Product Description Torco V-Series SAE 50 "ST" Motor Oil Bottle - 1 liter, (Case of 12) are formulated using highly refined petroleum base stocks and Torco's race proven MPZ additive providing better cooling, cleaning, ring seal, deposit control and anti-wear protection. It maintains viscosity and provides thermal stability under high temperature environments. The V-Series is specifically formulated for Harley and custom v-twin engines. It is recommended for use in early model air cooled v-twin engines where specified. It is commonly used in Harley (pre-1984: Knuckle, Pan, Shovel) and other early model custom v-twin applications. It meets or exceeds: JASO MA / API SG. Amazon.com Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance.SAE 50This oil has a weight of SAE 50, meaning it has a single SAE viscosity rating of 50 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle.Conventional Motor OilThis oil is a conventional motor oil, meaning it is refined from crude oil or petroleum products. Conventional motor oils may or may not have additives included after refining. Conventional motor oils are more versatile than synthetic or hybrid motor oils, because they are suitable for use with nearly all types of modern vehicle engines, from cars and trucks to motorcycles, ATVs, farm equipment, and more.
