• Popular in turbocharged applications.
• For wider bearing clearances and racing engines that see occasional street use.
• 25% more viscosity than petroleum 20W-50s.
• Not recommended for use in cold climates (-20°C/-5°F for 20W50).
• Recommended for API SN/SM/SL/SJ/SH/SG and ACEA A3.

Product Description ------------------- Red Line's 20W50 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. It 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. Provides 25% more viscosity in bearings than petroleum 20W-50s. This 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 sustained oil temperatures below 225°F (those engines should use Red Line 10W-30 or 10W-40). Red Line uses the most stable components available and formulates products for wear protection and friction reduction across a wide range of engine conditions. Red Line'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. Red Line Synthetic Motor Oils are designed to provide the highest degree of protection and cleanliness for your engine. Red Line uses the most stable synthetic components available and formulates their products for wear protection across a wide range of operating conditions. Red Line 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 basestocks have a natural multigrade property, which means that large as of unstable polymeric thickeners are not required to manufacture our multigrades. Red Line Synthetic Motor Oils will provide better protection than a petroleum oil of the next higher viscosity grade under high shear conditions. .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 20W-50 ---------- This oil has a weight of SAE 20W-50, meaning it has an SAE viscosity rating of 20 in cold temperatures and a 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. Full Synthetic Oil ------------------ This oil is a full synthetic oil, meaning crude oil is not used in making it. Synthetic oil can be used in vehicle engines instead of motor oils refined from crude oil, and often provides superior mechanical performance over traditional motor oil, including increased mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil.
