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.
Untreated Fuel Leads to Poor Engine Performance
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
Treated Fuel Delivers Maximum Performance
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
• hydrocarbons (HC) up to 15%
• carbon monoxide (CO) up to 26%
• nitrous oxides (NOx) up to 17%
• Restored power and performance
• Reduced need for costly higher octane fuel
• Reduced noise from carbon rap and pre-ignition
• Better drivability
• Smoother operation
AMSOIL P.i. works as an “emissions passer.” It is ideal for use prior to emissions inspections.
Unsurpassed Deposit Clean-up
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 or
back side of the valves. As deposits increase, they
restrict airflow and alter airflow patterns in the cylinder.
The deposits disrupt the balanced air/fuel ratio by
momentarily absorbing and releasing fuel, and they can
cause valve sticking by getting in the way of the valve
stem and guide. Deposits also restrict proper seating,
and the valves may be burned. Intake valve deposits
cause lost engine power, increased emissions, poor
engine efficiency and potential valve failure.
Combustion Chamber Deposits form on the top of the pistons
and on the cylinder heads. They increase compression
and absorb heat during combustion to later release it during
the intake cycle. In some engines with tight squish domes,
combustion chamber deposits cause the piston to actually hit
the cylinder head. This is referred to as combustion chamber
deposit interference or “carbon rap.” Combustion chamber
deposits also flake off as they get large, and these flakes can
get trapped between the valves and valve seat, resulting in
compression loss, difficult starting and rough idle.
Higher compression and stored heat cause increased intake
fresh charge temperatures and the increased likelihood of
pre-ignition “knock” or “pinging” when the fuel spontaneously
combusts prior to spark ignition. This increases emissions
and 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 retarded
timing. Higher octane fuels of 4-5 octane numbers can be
used to help prevent knock, an effect called “octane requirement
increase.” As a vehicle ages, more expensive higher
octane 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 higher
octane fuels are less necessary for peak performance.
Maximum Fuel Economy
AMSOIL P.i. maximizes fuel efficiency by dissolving and removing
fuel system deposits and other contaminants for improved
power 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.
DANGER: Combustible. Harmful or fatal if swallowed. Harmful if inhaled. Skin and eye irritant. Read precautions on container before use.
