The main purpose of gun oil is to lubricate the moving parts of the gun in order to reduce heat buildup. Gun oil is used to prevent cracking of the metal as well a wear and tear upon firing a rifle.
Oil is oil. Gun oils just have different additives.
That is where the bullet comes out of the gun.
Oil it with "Crosman Pellgun oil", "RWS OIL" or "Gamo Pellet gun oil" Wipe it down. DO NOT USE Household oil or 3-N-1 oil. They will damage the gun. Put a drop in the barrel and run a swab through the barrel. If it's a C02 gun then put a drop of oil where the C02 bottle fits into the gun and charge the gun. If it's a springer type of rifle, put a drop of oil in the oil hole in top of the rifle barrel or in the loading chamber. DON'T over oil the gun.
