Im a little confused, well a great amount confused!

Hey guys. I know and fully understand that Green Gas IS PROPANE!!! So no need to flame me on this. But, I have been reading the forum about I forget who but they are collecting data on GBB failures. Many/all people that have been using propane on their GBB has been broken but either slide malfunctions or internal failures. But, however the people that have been using Green Gas on their airsoft guns have had absolutely no problems with it. I know that they are the same thing but even so, the same guns, the same problems. I will be using propane by using the AI Propane adapter. I have nt yet bought my airsoft gun but I am planning to buy a KJW Beretta M9 (Silver, Full metal Edition) and have heard that one person was using propane and the back of his metal slide cracked! I know that some airsoft guns are lemons but this is infact a repetitive problem by using propane. So to sum it up, I would like to know, why do the guns malfunction under the influence of propane and not green gas becuase they are the exsact same thing!? And what should I use on the M9? Thanks...
P.S. Please do not flame.

Maintaining your GBB has more of an effect on its life than whether you use green gas, propane or duster. I may be wrong but I was under the impression that the majority of "green gas" products have some sort of lubricantadditive to it. That in itself could help expand its life. However, I think that the more likely scenario is that you've just discovered a statistical anomaly. I don't think that there are enough constants in the data that has been provided so far, to truly draw a conclusion that GBB's last longer on green gas than propane.

Major difference between Green Gas and Propane is that Green Gas has Silicone (lubricant) in it. If someone uses Propane and doesn't properly lubricate the gun, that will cause problems.

I don't know if it would go as far as cracking a slide though.

Also, consider the cost of running a gun on Green Gas:

- It's harder to get
- It's more expensive

The likelihood that you'd put nearly the volume of Green Gas through a GBB that you would with (readily available, very cheap) propane is HIGHLY unlikely...

Chances are, if you put the same number of shots on Green Gas through a gun as you did with properly lubricated propane, you'd get very similar results (time will tell though, I suppose)

It is the general impression that Japanese GBBs are designed to work only on HFC134a and not fuel propane or airsoft packaged propane (Green Gas).

However, GBBs in general aren't exactly reliable which is why I'm trying to collect usage data on failures as well as information on GBBs which haven't yet failed. The information on GBBs which haven't failed is useful as it puts failures in context. Having a huge list of failures and not having any idea of working GBBs in the market can paint an unfairly grim picture.

I ask about propane usage because I suspect that green gas usage in Canada has declined a fair bit. Still I'm interested in the history of GG use because a lot of GBBs have been run on it.

Thanks for your replies. I guess the difference is that people with GBB's do not maintain their gun by using oil. To my understanding and knowlegde, if I put silicone oil it will keep my GBB running smoothly. Thanks, I appreciate it. I will be buying a AI propane adapter and silicone oil from AI soon.
