Reformulated for greater potency
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 PI 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 PI helps maintain peak engine efficiency,
fuel economy, power and drivability in newer low mileage engines. In engines with
accumulated deposits, testing showed AMSOIL PI 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 PI 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
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 PI 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 every 4,000 miles or 100 hours of service. One bottle treats
20 gallons of gas. Do not treat and run more than 40 gallons of gas per treatment. PI
helps pass emissions tests. Treat gas, run that tank and fill up again prior to test.
Safe for use with catalytic converters, oxygen sensors, oxygenated gas and 10% ethanol
