Red Line 11504 SAE 15W50 Fully Synthetic Motor Oil - 1 Quart

15W50 Synthetic Oil is the ultimate high-temperature protection in 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% 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°F or -12°C and is not recommended for street use in production engines that see oil temperatures below 225°F (those engines should use 10W-30 or 10W-40). uses the most stable components available and formulates products for wear protection and friction reduction across a wide range of engine operating conditions. s products are unique because they contain polyol ester base stocks, the only lubricants which can withstand the tremendous heat of modern jet engines. These synthetics have a natural multigrade property which allows our chemists to avoid bulking up an oil with unnecessary additive packages. Synthetic Motor Oils are designed to provide the highest degree of protection and cleanliness for your engine. uses the most stable synthetic components available and formulates their products for wear protection across a wide range of operating conditions. lubricants contain polyol ester basestocks, the only lubricants which can withstand the tremendous heat of modern jet engines, which makes our motor oil a necessity to properly lubricate a turbocharger or hot-running engine. The synthetic base stocks have a natural multigrade property, which means that large amounts of unstable polymeric thickeners are not required to manufacture our multigrades. Synthetic Motor Oils will provide better protection than a petroleum oil of the next higher viscosity grade under high shear conditions.
