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.

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.
