AMSOIL Performance Improver Gasoline Additive
AMSOIL PI improved fuel economy by
reducing port fuel injector deposits, intake valve
deposits and combustion chamber deposits in 100% of
the vehicles tested!
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.
Todays 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 todays
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 PI maximizes fuel efficiency
by dissolving and removing fuel system deposits and
other contaminants for improved power and overall
performance.
Recommendations
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 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.
