AMSOIL P.I.® Performance Improver

Maximum Deposit Clean-up for Optimal Engine Performance

AMSOIL P.i. excels in maximum deposit clean-up, utilizing potent additives to target and combat prevalent engine deposits, minimizing their impact effectively.

Enhancing Engine Performance with P.i. Fuel Additive

Fuel injector deposits pose a significant challenge, particularly in the advanced engines using gasoline direct-injection (GDI) for enhanced power and fuel efficiency. These injectors, situated within the high-pressure and high-temperature combustion chamber, are susceptible to deposits, leading to increased soot levels. GDI engines produce substantially more soot than traditional port fuel injectors (PFI), impacting efficiency and contributing to various issues.

Injector fouling can result in reduced efficiency, power, and fuel economy, while also escalating exhaust emissions and causing problems like poor starting and rough idle. In addressing these concerns, the P.i. fuel additive proves to be a crucial solution. Rigorous testing demonstrates that P.i. effectively eliminates stubborn deposits, restoring GDI fuel injectors to a remarkable 40% flow rate improvement after just one tank of fuel. Thus improving fuel economy.

In the pursuit of optimal engine performance, count on P.i. to combat injector deposits and ensure your GDI engines run smoothly, efficiently, and with reduced emissions. Choose P.i. for cleaner, more powerful, and fuel-efficient operation.

Restoring Power with P.i.: Unveiling a 14% Increase in Horsepower

Revitalize your engine's performance with P.i., as proven by our third-party testing on a 2016 Chevrolet Silverado. Before treatment, the 5.3L GDI engine underwent dyno testing, revealing baseline horsepower. After a single tank of P.i.-treated fuel during highway driving, the dyno recorded a remarkable 14% surge in horsepower. Our disassembly and inspection process showcased the impactful cleaning effects of P.i. on injectors and cylinder heads. Witness the substantial restoration of power and efficiency with P.i.'s potent performance.

Preventing Power Loss and Engine Inefficiency

Intake valve deposits can significantly impact engine performance by altering airflow patterns and disrupting the air/fuel ratio. These deposits, which absorb and release fuel, may lead to valve sticking and potential failure. Addressing these issues is crucial as they result in decreased power, reduced efficiency, and increased exhaust emissions. The solution lies in using P.i., a product that effectively prevents and removes deposits, ensuring clean and unrestricted valve movement for optimal engine function.

The Impact of Combustion Chamber Deposits on Engine Performance

Combustion chamber deposits play a crucial role in engine performance, and understanding their effects is essential for maintaining optimal functionality. These deposits, formed during combustion, can elevate compression levels and absorb heat, only to release it during the intake cycle. However, this seemingly innocuous process can lead to detrimental consequences for the engine.

Carbon Buildup and Its Consequences

The accumulation of deposits in the combustion chamber can have severe repercussions. In certain cases, these deposits may cause the piston to collide with the cylinder head, a phenomenon aptly termed "carbon rap." Moreover, these deposits can become lodged between valves and valve seats, resulting in compression loss, which, in turn, contributes to challenging starting and rough idling.

Preventing Pre-ignition "Knock"

One of the critical issues arising from combustion chamber deposits is the increased likelihood of pre-ignition "knock" or "pinging." This occurs when the fuel spontaneously combusts before the scheduled spark ignition, leading to elevated emissions and potential engine damage. While many vehicles incorporate sensors to adjust spark timing and control audible "knock," this can still result in power loss and decreased engine efficiency due to delayed timing.

Mitigating the Impact

To counteract the negative effects of combustion chamber deposits, proactive measures are essential. Employing products such as P.i., specifically designed to target and eliminate these deposits, can yield significant benefits. This solution not only helps restore power but also plays a pivotal role in controlling knock, improving fuel economy, and diminishing the reliance on higher-octane fuels.
