AMSOIL P.i. improved fuel economy by reducing fuel injector deposits, intake valve deposits and combustion chamber deposits in 100% of the vehicles tested. It is formulated for both gasoline direct injected (GDI) and
port fuel injected engines.
Maximum Deposit Clean-up
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. Being located in the combustion chamber, GDI injectors are also subjected to intense heat and pres- sure, making them even more suscep- tible to deposits. Even small amounts of deposits can cause injectors to malfunc- tion. Fuel ow is reduced and spray pat- terns are disrupted, decreasing engine ef ciency, power and fuel economy, while increasing exhaust emissions.
Untreated Fuel Leads to Poor Engine Performance
A vehicle demonstrates its best ef ciency and engine perfor- mance when it is new. As the engine ages, its performance suffers from gasoline-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 suf cient 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
• Dif cult starts
Treated Fuel Delivers Maximum Performance
AMSOIL P.i. ranks among the most potent gasoline additives. As a concentrated detergent, it is highly effective in cleaning combustion chamber deposits, intake valve deposits, port fuel injector deposits and gasoline direct injector deposits. AMSOIL P.i. helps maintain peak engine ef ciency, fuel economy, power and drivability in newer low-mileage engines. In engines with accumulated deposits, testing shows AMSOIL P.i. provided the following clean-up bene ts after only one tank of gasoline:
• Improved 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 GDI injector ow to 99.1%
• 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.
Maximum Fuel Economy
AMSOIL P.i. maximizes fuel ef ciency 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 ll to 40 gallons and treat with two bottles of P.i. Using more than two bottles per treatment is not rec- ommended. Treat gas every 4,000 miles of service (or 100 hours for marine, stationary and off-road gasoline-powered engines).
P.i. helps pass emission tests by running one tank of treated fuel through the engine prior to testing. Safe for use with catalytic con- verters, oxygen sensors, oxygenated gas and 10 percent ethanol blended gas. Not recommended for two-cycle engines.
