    New 'Numpty' questions on C02 pistol maintenance.

    Hi Guys,

    Collecting my first C02 pistol next week, a CP88 long barrel.

    I'm told a drop of Pellgun oil is needed on the top of the bulb every 3rd bulb.

    I've read all C02 have oil already, but only Crossman use it as a sales tool. I've bought 100 Umarex Co2, I assume they are good quality (if all co2 are not the same!)

    I've also seen I should use one of these as well every 4th bulb "Walther Maintenance CO2 Capsules".

    https://www.solware.co.uk/walther-ma...e-co2-capsules

    Is this all correct or am I being mislead?

    Thanks for some Co2 love

    I put a drop on every other bulb, but I don't know if it's entirely necessary.
    If I wanted to save a few quid I would look at other areas of my lifestyle first!

    No, I suspect you could buy several lifetimes worth of seals for that

    Umarex pistols dont need or like pellgun oil much.
    A drop on a capsule now and again is ok.

    Maintenance capsules are expensive and very messy.
    Not to be used indoors!

    I’ve used two of them in years and didn’t see real benefits.

    If not pellgun oil, I've seen you can use R/C car silicon shock oil, 10 weight.

    I have loads of silicon R/C oil as I've spent many years racing at clubs all over the place.

    Would R/C shock oil be a better option, rather than Pellgun in a Umarex pistol?

    Used to use Pellgun on my CO2 pistols, one tube lasts a long time
    I used to buy whatever was cheapest/best value in terms of CO2.
    The biggest problem with CO2 is leaving capsules in long term, that combined with no oil can apparently cause the seal to deform.

    Crosman used to put oil in years ago - but haven't for many years now.

    Pellgun oil lasts for ages, so not worth skimping IMHO - but if you want a cheaper alternative...try ATF - it's designed to both lubricate and keep seals & o-rings in good health (most other oils attack them).

    Personally I would be more worried about the shortage of Co2 we have according to BBC Breakfast. I just wonder how much they will be putting the prices of the capsules up now.

    Isn’t that food grade co2?

    Less is more. Like others I add a spot of oil on the top of the occasional bulb before it is pierced. I have come to wonder whether it actually has much benefit. The piercing pin on many pistols is tiny, so not much oil would get forced up by the CO2 onto the internal valve seal, most of the spot of oil probably sits on the neck/interface seal. That probably has some benefit in keeping that seal compliant. I know of one example where the interval valve seal of a CP88 was leaking and Pellgunoil cured it; not sure how it was administered to get a beneficial amount into the valve.

    Along with not leaving a Co2 cap in a gun for weeks, don't over tighten the piercing mechanism. On the CP88 pop in you Co2 cap and take up the slack with the knurled nut, that's all it needs. Closing the foot of the grip achieves the piercing. It's the overtightening of caps in pistols & revolvers that leads to the deformation of the seal & leaks.

    Top Tips from Paul.

    I always wrap my pistols before storage in their foam cases.
    Oil and foam can discolour finishes.
    Also stand the cases up rather than lay flat to avoid pressure rashes.

    Having done all of the things suggested here be aware that there are many exceptions to the rules.

    I have bought Umarex pistols that have been badly stored with co2 in ,and neglected but they look and shoot fine.
    I’ve bought Gallery Queens and new ones that shoot poorly or have other defects.

    Annoying!
