P.i. Performance Improver Concentrate AMSOIL P.i. 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 effi ciency and engine performance 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 suffi cient treatments of either enough additives or highquality 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 • Diffi cult starts Treated Fuel Delivers Maximum Performance AMSOIL P.i. ranks among the most potent gasoline additives available today. As a concentrated detergent, it is outstanding in cleaning combustion chamber deposits, intake valve deposits and port fuel injector deposits. AMSOIL P.i. helps maintain peak engine effi ciency, 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 benefi 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 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.
