Propane vs green gas

[Theboy]

Alright so im new to gas thinkin of gettin one. Ive done a search on this site for this subject and did not find one (if there iss one please direct me to it), i did other searches on th e web found some that said green gass and propane are the same just no lube in propane. Anyways is this true? And is propane safe for guns that take green gas stock or do i need to mod?

For the most part it is the same, but like you said green gas has silicone oil in it already and propain you have to add it. Another difference is that propain needs and adaptor but propain is easier to find but it dose smell really bad.

What keasop is saying is true. I personally use propane in all my pistols, it's cheaper and easier to find. Green gas is pretty much disappearing, plus a bottle of propane will last quite a long time compared to the green gas cans. Trust me, all you have to do is keep the gun and the mag seals lubed, and you'll be good to go.

I have been using propane exclusively, unless in a pinch and someone loans me some green gas, for at least three years. Some people see green gas as a bonus due to it already having silicone lubricant for your o-rings already mixed in and absent the foul odor of propane. Problem is though that a lot of green gas puts so much lube in the gas that it has blown onto my hopup buckings and made them seemingly useless. Green gas usually runs around $15 for only 8oz versus ~$3 for 16oz of propane. Another thing to consider is that some magazines have their fill valve seated fairly far down into the base of the mag like most 1911 MEU mags and some green gas cans don't have a long enough fill spout to reach it. Despite the ~$20 propane adapter and having to add your own oil seldomly, propane pays off in the long run in a BIG way. Esecially for us avid pistol users and GBBR fanboys.

green gas is better for guns overall... it is a lower pressure than propane it has perfumes in it and it has lubrication also. lower pressure is better for a pistol over a very long period of time, the lubrication takes the extra work out of having to add silicon to your nozzle for every time you fill your gun, the perfume helps keep the smell down... so when i test a gun at home i use it so my mom dose not get mad at me... but you will have to pay for it. propane is much cheaper in the long run... I actually tend to mix them and put a little of both in to get the benefits of both the higher fps of propane and the lubrication of green gas but i only do that with guns that can handle it Tokyo Marui guns are not made for propane or even green gas for that matter they are supposed to be used with duster gas but green gas is what I use in mine.... thats all the knowledge I am ready to put down for now...

I believe Airsoft Innovations ran tests confirming that green gas is in fact propane with oil added to it. I've also read that KWA has done tests stating that propane varies from batch to batch depending on where its made. The chemical they add to produce the odor to propane can vary in strength and supposedly if to much is in a propane canister it can degrade certain parts in your GBB. Using propane in a KWA will void the warranty and they say use it at your own risk.

I tend to only use green because I don't like to field strip my guns for added maintenance and its not easy finding OEM parts for my guns. I'm also not interested in pushing my GBB's FPS in the CQB. 250 FPS might sound low but its accuracy that counts, not how hard your gun shoots.

Before I bought a GBB gun I did extensive research into green gas vs propane so I could confidently and safely use my gun.  Several 3rd party companies have done chemical analysis on green gas and have found it is simply propane with no "bitterant" and silicone oil premixed in.  I use a madbull propane adapter that lets me put silicone oil in the adapter so that as the gas goes through it and into my gun, it mixes and essentially creates "green gas".  The smell of flatulent is always there when you use propane, however it dissipates rather quickly (in my opinion) and the cost to benefit ratio of propane over green gas was the deal breaker for me. 

TL/DR:  Propane is green gas with oil, get a good adapter that lets you put oil in it, and you'll be good to go.

wow everyone agrees then lol... that propane with silicon spray on the seals... is the most effective way to go about with a gas gun

Im with Fenix.  I have the Madbull Propane adapter and it is easy just remove the cap and put in a couple drops and replace very simple.  I do think that green gas is more efficent though in the overall workings of my pistol.  But being on a budget the propane is the way to go for me.

LOl leave for a few days and i get a page on propane vs green XD. thx guys

Just for the record, I don't agree that propane and added oil is the best way to care for GBB. It really depends on the gun you own and if your comfortable with taking apart your GBB or not.

I agree with this statement.  There are guns at So Go Airsoft that I would only use Green Gas.  And there are others that I am not as worried about.  And I agree with knowing how to take care of a GBB.  That is very important with the propane.  And with the Green Gas it can also help.  But learn it properly.  Don't just go home and take things apart and not expect to have an issue pop up.  Alot of us do just that.  My issue is when people do that and come back in the store the very next day blaming us or the gun manufacturer for the gun failing.  When in fact that just put something back together wrong or used the wrong oil.

      Ok, I'm sorry I barely read any of the posts so I hope I don't repeat too much that's already been said. I'm going to major in a science that involves a lot of chemistry so I'm a big nerd when it comes to this kind of stuff. I always hear people talking about the propane vs. green gas issue so I have done an extensive amount of research and experimenting on this and have come to a not so surprising conclusion. I've found that green gas is propane based that is sort of infused with oil so that the oil to gas ratio isn't off and for every molecule of propane there is, there is a molecule of oil to back it up.
      Also during this research I found green gas is highly synthetic which can gum up your gas system faster or slower depending on the amount you use your gun. The more you use that gun it actually helps to kind of auto-clean the gun, if you don't use the gun much than your gas system is going to gum up so bad you won't be able even pull the trigger.
      Basically, green gas and propane mixed with a little silicone oil are the same things but if you use your gun extremely frequently green gas is the way to go and will probably save you in the long run. If you don't use your gun all that much, the cheap and easy way (propane mixed with silicone oil) is the way to go and your gun won't gum up very bad if let sit although if you go this route your gun will need more frequent cleanings.

Ok, then answer this. Why does FPS differ between green and propane if they are the same?

[j man 3]

green gas does not "gum up" your gun at all... propane is more likely to do that because it doesn't use any lubrication to remove worn paint or metal in the gun from continues usage.
