Product: Amsoil P.i. Performance Improver
Brand: Amsoil
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% * Reduces emissions  --hydrocarbons (HC) up to 15% --carbon monoxide (CO) up to 26% --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  Recommendations: 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 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 converters, oxygen sensors, oxygenated gas and 10 percent ethanol blended gas. Not recommended for two-cycle engines.
