Royal Purple Max-Atomizer fuel injector cleaner is a fully-synthetic, highly concentrated, high performance fuel injector cleaner. Specially formulated to solve problems with today's direct injection engines, it can be used with any type of fuel injection. Max-Atomizer contains highly concentrated polyether amine (PEA) detergents that quickly clean clogged and coked injectors, restoring 100 percent of injector flow. This will optimize injector spray patterns and better atomize fuel as it enters the combustion chamber. Enhance power and performance with Royal Purple Max-Atomizer fuel injector cleaner. Performance advantages include: * Restores and improves fuel economy * Stabilizes ethanol, which chemically breaks down to cause harmful effects to an engine * Maximizes horsepower * Improves responsiveness * Smoother idle * Quicker, easier starts * For use in both gasoline and diesel engines * Recommended for all ethanol blends * Reduces emissions, but will not harm vehicle emissions equipment * EPA / CARB compliant

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.

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.
