Product Overview
Maximum Deposit Clean-Up
AMSOIL P.i. features aggressive additives that attack the most common forms of engine deposits and limit their effects.
Removes Fuel Injector Deposits
Most new engines feature gasoline direct-injection (GDI) to boost power and improve fuel economy. These injectors are located inside the intense heat and pressure environment of the combustion chamber, making them particularly vulnerable to deposits. Extreme pressure combined with incomplete fuel combustion can lead to dramatically increased soot (particulate matter) levels. Direct injection typically creates 30 to 40 times more soot than port fuel injectors (PFI). Even a minimal amount of injector fouling can lead to increased pollution and wear and decreased power and fuel economy.
Injector deposits:
- Decrease efficiency, power and fuel economy
- Increase exhaust emissions
- Contribute to poor starting and rough idle
P.i. removes stubborn deposits and keeps injectors functioning as they should. Testing shows P.i. restored GDI fuel injectors to a 100 percent flow rate after one tank of fuel.2
Fights Intake Valve Deposits
Valve deposits alter or restrict airflow patterns in the cylinder. They disrupt the balanced air/fuel ratio by momentarily absorbing and releasing fuel. The deposits can also cause valve sticking by getting in the way of the valve stem and guide.
Intake valve deposits:
- Decrease power and efficiency
- Increase exhaust emissions
- Lead to potential valve failure
P.i. helps keep valves clean and moving freely.
- Restores power and performance
- Reduces need for costly higher-octane fuel
- Reduces noise from carbon rap and pre-ignition
- Controls pre-ignition "knock"
- Improves fuel economy
- Capless compatible
