STP (Scientifically Treated Petroleum) is an American brand and trade name for automotive aftermarket products, especially lubricants such as motor oil and motor oil additives. 

The actual "invention" of what is now known as "STP" was originally invented by German scientists during WW-2 as a response to Germany's need for lubrication of the German war-machine vehicles. It was alleged by WW-2 U.S. Army divisions in Africa that overtook German infantry vehicles (mostly of the original Volkswagen design) that the Germans employed "engine oil" that is now known as STP formulation full-strength in the VW air-cooled 4-cylinder engines, which successfully traveled through the hot African Desert war-front without seizing due to friction and extreme heat. How the German's original chemical synthesis formulation found its way to the U.S. after WW-2 is not known, but most likely came along with many of the other German inventions through the distribution of technology from the spoils of war.
