Improves fuel mileage an average of 2.3% and up to 5.7%. Reduces emissions such as hydrocarbons (HC) up to 15%, carbon monoxide (CO) up to 26% and nitrous oxides (NOx) up to 17%. Restores power and performance. Reduces the need for costly higher octane fuel. Reduces noise from carbon rap and pre-ignition. Offers better vehicle drivability and smoother operation.
A vehicle demonstrates its best efficiency and engine performance when it is new. As the engine ages, its performance suffers from gasoline fuel-generated deposits that form on the fuel injectors, intake valves and combustion chamber. Additives are required to control deposit formation.
Today's fuels, however, lack sufficient treatments of either enough additives or high quality additives. Fuel system deposits result in the following:
• Lost fuel economy
• Lost power and poor throttle response
• Failed emission tests
• Poor drivability - surging, hesitation, stalling, rough idle
• Engine knocking (pinging) and rap
• Difficult starts
AMSOIL P.i. is the most potent gasoline additive available today. As a concentrated detergent, it is unsurpassed in cleaning combustion chamber deposits, intake valve deposits and port fuel injector deposits. AMSOIL P.i. helps maintain peak engine efficiency, fuel economy, power and drivability in newer low mileage engines. In engines with accumulated deposits, testing showed AMSOIL P.i. provided the following clean-up benefits after only one tank of gasoline:
• Improves fuel mileage an average of 2.3% and up to 5.7%
• Reduced emissions
Port Fuel Injector Deposits form after the engine has been shut down and there is no gasoline flowing through the injectors. During this "hot soak" period the injectors heat up and the gasoline remaining in the injectors degrades and forms deposits. This can happen very quickly with the use of poor quality gasoline and short trip driving. Because the clearances within the injectors are extremely tight and injectors must deliver precise amounts of "atomized" fuel, even small amounts of deposits can cause injectors to malfunction. Fuel flow is reduced and spray patterns are disrupted, decreasing engine efficiency, power and fuel economy, while increasing exhaust emissions.
Intake Valve Deposits form on the intake side orback side of the valves. As deposits increase, theyrestrict airflow and alter airflow patterns in the cylinder.The deposits disrupt the balanced air/fuel ratio bymomentarily absorbing and releasing fuel, and they cancause valve sticking by getting in the way of the valvestem and guide. Deposits also restrict proper seating,and the valves may be burned. Intake valve depositscause lost engine power, increased emissions, poorengine efficiency and potential valve failure.
Combustion Chamber Deposits form on the top of the pistonsand on the cylinder heads. They increase compressionand absorb heat during combustion to later release it duringthe intake cycle. In some engines with tight squish domes,combustion chamber deposits cause the piston to actually hitthe cylinder head. This is referred to as combustion chamberdeposit interference or “carbon rap.” Combustion chamberdeposits also flake off as they get large, and these flakes canget trapped between the valves and valve seat, resulting incompression loss, difficult starting and rough idle.
Higher compression and stored heat cause increased intakefresh charge temperatures and the increased likelihood ofpre-ignition “knock” or “pinging” when the fuel spontaneouslycombusts prior to spark ignition. This increases emissionsand may cause engine damage. Many of today’s cars have “knock” sensors that adjust spark timing to prevent knock.
Although audible knock is controlled, power is lost from retardedtiming. Higher octane fuels of 4-5 octane numbers can beused to help prevent knock, an effect called “octane requirementincrease.” As a vehicle ages, more expensive higheroctane fuel is needed to keep it operating at peak performance.By cleaning combustion chamber deposits, knock is controlled,power is restored, fuel economy increases and higheroctane fuels are less necessary for peak performance.
Maximum Fuel Economy
AMSOIL P.i. maximizes fuel efficiency by dissolving and removingfuel system deposits and other contaminants for improvedpower and overall performance.
Treat one full tank of gas up to 20 gallons with one bottle of P.i. For very large gas tanks, partially fill to 40 gallons and treat with two bottles of P.i. Using more than two bottles per treatment is not recommended. Treat gas every 4,000 miles or 100 hours of service. P.i. helps pass emission tests by running one tank of treated fuel through the engine prior to testing. Safe for use with catalytic converters, oxygen sensors, oxygenated gas and 10 percent ethanol blended gas. Not recommended for two-cycle engines.
