Formulated for race engines, but compatible with passenger vehicles too.Amazon.comMotor 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-50This 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 OilThis 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 gas mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil. Racing OilRacing oils are designed for track cars and other types of high-compression vehicles intended for motorsports competition. They contain particular additives for increased engine horsepower and reduced friction on metal parts, and provide special protection for engines with high compression or higher horsepower. Racing oils usually include fewer detergents than regular conventional motor oils. Please note that many, if not all, oils labelled as racing oils are not street legal, and it is not recommended to put racing oil in a conventional passenger vehicle. Make sure to double-check the product label as well as the specifications of your vehicle to ensure proper usage.From the ManufacturerValvoline VR1 Racing Motor Oil - High Zinc Provides Race-Level Protection for Any Vehicle Valvoline offers a line of racing motor oils that are designed for the serious racer.
