  • Royal Purple Max-Clean Fuel System Cleaner and Stabilizer 11722

    Max-Clean is a state-of-the-art fuel system treatment that cleans injectors, restores fuel economy and reduces both engine buildup and tailpipe emissions. Max-Clean’s proprietary technology targets both the intake system and combustion chamber and is effective on the entire spectrum of engines on the road, whether they are new or old, gasoline or diesel, naturally aspirated, turbocharged or supercharged. After multiple product fleet tests were conducted on various makes and models of vehicles, Royal Purple found that after, as little as one Max-Clean treatment can improve fuel economy an average of 3.2 percent and increase horsepower an average of 2.6 percent. Reduces Hydrocarbon, NOx and CO emissions (on average 12, 13 and 18-percent respectively). Prevents rough idle, hesitation and stalling. Prevents premature spark plug fouling. Reduces deposit-related engine knocking and pinging. Deposit build-up is a natural consequence of fuel combustion, unfortunately these deposits can have a significant effect on the performance and reliability of your engine. With Max-Clean, Royal Purple has developed a product that in most cases can bring engine surfaces back to like-new clean, restoring once-lost fuel economy and performance.

  • Royal Purple 18000 Max Atomizer Fuel Injector Cleaner - 6 oz.

    Royal Purple’s Max-Atomizer is a fully-synthetic, highly concentrated, high performance fuel injector cleaner. It is specially formulated to solve problems with today’s direct injection engines, but 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% of injector flow. This optimizes injector spray patterns and better atomizes fuel as it enters the combustion chamber. The result is improved fuel economy, enhanced power and performance, reduced emissions, smoother idle, and quicker / easier starts. Max-Atomizer is the only fuel injector cleaner that also stabilizes ethanol, which chemically breaks down to cause harmful effects to an engine.

  • Royal Purple 36130-6PK HPS 10W-30 Synthetic Motor Oil with Synerlec Additive Technology - 1 qt. (Case of 6)

    Royal Purple HPS 10W-30 High Performance Street Synthetic Motor Oil with Synerlec 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. This oil has a weight of SAE 10W-30, meaning it has an SAE viscosity rating of 10 in cold temperatures and a rating of 30 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 p...

  • Royal Purple ROY11748 HMX SAE 5W-30 High-Mileage Synthetic Motor Oil - 5 qt.

    Royal Purple HMX SAE 5W-30 High-Mileage Synthetic Motor Oil, 5 quart is specifically designed to minimize wear and restore lost performance in engines with more than 75,000 miles. Formulated with robust zinc/phosphorus anti-wear compounds combined with Royal Purple's proprietary additive technology Synerlec, HMX is chemically enhanced to revitalize hardened seals, reducing oil consumption common in high-mileage engines. In addition, HMX is fortified with stout detergents to remove engine build-up and deposits, maintain cleanliness and promote engine longevity. The advanced Synerlec technology in HMX provides exceptional film strength, reducing friction and metal to metal contact for peak engine performance. It also provides outstanding oxidation resistance to safely extend oil drain intervals, and an ionic attraction to metal surfaces, providing protection and minimizing wear at start-up. Engineering formulations is a balancing act as engine oil has several key functions to perform. Higher mileage engines require a shift in this balance in certain regards as compared to new engines, such as anti-wear, detergency and preserving and restoring seal elasticity. Recommended for gasoline passenger car and light-truck engines beyond 75,000 miles, HMX can safely extend oil drain interval...
