Red Line's 15W50 Synthetic Oil is the ultimate high-temperature protection in Red Line engine oils recommended for street use and is good for engines that regularly run very high oil temperatures. This oil is also best for engines that run large clearances such as air-cooled engines or large-displacement, all-out racing engines that see occasional street use. It provides 25 percent more viscosity in bearings than petroleum 20W-50s. 15W50 Synthetic Oil is not recommended for use in cold climates where temperatures are at or below 10 degree Fahrenheit and is not recommended for street use in production engines that see sustained oil temperatures below 225 degree Fahrenheit (those engines should use Red Line 10W-30 or 10W-40). Red Line's synthetic motor oils are designed to provide the highest protection, cleanliness and superior drain intervals with the lowest friction for your gasoline, diesel, motorcycle or marine engine. Red Line uses the most stable components available and formulates products for wear protection and friction reduction across a wide range of engine operating conditions. Red Line's products are unique because they contain polyolester base stocks which can withstand the tremendous heat of modern jet engines. These synthetics have a natural multi-grade property which allows our chemists to avoid bulking up an oil with unnecessary additive packages. Red Line Synthetic Motor Oils will provide better protection than a petroleum oil of the next higher viscosity grade under high shear conditions.
