Royal Purple API-Licensed Heavy Duty SAE 40 High Performance Synthetic Motor Oil is fully synthetic - not made from crude oil like traditional motor oils. It's used to lubricate, clean, and cool engines with the utmost efficiency. 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. This oil has a weight of SAE 40, meaning it has a single SAE viscosity rating of 40 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. 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 gas mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil. Royal Purple Motor Oil Combines premium base oils with proprietary additive technologies to create high performance motor oils that optimize engine performance and provide superior protection. No special procedures are necessary when upgrading to Royal Purple. Royal Purple motor oil is fully compatible with mineral or other synthetic oils. Royal Purple recommends waiting until the manufacturer's first scheduled oil change in new gasoline engines before upgrading to Royal Purple. Royal Purple's API licensed motor oil delivers superior protection and improves performance in gasoline and diesel engines. Royal Purple's API SN licensed motor oil meets ILSAC GF-5 and Dexos1 performance requirements.
