Made in the USA Special formulation for use with high compression CO2 gas and airgun seals, moving parts and pump actions. Cleans, lubricates and protects metal. Special formulation improves performance on a well-used airgun. See operating instructions in your manual before using. Crossman recommends a drop on the tip of every third AirSorce (88 gram) cartridge to oil the seals inside the gun. If you do that, your gun will hold gas for years and years.
