTS, SO IS THAT TO OFTEN? OR CAN I PUT A DROP ON THE POWERLET EVERY TIME. ALSO CAN I PUT ONE DROP ON THE NEEDLE ITSELF ALSO? THANKS. CHARLIE

  8. I OWN THE WALTHER PPK/S CO2 AIR PISTOL, I HAVE 2 QUESTIONS FOR YOU. I DONT WANT TO EXPERIMENT ON MY GUN IN FEAR OF DOING DAMAGE TO THE GUN THANK YOU. CHARLIE

    1. WHAT HAPPENS IF YOU KEEP RECYCLING THE SLIDE WITH A FULL MAGAZINE OF BB’S WITHOUT FIRING THE GUN? IN A FIREARM THE BULLETS ARE EJECTED? ARE THE BB’S ALSO EJECTED? I DON’T WANT TO EXPERIMENT IN FEAR OF DOING DAMAGE TO THE GUN.

    2. CAN YOU DRY FIRE THE GUN WITHOUT A CO2 CARTRIDGE IN PLACE? OR IS THAT BAD FOR THE GUN? THANKS, CHARLIE

  9. Charlie,

    If you cycle the slide by hand with a full BB magazine loaded, nothing will happen. The BBs are not fed into the barrel in the same way that firearm rounds are. When the CO2 pistol fires, a blast of compressed gas blows the top BB out of its seat in the magazine and down the barrel.

    You can dry-fire the gun safely by removing the magazine and simply pulling the trigger (if there is CO2 in the gun, of course). No harm will be done to the gun this way. The cycling of the slide is totally independant of a BB being fired, though there will be a blast of gas that goes down the barrel because the firing valve will continue to operate in this mode.

    I have shot my own PPK/S HUNDREDS of times like this to safely demonstrate the blowback action.

    B.B.

  10. B.B. THANKS FOR YOUR QUICK RESPONSE. IN THE DRY FIRE QUESTION, I KNOW WHAT HAPPENS WITH A CO2 CARTRIDGE IS IN THE GUN, AND NO MAGAZINE, BUT WHAT HAPPENS IF THERE IS NO CO2 IN THE GUN? WILL DRY FIRING THE GUN DAMAGE ANYTHING? DOES THE HAMMER STRIKE ANYTHING THAT IS FRAGILE? CHARLIE

  11. Charlie,

    I have a private rule to not fire any gun that does not support dry firing. Firing the PPK/S with CO2 in it is not really dry firing, but without it, there is nothing to cushion the hammer fall.

    While I can’t see anything that could be damaged, I’m not going to recommend it.

    B.B.

  13. WHAT IS A SAFE WAY TO DISPOSE OF EMPTY CO2 CARTRIDGES? I DONT FEEL RIGHT JUST THROWING THEM IN THE TRASH CAN. ANY SUGGESTIONS WOULD BE APPRECIATED THANKS. CHARLIE

  16. WHAT IS THE LONGEST TIME YOU COULD KEEP A CO2 CARTRIDGE IN THE PPK/S WITHOUT STRAINING THE SEALS?
    ALSO IS THERE ANYTHING BAD ABOUT KEEPING THE EXTRA MAGAZINES LOADED WITH BB’S WILL IT STRAIN THE SPRINGS? CHARLIE

  17. Charlie,

    I don’t think the seals will be hurt by being kept under pressure. I just fired a shot from one of my PPK/S pistols that has had the same powerlet in for the past year. It fired perfectly.

    Do I recommend that you store your gun with a powerlet in it? I guess not, though I can’t think of why not, other than the manufactirer doesn’t recommend it. In fact, if you read the manual, they don’t address the question at all.

    As far as straining the springs of magazines, I’m anal on that question. Ever since I ruined a lemonwood longbow (a leaf spring, not a coiled spring) by not unstringing it between uses I have always kept tension off springs whenever possible. I even favor revolvers for self defense because I don’t trust magazine springs for the long term. That’s pretty ridiculous, but that’s how I am.

    B.B.

  19. I HAVE PELLGUN OIL FOR USE ON MY PPK/S I DIDNT KNOW THAT YOU SHOULDNT USE ORDINARY GUN OIL ON AIR PISTOLS AT FIRST NOW I KNOW. BUT WHAT ABOUT WD 40? IS THAT AN OIL? CAN THAT BE USED ON THE METAL SURFACES OF THE AIR PISTOL? PLEASE ADVISE THANKS. CHARLIE

  20. HI ALL, I WANTED TO KNOW HOW MANY BB’S MY PPK/S AIR-PISTOL WOULD FIRE ON 1 POWERLET CO2 CARTRIDGE. AFTER 6 MAGAZINES (90 BB’S) IT WAS STILL WORKING GOOD. WHEN I PUT IN THE 7TH MAGAZINE, AFTER 3 SHOTS THE SLIDE DIDNT BLOW-BACK I HAD TO COCK THE HAMMER BY HAND. AND I NOTICED THE POWER WAS WEAK. HOW MANY SHOTS DO YOU GET? WHAT IS CONSIDERED GOOD? WAS THE REASON IT DIDNT BLOW-BACK BECAUSE IT DIDNT HAVE THE POWER AFTER 6 MAGAZINES? THANKS FOR YOUR TIME. CHARLIE

  21. Charlie,

    Usually you can expect to get 50 to 60 shots from a CO2 pistol. Now, the PPK/S isn’t real powerful, but some of the gas has to cycle the slide, too, so I’d say you are getting a higher number than would be expected. It’s warm now, and that helps.

    If you remove the magazine and just shoot to cycle the slide for fun, you can get several hundred shots, unless you do a lot in rapid succession. Then the gun cools too much and uses too much CO2.

  22. HI!!

    I’m a relativly new airgun enthusiast and right now am using a crosman 781 as my introduction to air rifles.

    I was recently experiencing reduced performance and was wondering where I am supposed to apply the pellgunoil. Do I apply it around the o- ring only, or do i allow it to seep down the air chamber?

    thanks!

  23. When you open the pump lever all the way there should be an O-ring or felt washer that barely becomes visible at the end of the pump rod (looking through the slot in the bottom of the gun. That’s where the oil goes. It seals the air so it can be forced into the gun as you pump.

    B.B.

  25. Hi, I just bought a Crosman 1077. The last air rifle I owned was a Crosman 760 (what else?) about 20 years ago when I was a teen. They didn’t have Pellgunoil where I bought ammo so I bought Remington Rem Oil (with Teflon) instead. Is this safe to use instead of Pelgunoil? Thanks.

  27. Hey,

    right now I have a 781 crosman and had some issues with the seals. Fixed it with the advice found here, thanks.

    My question is off topic, how do i shoot bb’s from the 781? do i just pour it in the spout and shoot as normal? Do I pump for it, everyshot same as a pellet?

    Thanks

  28. Crosman 781,

    To answer your question I looked at the Crosman 781 AK manual posted on the Pyramyd AIR website.

    Pur the BBs in thorugh the loading port on the left sifde of the receiver behind the trigger. Close the port cover.

    Hold the gun muzzle-down by the pistol grip with your thumd pulling back on the BB retainer button located on top of the receiver. Now twist the gun frome side to side, while you hold the BB retainer button back.

    The visual BB magazine (a slot on top of the receiver) fills when you do this. Now push the BB retainer button forward to hold the BBs in the magazine.

    With the muzzle pointed down, open the bolt all the way back to cock the gun. A magnet on the bolt will pick up a BB. Make sure the pellet magazine has no pellets in it and close the bolt. The gun is now ready to fire.

    I would go look at the manual, because the pictures will help you understand what I have wreitten.

  29. I just wanted to know why my walther ppk wont fire i have inserted the co2 and tightend it and still no results the trigger does not pull back all the way. also if you remove the co2 can you still use it after you have already removed it.

  32. thanks for all the information bb, i just purchased a crosman cp99, a great gun, and i am going to go buy a couple tubes of pellgunoil and put it on my powerlets when i shoot, and on the piercing needle thing. the questions everybody has asked along with your answers have helped me alot. thanks again

    mike

  33. I have a walther ppk/s co2 airgun, and i was shooting it like regular. For no reason the slide came off. The spring is still there,but I can not figure how to put the slide back on. What should I do. Does anyone have a diagram. I don’t know if I am missing any pieces,or not. Please help.

  36. You can use non-detergent motor oil in Daisy guns, on the O-rings. Daisy recommends 20-weight oil.

    They used to have a silicone oil like Pellgunoil, but when they stopped selling it they had to come up with something else. They won’t recommend the oil from a competing brand.

    If you can find pure food-grade silicone oil, that will work in place of Pellgunoil, too. However, it probably costs more.

    Automatic Transmission Fluid also works as a Pellgunoil substitute.

    B.B.

  37. Hi,

    Where exactly on the gun should I oil the slide on my PPK/S airgun? The manual just says to do it with no further explanation. (My Crosman .357 airgun manual states specific oil locations.)

    Thanks.

  41. i applied one drop of gamo gun oil into the compression chamber of my crosman quest (i dont think all of it went in… some of that single drop remained on the outside near the seal). i thought it would work the same as crosman pellgunoil. i havent noticed any damage to my gun yet. do you think i damaged my rifle? and if so what would i need to do to fix it?

  44. I had a very bad experience with Crosman Pellgunoil.

    I bought a Daisy 44, and it was alright for a week or two, then it began to leak very slowly. I heard how good this oil was supposed to be, so I ordered some. When it came in, I applied a small amount on a new Co2 cylinder. When I turned the screw, the slow leak turned into a HUGE hissing leak. I then tried another. Same thing. I was frustrated, to say the least. I waited a day or so, after the oil dried out. I then tried another cylinder just for the heck of it, and IT DIDN’T LEAK! But soon it was leaking slowly again, so I tried more oil. This time the gun was completely ruined, would never hold gas again so I took it apart and could never put it back together again, unfortunately.

    I then had a fine working Daisy 15XT. I decided that the Daisy 44 must have been old and couldn’t handle the Pellgunoil. So I began using some on the new Daisy 15XT. One day, it started to leak really bad, all Co2 would be discharged within 10 seconds. So I tried more oil. Worse than ever. I gave up on it and thought it was broken. A few days later, I gently wiped any remaining oil, and for the fun of it, tried a new Co2 cylinder – and to my surprise it didn’t leak amnymore (although there is a slight tapping noise, but the hiss is gone.)

    So in conclusion, I think Crosman Pellgunoil was to blame.

  45. Hi I am also a new air gunner with my new 781 crosman, its great but I havent seen any stores around with any Pellgun oil. When I try to buy from the Online site, it says it only ships to the States (Im in Canada)…Also, because I am in Canada it is winter and is very cold, my gun also frosts up when im out for a while. ANy recommendations? Negative effects? Should I only shoot in summer? 🙁

    Thanks alot

  47. Wow thank you for replying so quickly. The Manual recommends re oiling every 250 shots? Is this necessary? I have already put out well over 100 im sure. Im having so much fun with this thing.

    THanks again

    Kevin

  49. A couple stores in the next city apparently has some oil there, I guess ive found some (hopefully)

    Most importantly, after letting my airgun sit on its side (I am assuming this is a no no?), I realised a HUGE amount of clear oil had leaked out of it Eeek! Was it overoiled in factory, was it just because the way i had it or is there possibly something wrong . ?? (the gun itself seems to pump and fire fine)

    Thanks again 😀

  51. Crosman Pellgun oil isn’t good in my opinion, especially on CO2 guns. Makes them leak for me. Daisy even says no oil is necessary in their manuals. They must make seals out of better/tighter rubber now or something and the oil loosens it up.

  52. Daisy certainly is not going to recommend anything with the Crosman name on it. They don’t even mention that name in their building.

    Daisy used to sell an oil of their own, but after the company stopped making their own guns they sort of forgot how the things work and they came up with the 20-weight non-detergent motor oil suggestion.

    Every Crosman repair station uses Pellgunoil to seal a job after it has been completed, and even big bore makers like Dennis Quackenbush not only recommend it, they sell it, too!

    B.B.

  53. So what happens to the gun when Petro based oils are used ?………It is more of a gradual, continous effect isnt it? Seeing it shouldnt bee too much of a problem shooting with a small lack of oil, Im going to keep firing because I will be in the City on the 14th.

  54. Well here’s a question. Why would a Daisy CO2 pistol leak after using a small amount of Pellgun oil on the puncture pin? It didn’t even leak before. But when I stopped using the oil it was fine, like it was before using oil?

  55. I don’t know why the Daisy pistol leaked when you used Pellgunoil, but it wasn’t the oil. Are you referring to the brief time the pistol takes to seal when the new powerlet is pierced? That can take 3-5 seconds for a dry gun.

    I do know that if you don’t use the oil, your gun will eventually leak.

    B.B.

  56. If it wasn’t the oil, then why did it leak immediately after using it but never before that?

    It’s been going on 6 months of not using the oil, and it’s not leaking since I stopped.

  58. I received an old Crosman 760 over Xmas and it shot great the week that I first got it. I then oiled the pump, stored it for a month, took it out recently, and only got two BBs to shoot before the pump started leaking fast – the air just fizzes out the barrel. Tried adding more Pellgunoil, pumped it a bunch, but no seal or pressure, and BBs don’t shoot. Should I send it to the shop for repair?

  59. What probably happened is a piece of the valve seal broke off or cracked. When they get old, they tend to harden, especially if they haven’t been oiled in a long time.

    The valve in a 760 is a blow-off type instead of a more typical knock-open type. It needs to be pliable to work. The gun would probably have leaked no matter what was done to it.

    Yes, the seals have to be replaced.

    B.B.

  60. My ppk/s co2 pistol is not firing any more. It is very new. The hammer does not appear to be striking the pin at all, and right before it completely stopped working, the slide wouldn’t go in to the fully frontward position. It stopped about half of an inch too short. (if this is a clue) Please help; very frustrated! thanks!

  62. Gas guns use a CO2 silicon oil mix called green gas as a propellant. Most Gas guns are semi automatic while some are semi and fully automatic. Gas is discharged to propel the BB forward and the slide to the rear while mimicking the action of a real gun.

  64. I hope you are referring to Pellgunoil and not that comment about green gas.

    Many people feel silicone ATF works well as a substutute. I never heard of using brake fluid, and since I once ruined a Ford Aerostar brake system by using the wrong type of brake fluid, I cannot recommend it.

    B.B.

  67. I concur with the oil recommendation. I have the Walther Nighthawk and cannot begin to comment on how using “Pellgunoil” provides not only an air-tight seal,but actually improves performance of the pistol from the mechanics to shot throughput. John B.

  68. Hey i have a walther ppk/s c02 pistol and when i put RWS capsules in my gun they work fine but my friend gave me some of his c02 capsules and these ones leaked could this be my gun or faulty c02 capsules??

  69. Did you rwad this post? Pellgunoil should stop all leaks like this. In your case they are caused either by small manufacturing tolerance differences in length por by a rough surface of the sealing face of the cartridge (the flat spot) and a thin seal in the gun.

    B.B./

  70. My son left a Daisy Powerline 15xt C02 gun with me when he shipped out with the Navy. I installed one powerlet and used it for about a week. When it was empty, I installed another which immediately leaked out inside the handle. Thinking it was a faulty powerlet, I installed another. This one spewed gas out the top of the gun.

    Can this kind of leak be repaired, or do I owe my son a new gun before his ship returns?

  72. Being that o-rings and gaskets are simple to replace, where is it possible to get a large assortment of the most commonly used seals? I would assume that some at least are made for applications other than airguns…

    It would be nice to pay a penny or so for each seal rather than several dollars each as charged by repair shops and the airgun manufacturers, at least here in Europe!

  73. Hello,

    I recently ordered a Crosman AS2250XT Air Rifle. My first introduction to the world of Air Rifles. fwiw

    Yesterday was my first opportunity to shoot the rifle. I was going to attempt to “sight-in” the scope.

    I installed the AirSource 88gram CO2 cylinder (the first one)…and I followed all the directions exactly…including a “drop of Pellgunoil” on the tip of the AirSource CO2 cylinder…AND a drop on the “o-ring” on the bolt.

    There was an immediate hissing sound of CO2 leaking from the rifle.

    I went outside to fire the rifle…hoping that the leak would stop as I fired a few rounds…IT DIDN’T !

    Eventually, ALL the gas was leaked out.

    Today, I tried again…I repeated the procedure with a SECOND AirSource cylinder AND the Pellgunoil as described above…the result was the same !

    There was an immediate hissing sound of CO2 leaking from the rifle…AGAIN !!!

    I went outside to fire the rifle…AGAIN…hoping that the leak would stop as I fired a few rounds…AGAIN…IT DIDN’T !!!

    The cylinder was empty within 10 minutes (maybe)…and only 4 or 5 shots fired.

    So now…I’ve wasted two Airsource CO2 cylinders…and apparently have a defective rifle.

    Any suggestions ?

    Should I send the gun back from whence it came ? tia

    skyfisherman

  74. skyfisherman,

    I hate it when this happens. Airguns today are pretty good right out of the box, but yours isn’t. You did all the right things, as far as I can tell.

    Your gun is probably missing a single seal, or the seal is damaged in some way. You can do nothing but return it. But if you have the patience, ask for another of the same gun and see what happens. I assure you this isn’t common. And I think that dealer should replace the two AirSource tanks, as well.

    It’s a shame it had to happen on the first try.

    B.B.

  75. B.B.

    Thank you for the fast response.

    I have contacted the guys I bought the Air Rifle from and am in the process of getting a “return authorization” from them (not Pyramid fwiw).

    Thanks again for your advice !

    Now, if I could ask you another quick question related to this “NEW” Rifle (Crosman AS2250XT)…

    …in the process of firing the few shots I could, in an attempt to “sight-in” the scope…

    /article/All_about_scopes_Part_3_April_2005/22

    …I was never able to bring the shots far enough to the left to line up vertically with the top “aim point.” In fact, with the scope “windage” adjustment ALL THE WAY to the left (maxed out) I could still only group shots an inch or so to the right of a vertical line between the top and bottom “dot”.

    So…from reading some of your other blogs about sighting a scope I’m guessing that I either need to use some sort of “shimming” method…OR…use “adjustable scope mounts” to bring it further left and accomplish the “sighting-in”.

    From reading your comments about “adjustable scope mounts” and the initial difficulty of getting them right…I have to say that for a novice like myself (not to mention the added expense) this option is somewhat daunting.

    That leaves the “shimming” option I guess.

    However, tell me this…since I am going to be returning the “NEW” Rifle anyway…should I also return the scope…in the hope that with a “NEWER NEW” Rifle and Scope the problem will hopefully resolve itself ?

    Is this something I should be concerned with ?

    Should a NEW scope be THAT far off that I am looking at the 2 choices above to even get it in the ballpark ?

    Any advice you can offer on this would be greatly appreciated !

    Sorry if this is a bit off-topic for this thread.

    Thank you again for all your help !

    skyfisherman

  76. Skyfisherman,

    The person who gives you the return authorization should instruct you on what to return. Usually that want the entire package and all contents because they replace it with a sealed package. But let them tell you that.

    I can tell you have done your homework on this. The barrels in these Crosman guns are held in by a single screw and a barrel band, and you can often adjust them to get centered with the scope.

    If you are not yet reading the Crosman Forum, I would suggest you sign up.

  77. Hello, B.B!

    I have a Crosman Walther PPK/S air pistol. Just recently I was removing the CO2 cartridge and the clip from the pistol (so we can bring it back safely home from the cottage), only to notice a rattling noise from from the gun. Upon further shaking, a brass/copper seal/washer fell out from the pistol.

    What is this brass washer and where does it go on the pistol?

    Now when I try to install new CO2 cartridges into the air pistol, the gas escapes out from the barrel and out from the top of the canister where it is pierced.

    The canisters that I have bought do not have an o-ring on them. I have not tried to put oil on the canisters before intalling them into the gun. I have not put oil on the gun.

    What do I do??

    I just want to fire my gun! Please help!!!

    Thanks in advance!

    Justin

  78. Justin,

    It sounds like part of your gun has fallen out of place. If the gun is new, return it to the dealer for exchange or a refund. If it isn’t new, call Umarex USA for return instructions.

    http://www.umarexusa,com

    I’m afraid your gun has to be repaired.

    By the way, you said you didn’t put oil on your CO2 cartridge. You are supposed to put a drop of Crosman Pellegunoil on the ti[p of each new cartridge before you pierce it. I don’t think that caused this problem, which is a rare one, but please do it in the future. Your gun will last for years that way.

    B.B.

  85. Crosman Pellgunoil is a blended product. It has 20-weight non-detergent motor oil and an o-ring preservative blended to work best in a CO2 gun. That’s why Crosman sells so much of it and why it’s so widely used.

    You asked if there was an alternative, and I told you what it was. But with the alternative you don’t get everything.

    B.B.

  88. Stores in my neighborhood don’t see to carry the Crossman pellgun oil, but I have found something called LiquidFire, which is advertised as “paintball marker and o-ring lubricant.” It’s even red. Any idea is this is the same as the Crossman oil?

  90. B.B.! Great News, I finally found a store that has PELLGUNOIL! yes the “red oil” made by crosman. Of all places BIG 5, just a tip for desperate pellgunoil seekers- i just bought out 7 1/2 oz. worth of pellgunoil at my big 5. Not a guarantee but check your local big 5.

  91. B.B. I just bought a Crosman C11 BB Gun and i wanted to know how long is it safe to keep a charged CO2 cartridge in the gun without causing any damage to the seals or the whole gun in general?..thanks for your time

  93. thanks..but in the manual it says not to store the gun for a prolonged time while charged because it will wear the seals is that true because i don’t wan’t to loose velocity..also can i use Gold Cup Oil lubricant for paintball guns on my c11?

  94. C11,

    Please listen to B.B.'s advice. Your manual is written with attorneys looking over the shoulder of the manufacturer's and distributors. They don't want you to store a c02 cartridge in your gun because of liability.

    Unfortunately, this advice shortens the life of your seals since exposed to air without any seal (a co2 cartridge with pellgunoil on the top of your cartridge) will allow it to dry out, shrink and when you do install your next co2 cartridge it cannot help but leak air.

    Don't use Gold Cup Oil. Spend $2.99 and buy what your gun needs. See it here:

    /search-results-ext?q=pellgunoil

    In this instance, ignore the manual and take the advice of a very experienced airgunner that has been there, done that and got the teeshirts.

    Trust me, he knows. I know he knows because I've followed this advice and it works.

    kevin

  95. I have a question, seeing as the Crosman contatc form is broken.

    Do you know if there is any adverse effects to using Pellgunoil in a break-barrel rifle’s compression chamber?

    My area doesn’t seem to sell RMCOIL and I applied PellgunOil to my Quest 500X, The recommended of course but not sure if it’s going to cuase it any major damage?.

    Then I sort of realized on the back ot says do not use with RM breka-barrel series.=[.

  96. Shroker (Ghost),

    Crosman Pellgunoil is a miracle product for CO2 guns.

    Your breakbarrel needs differant lubes and oils. Here’s a link to part 3 of a series B.B. did on oiling a spring gun like yours. At the top of the article you can click on part 1, then go back and click on part 2, etc. to read this series in order. You’ll need to copy and paste this link:

    No i havent i just dont know what oil to use, i really dont wanna buy anything? is there something around my house i could use

  102. Steven,

    I strongly recommend the crosman pellgunoil. It's $2.99 and will last the lifetime of your 760. Here's a link:

    • You can buy pellgunoil at both Bass Pro shops and Cabelas in my area! There are also several gun stores which carry a good line of pellet and bb guns which have it in stock! So at least in the St. Charles county area of Missouri, it is readily available. Also, Pyramyd AIR has it!

  106. Greetings,

    I own a Daisy 15xt and was very happy with it, untill today, i hadn’t used the pistol for about a year because i was away and after lengthy preparations of creating a special homemade trap/target and moving to the country house to spend some nice time target shooting, i find that the CO2 i insert into the Daisy leaks completely after about 10 seconds, spraying all over the upper end of the pistol, this ruined completely my weekend. Should i try and find some of this pellgunoil, with this kind of leak? What do you think?

  109. Hey guys…I know you have answered this many times in many different forms…but my question is about the enigma call Pellgun oil! Since I cannot find it locally (in Detroit area) and do not want to wait for the shipping…I do have access to Gamo Oil. Is this the same as Pellgun Oil? The Gamo Oil box and container are strangely absent of any description of it's exact usage or ingredients…hmmmm…seems fishy to me. Based on everything you guys have posted before, Pellgun oil is either magic or one of the best marketing gimmicks since diamonds! This stuff is like printer ink!!! Soon they will give away the pellet guns for a few a bucks…but the Pellgun oil needed to make them work will cost about 6 grand a gallon like printer ink!!.

    Anyway…I have a 1975 Crosman 1400 Pumpmaster which has been flawless for many years, and stored for about 5 years without ever using any Pellgun oil. I just started shooting it again about two weeks ago and it seems absolutely perfect. Should I start using Pellgun Oil? or the at-the-ready mysterious Gamo oil?

    Then I have a brand new C11 Crosman bb pistol and have fired about 5 co2 cartridges so far. Then I read this blog. Pellgun or Gamo? Same?

    Thanks…simple a great blog btw.

    Guide me o'soothsayer!

  110. Grasshopper,

    There is a problem with Gamo oil. Thye guys at Gamo don't know about airguns, so they can change their specification for oil at a moment's notice. I use a bottle of Gamo oil for a bulk-fill CO2 target pistol of mine and it works well, but I cannot guarantee that what I bought 15 years ago is the same thing that you have.

    Crosman knows airguns and Pellgunoil never changes.

  112. Hi BB
    I have a Walther CP99 and the CO2 Cartridge doesn't last more than 24 shot at best then it became very weak, is it a bad CO2 cans or something is defected in my gun

    Thanks
    Hesham

  113. Hey BB,

    I have a Walther CP99 Compact air pistol. I was just wondering what would happen if I don't use pellgunoil on the co2? Also how do I oil the side rails and would I use pellgunoil for that also?

    – Nate

  114. Nate,

    If you don't use Pellgunoil on every powerlet you airgun will continue to operate fine for a while. But it will eventually leak, because the seals are dry. It might take a year for this to happen, but it will eventually happen.

    Yes, you can use Pellgunoil on the side rails of your gun. It is made from motor oil and is a lubricating type of oil.

  115. Hi, I have a Crosman 2260 and i encountered a gas leak on my gun, so I researched the certain approaches I could take in taking care of the problem. When i first got the gun, i bought Crosman Pellegun Oil and has used it on every cartridge. I read the manual and this blog about fixing the problem. So I put a drop of the oil on the O-Ring and the cartridge. I fired the gun and waited for the leak to stop, but it hasn't. Does that mean I need to reseal the gun? Much Thanks.

  116. David,

    Yes, your gun needs a new seal. Chances are, it needs just the face seal — a flat membrane that seals the tip of the CO2 cartridge when it is pierced. Over-tightening the piercing screw or cap can cause this seal to tear.

    B.B.

    • Mike,

      Just put a drop of Pellgunoil on the tip of the cartridge and then install it in the gun in the regular way.

      You have landed on a report that is 9 years old. I have written a lot more about this over the years — including showing pictures of how it is done.

  118. I live in Nl. Canada’s most eastern province and usually the hardest place in Canada to find things . About a month ago Walmart here had lots of the Pellgunoil ,so I am thinking Walmart would carry it in all their stores ,maybe the guys were looking in the wrong place,Doug
