AMSOIL PI PERFORMANCE IMPROVER ADDITIVE (12oz – 355ml) APICN

Maximum deposit cleaning

AMSOIL P.i. features additives that attack the most common forms of engine deposits and limit their effects.

Removes fuel injector deposits

Most new engines feature gasoline direct injection (GDI) to increase power and improve fuel economy. These injectors sit inside the intense heat and pressure environment of the combustion chamber, making them particularly vulnerable to deposits. Excessive pressure combined with incomplete fuel combustion can lead to dramatically increased levels of soot (particulates). Direct injection typically creates 30 to 40 times more soot than conventional port fuel injectors (PFI). Even a minimal amount of injector fouling can lead to increased emissions and wear and reduced power and fuel economy.

Fuel injector deposits:

• Reduce performance, power and fuel economy
• Increase exhaust emissions
• Contribute to poor starting and rough idling

P.i. removes stubborn deposits and keeps injectors working as they should. Tests show that P.i. restored GDI fuel injectors to a 100 percent flow rate after use in a single tank of fuel.2

Fights intake valve deposits

Valve deposits alter or restrict airflow patterns into the cylinder. They upset the balanced air/fuel ratio by absorbing and releasing fuel. Deposits can also cause valve sticking by interfering with the valve stem and guide.

Intake valve deposits:

• Reduce power and efficiency
• Increase exhaust emissions
• Cause potential valve damage

P.i. helps keep valves clean and moving freely.

• Restores power and performance
• Reduces the need for expensive higher-octane fuel
• Reduces carbon rap noise and pre-ignition
• Controls pre-ignition “pinging”
• Improves fuel economy
• Fully compatible bottle with capless fuel systems.

Cleans combustion chamber deposits

Combustion chamber deposits increase compression and absorb heat during combustion. Later, they release this heat during the intake stroke. In some engines, deposits can cause the piston to actually strike the cylinder head – a process known as “carbon rap”. Deposits can also break off and become trapped between the valves and valve seats, resulting in loss of compression.

Higher compression and stored heat increase the likelihood of pre-ignition, when fuel ignites by itself before spark ignition. This increases emissions and can cause engine damage. Most vehicles have sensors that adjust ignition timing to prevent knocking. Although audible “knock” is controlled, power is lost through retarded timing and engine efficiency suffers. Higher-octane fuels can be used to prevent the phenomenon. As a vehicle ages, more expensive higher-octane fuel is required to keep it running at peak performance.

Combustion chamber deposits:

• Increase the likelihood of “carbon rap”
• Contribute to compression loss, hard starting and rough idling
• Increase the likelihood of pre-ignition “knock” or “pinging”

P.i. fights combustion chamber deposits which helps restore power, control pre-ignition, increase fuel economy and reduce the need for higher-octane fuels.

Maximum fuel economy & reduced emissions

AMSOIL P.i. maximises fuel efficiency by dissolving and removing deposits and other contaminants for improved power and overall performance. Improves fuel mileage by up to 5.7%.1

P.i. works as an “emissions-restoring additive”, bringing emissions back to normal levels. Running a tank of P.i.-treated fuel through your engine helps you pass emissions tests.

P.i. also reduces the following types of emissions1:

• Hydrocarbons (HC) up to 15%
• Carbon monoxide (CO) up to 26%
• Nitrogen oxides (NOx) up to 17%

Packaging compatible with capless fuel systems

Many new vehicles have replaced traditional fuel caps with capless systems. The threads on most bottles restrict the opening of the flap inside the filler neck and also make it difficult to remove the bottle. The P.i. bottle is fully compatible with capless fuel systems.

RECOMMENDATIONS

• For use in petrol cars and trucks.
• Treats up to 113 litres (30 gallons). Add the entire bottle to the tank when filling up.
• For best results, clean the fuel system with P.i. every 7,000 kilometres.
• For large fuel tanks, treat with two bottles of P.i. Using more than two bottles per treatment is not recommended.
• Safe for use with catalytic converters, oxygen sensors, oxygenated fuel and fuel blended with up to 15% ethanol.
• Do not use with diesel fuel or E85 fuel or in two-stroke engines.
