LPG used for cooking and such is not very "clean". It's suggested that the additives, and/or the unrefined crap is bad for your pistol. I personally have not witnessed this myself. Even if it is true, regular cleaning and lubrication is key; even if your using green gas. There could be some impurities that eat o-rings, rubber seals, or cheap plastic parts over time; but if it's true, it takes a long time. Green gas is apparently heavily refined, with good silicone oil pre-added. Unfortunately their canisters are not on par. I find it hard to believe that green gas is worth the 4x plus cost of propane.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
