Royal Purple HPS 5W-20 High Performance Street Synthetic Motor Oil with Synerlec - is 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. This oil has a weight of SAE 5W-20, meaning it has an SAE viscosity rating of 5 in cold temperatures and a rating of 20 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 HPS Series motor oil is specifically formulated to maximize performance and meet the demands of high performance and modified engines. It is fortified with a high level of zinc/phosphorus anti-wear additive and Royal Purple's proprietary Synerlec additive technology. This unique blend enables HPS to outperform leading synthetics and conventional lubricants. The available viscosities include 5W-20, 5W-30, 10W-30, 10W-40 and 20W-50. HPS is recommended for vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection. Royal Purple's HPS Series of motor oil responds to increased pressure with increased viscosity. It's advanced additive technologies, such as Synerlec improves the condition of metal-to-metal contact under severe conditions for greater protection.
