Most new engines feature gasoline direct-injection(GDI) to boost power and improve fuel economy. Theseinjectors are located inside the intense heat and pressureenvironment of the combustion chamber, making themparticularly vulnerable to deposits. Extreme pressurecombined with incomplete fuel combustion can lead todramatically increased soot (particulate matter) levels.Direct injection typically creates 30 to 40 times more sootthan port fuel injectors (PFI). Even a minimal amount ofinjector fouling can lead to increased pollution and wearand decreased power and fuel economy.Injector deposits:• Decrease efficiency power and fuel economy• Increase exhaust emissions• Contribute to poor starting and rough idle
-
Fights Intake Valve DepositsValve deposits alter or restrict airflow patterns in the cylinder. They disrupt the balanced air/fuel ratio bymomentarily absorbing and releasing fuel. The depositscan also cause valve sticking by getting in the way ofthe valve stem and guide.Intake valve deposits:• Decrease power and efficiency• Increase exhaust emissions• Lead to potential valve failureP.i. helps keep valves clean and moving freely.

Combustion chamber deposits increase compression and absorb heat during combustion. Later, they release that heat during the intake cycle. In some engines deposits can cause the piston to actually hit the cylinder head – a process known as "carbon rap".The deposits can also flake off and become trapped between the valves and valve seat, resulting in compression loss.Higher compression and stored heat increase the likelihoodof pre-ignition “knock” when the fuel spontaneously combustsprior to spark ignition. This increases emissions and may causeengine damage. Most vehicles have sensors that adjust sparktiming to prevent knock. Although audible “knock” is controlled, power is lost from retarded timing and engine efficiency suffers.Higher octane fuels can be used to help prevent the phenomenon. As a vehicle ages, more-expensive, higher-octane fuel is needed to keep it operating at peak performance.Combustion chamber deposits:• Increase the possibility of “carbon rap”• Contribute to compression loss, difficult starting and rough idling• Increase the possibility of pre-ignition “knock” or “pinging”P.I. fightscombustionchamberdeposits which helps restore power, control knock, increase fuel economy and reduce the need for higher-octane fuels.

Many new vehicles have replaced traditional fuel caps with capless systems. The threads on most bottles restrict them from opening the flap inside the fuel neck and also make removing the bottle difficult.The P.i.bottle is fully compatible with capless fuel systems.
-
• For use in gasoline powered cars and trucks.• Treats up to30 gallons.Add entire bottle to tank at fill-up.• For best results, clean your fuel system with P.i. every 4,000 miles.• For large gas tanks, treat with two bottles of P.i. Using more than two bottles per treatment is not recommended.• Safe for use with catalytic converters, oxygen sensors, oxygenated gas and up to 15% ethanol blended gas.• Do not use with diesel or E85 fuel or two-stroke engines.
