MAXIMUM DEPOSIT CLEAN-UP

• Helps keep valves clean and moving freely.
• Aggressive additives attack the most common forms of engine deposits and limit their effects.

REMOVES FUEL-INJECTOR DEPOSITS

• P.i. removes deposits and keeps injectors functioning as they should.
• Testing shows P.i. restored GDI fuel injectors to a 100% flow rate after one tank of fuel.²

RESTORES HORSEPOWER

• Third-party testing demonstrated performance of P.i. using a 2016 Chevrolet* Silverado* with 100,616 miles on the odometer.
• Following a single treatment with P.i., the truck measured an incredible 14% improvement in horsepower.¹

CLEANS COMBUSTION CHAMBER DEPOSITS

• Fights combustion chamber deposits to help restore power, control knock, increase fuel economy and reduce the need for higher-octane fuels.
• Protects against compression loss, difficulty starting and rough idling.
• Reduces possibility of "carbon rap," when deposit buildup causes the piston to hit the cylinder head.
• Decreases the possibility of pre-ignition "knock" or "pinging."

CAPLESS-COMPATIBLE BOTTLE

• Bottle is fully compatible with capless fuel systems.
