Horsepower satisfies the need for speed and can even add a little fun to the daily commute. But over time, carbon buildup and wear can cause engines to lose peak power output. Unacceptable. AMSOIL has the products to maintain peak horsepower in the vehicles you love, from race cars to powersport vehicles to daily drivers.
AMSOIL Signature Series Synthetic Motor Oil
Of course, prevention is the best medicine. AMSOIL Signature Series Synthetic Motor Oil can help stop horsepower loss before it starts. To begin with, our synthetic base oils have a lower coefficient of friction, resulting in less drag and energy loss from fluid friction. Their chemical purity and consistent molecular structure help the oil flow easier while maintaining a stronger molecular bond that is less susceptible to shearing when exposed to mechanical stress.
AMSOIL builds on those benefits to provide unmatched protection and efficiency. Robust anti-wear additives yield extra protection in metal-to-metal contact points. Improved detergency keeps passages free from sludge and deposits that rob horsepower. Plus, Signature Series is highly resistant to heat, helping to protect turbochargers from turbo coking that can lead to a loss in performance and eventual failure. In fact, Signature Series provides 75% more engine protection against horsepower loss and wear1 than required by the industry standard, extending the life of vital components like pistons and cams.
AMSOIL Signature Series Synthetic ATF
But not all horsepower loss happens in the engine. AMSOIL Signature Series Synthetic Automatic Transmission Fluid delivers maximum protection and horsepower output. It withstands the rigors of heavy towing, elevated temperatures and challenging terrain – providing reserve protection during heavy use and abuse. In winter climates, it remains fluid in sub-zero temperatures for efficiency and protection at startup.
Preventing sludge and wear is important for maximizing horsepower. Today’s transmissions pack in an enormous number of gears, clutch packs and narrow oil passageways that require a steady supply of high-quality fluid to function. Transmissions used for hauling or towing are subjected to enormous torque and increased heat, the number-one enemy of any transmission. Signature Series ATF handles heat so well, you can confidently double your vehicle manufacturer’s severe-service drain interval with guaranteed AMSOIL protection. Additionally, AMSOIL contains the optimal blend of additives to ensure the most power possible is transferred from the engine to the axle by helping eliminate slippage.
To demonstrate its capabilities in severe service, Signature Series ATF was installed in a fleet of Las Vegas taxi cabs and subjected to a 180,000-mile (289,700-km) severe-service test. The vehicles routinely endured demanding stop-and-go driving while loaded with passengers and cargo in extremely hot desert temperatures, placing tremendous stress on the fluid. Following 180,000 miles (289,700 km), a transmission was selected for analysis. An independent, third-party lab revealed the used AMSOIL Signature Series ATF resisted oxidation longer than required for new fluid to meet the Chrysler ATF+4 specification.
AMSOIL fuel additives can help ensure fuel is properly atomized in the combustion chamber for the most efficient combustion and maximized power output. They can also provide critical cleaning to intake valves in port-fuel injected engines and help eliminate the variability of fuel quality and ethanol content between stations and fuel brands.
AMSOIL P.i. is a deep-cleaning performance improver that aggressively cleans stubborn, power-robbing deposits from injectors, valves and the combustion chamber to help restore horsepower. P.i. is effective in port and direct injection systems and cleans the entire fuel system in one tank of gasoline.
We set out to demonstrate the power of P.i. through third-party testing using a 2016 Chevrolet* Silverado* with 100,616 miles (161,926 km) on the odometer. Prior to treatment with P.i., the truck was run on a chassis dyno and measured for horsepower output. The 5.3-liter gasoline direct-injection engine was then disassembled, photographed and reassembled. After a single tank of fuel treated with P.i. driving at highway speeds, the truck was strapped back to the dyno. It measured an astounding 14% improvement in horsepower.
The engine was disassembled once again to measure P.i.’s effect on deposits. P.i. significantly reduced deposits, helping restore peak power and performance.
AMSOIL Upper Cylinder Lubricant
An engine’s top-end is sparsely lubricated and prone to the development of performance-robbing deposits. It’s also highly susceptible to corrosion, an issue compounded by the prevalence of ethanol common in today’s fuel. AMSOIL Upper Cylinder Lubricant combats ethanol related issues like corrosion and provides critical lubrication to the upper cylinder region. The AMSOIL-exclusive formulation helps maximize engine power and performance while increasing engine life.
In addition, AMSOIL Upper Cylinder Lubricant’s unique formulation provides improved lubrication to fight piston-ring and cylinder wear, maximizing engine compression and horsepower. Those lubricity improvers also aid in protecting fuel injectors and other fuel-system components, helping ensure outstanding performance and long life.
How good is it? AMSOIL Upper Cylinder Lubricant outshines the competition, delivering 18% more lubricity than Lucas* and 20 percent more than Sea Foam* for better retention of horsepower and fuel economy.2
DOMINATOR® Octane Boost
AMSOIL DOMINATOR Octane Boost significantly increases engine response and power in all two- and four-stroke gasoline-fueled engines by increasing octane up to four numbers. Just one treatment reduces engine knock, improves ignition and helps fuel burn cleaner.
Octane Boost is recommended for all high-performance off-road and racing applications. It is also excellent as a lead substitute in collector automobiles, older off-road equipment and pleasure vehicles. DOMINATOR Octane Boost helps keep high-compression engines from pinging by boosting octane ratings and ensuring the engine’s timing remains at peak performance levels.
AMSOIL Motorcycle Octane Boost
AMSOIL Motorcycle Octane Boost increases octane for power and efficiency of your ride. It is designed to improve startup performance and eliminate engine ping and knock for increased power at low-rpm operation. Motorcycle Octane Boost also contains detergents that help combustion chambers and fuel delivery systems maintain cleanliness for optimum performance and power output.
