Royal Purple® XPR 3.1 with Synerlec® SAE 10W-40 Extreme Performance Racing Oil Quart Bottles

Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. This oil is fully synthetic; crude oil is not used in making it. Synthetic oil often provides superior mechanical performance over traditional motor oil, including increased gas mileage and reduced engine wear at extreme temperatures. 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. This oil has a weight of SAE 10W-40, meaning it has an SAE viscosity rating of 10 in cold temperatures and a rating of 40 at normal operating temperature. Racing 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. Royal Purple Extreme Performance Racing oil is extremely popular in all forms of motorsports, from NASCAR and NHRA to the World of Outlaws and the Bonneville Salt Flats. Professional engine builders and race teams have found increased horsepower and engine life by using Royal Purple extreme performance racing oil. Available in many grades for every type of racing. It contains Synerlec technology.

• Synerlec Additive Technology - Synerlec, Royal Purple's proprietary, additive lubricant technology, is the cornerstone of RP's entire product line. It creates an ionic bond that adheres to metal parts to provide continuous protection even at start-up and strengthens the oil to provide unparalleled performance and protection.
• Can I Use Racing Oils in My Street Car? - Yes. Royal Purple’s XPR racing oils are fully formulated engine oils with complete additive packages needed for long-term use.
• Using XPR with Exotic Fuels - Royal Purple's lubricants can be used with exotic fuels. For the best protection, Royal Purple has formulated its XPR 5W-20 and XPR 10W-40 specifically with this in mind. These two oils are formulated to combat fuel emulsification to hold up even better than Royal Purple’s other racing oils in alcohol and methanol applications.
• Compatible with Coated Bearings - You may use Royal Purple HPS or XPR engine oils on newly coated bearings without needing a mineral oil break-in period.
• Reduces Oil Temperature Under Load - In most instances, vehicles with properly functioning cooling systems can reduce oil temperatures by 5-20°F by using Royal Purple
