Royal Purple HMX high-mileage motor oil is specially formulated with robust zinc/phosphorous anti-wear additives and proprietary Synerlec technology to minimize aging and restore lost engine performance. It's chemically-enhanced to revitalize hardened seals, thereby reducing oil consumption common in higher mileage engines. Stout detergents remove engine deposits and maintain cleanliness to promote engine longevity. Royal Purple's advanced Synerlec technology provides exceptional film strength, which lessens friction for peak engine performance. HMX high-mileage motor oil offers outstanding oxidation resistance to safely extend oil drains; plus an ionic attraction to metal components to maintain a film of oil on engine parts, minimizing start-up wear.

Royal Purple Premium High Performance motor oil combines premium synthetic base oils with proprietary additive technologies to exceed protection and performance requirements of new modern engines. These often include smaller displacements, turbo chargers, gasoline direct injection (GDI), and start/stop systems. Modern gasoline direct injection (GDI) engines have achieved levels of power and fuel economy never before possible in passenger car engines. As a result, smaller engines operate at much higher loads across all engine speeds. This has caused increased wear in critical areas of the engine, and created a destructive phenomenon called low-speed pre-ignition (LSPI). The unique, state-of-the-art additive technology in Royal Purple High Performance engine oils is designed specifically to address these issues, and help engines maintain performance and reliability.

Royal Purple Duralec Ultra diesel motor oil is specifically formulated to maximize performance and meet the demands of today's heavy-duty engines. Duralec Ultra is fortified with a high level of zinc/phosphorus anti-wear additive, along with Royal Purple's proprietary Synerlec additive technology. Synerlec creates a tenacious ionic bond with metal surfaces, providing protection upon startup, and greatly increased film strength that helps to eliminate metal-to-metal contact, even under severe conditions. Additional performance advantages include: * Superior corrosion protection * Low coefficient of friction results in optimized fuel efficiency * Better wear protection * Natural solvency keeps engines cleaner than detergents alone * Oxidation and heat stability greatly extends oil drain intervals * Compatible with other mineral and synthetic motor oils * Reduces exhaust emissions * Mates engine parts * Will not harm seals * API warranty compliant * Recommended for 2- and 4-cycle diesels; including automotive, commercial fleet, and stationary industrial applications

Royal Purple Synfilm reciprocating 100 air compressor oil is a premium, high film strength, energy-efficient oil, that provides maximum performance in reciprocating air compressors. Synthetic lubricant excels in reducing wear and keeping discharge valves free of harmful carbon deposits. Synfilm contains Royal Purple's advanced Synerlac additive technology, which gives its lubricants their amazing performance advantages. The Synerlac forms a tough, slippery synthetic film on all metal surfaces. This proprietary film significantly improves lubrication by increasing the oil film's thickness and toughness, both of which help to prevent metal-to-metal contact. Royal Purple Synfilm reciprocating 100 air compressor oil displaces moisture from metal surfaces and protects all metals against rust and corrosion, while fortifying the oil against the detrimental effects of heat.

Royal Purple Max-Restore High Mileage cleaner is a highly concentrated, high performance fuel treatment that is specially formulated to solve performance problems typically found in higher mileage vehicles. It restores fuel economy, extends engine life, lowers emissions, and delivers maximum cleaning power. Max-Restore contains a high dose of polyether amine (PEA) and proprietary detergents that quickly clean stubborn, long-term deposits often found in high-mileage engines and provides a protective barrier to keep new deposits from forming. This optimizes the injector spray pattern and better atomizes fuel as it enters the combustion chamber, resulting in enhanced power and performance, reduced emissions, smoother idle, and quicker/easier starts. It also utilizes a friction modifier to reduce wear in the upper cylinder to help extend engine life and improve fuel economy.
