{"product_id":"amsoil-api","title":"Amsoil P.I. Performance Improver Petrol Additive","description":"\u003cp style=\"text-align: justify;\"\u003eAMSOIL P.i. is a potent gasoline performance improver with concentrated detergent that aggressively cleans stubborn, power-robbing deposits from injectors, valves and the combustion chamber. Effective in port and direct injection systems. Bottle compatible with capless fuel systems. Cleans entire fuel system in one tank of gasoline. For use with cars and trucks. Treats up to 30 gallons. Add entire bottle to tank at fill-up. For best results, clean your fuel system with P.i. every 4,000 miles (6,400 km). Do not use with diesel, E85 or 2-stroke mixed fuel.\u003c\/p\u003e\u003ch4 style=\"text-align: justify;\"\u003e\u003cstrong\u003eMaximum Deposit Clean-up\u003c\/strong\u003e\u003c\/h4\u003e\u003cp style=\"text-align: justify;\"\u003eAMSOIL P.i. features aggressive additives that attack the most common forms of engine deposits and limit their effects.\u003c\/p\u003e\u003ch4 style=\"text-align: justify;\"\u003e\u003cstrong\u003eRemoves Fuel Injector Deposits\u003c\/strong\u003e\u003c\/h4\u003e\u003cp style=\"text-align: justify;\"\u003eMost 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.\u003c\/p\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eInjector deposits\u003c\/strong\u003e:\u003c\/p\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli style=\"text-align: justify;\"\u003eDecrease efficiency, power and fuel economy\u003c\/li\u003e\n\u003cli style=\"text-align: justify;\"\u003eIncrease exhaust emissions\u003c\/li\u003e\n\u003cli style=\"text-align: justify;\"\u003eContribute to poor starting and rough idle\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003eP.i. removes stubborn deposits and keeps injectors functioning as they should.

Prior to testing, the truck was run on a chassis dyno and measured for HP. The 5.3L GDI engine was then disassembled, photographed and reassembled. Following a single tank of of fuel treated with P.i. driving at highway speeds, the truck was again strapped to the dyno. It measured an incredible 14% improvement in horsepower. The engine was then disassembled once again to see the impact P.i. had on deposits. The images to the right demonstrate the powerful cleaning performance of P.i on injectors and cylinder heads to significantly restore power and efficiency.\u003c\/p\u003e\u003ch4 style=\"text-align: justify;\"\u003e\u003cstrong\u003eFights Intake Valve Deposits\u003c\/strong\u003e\u003c\/h4\u003e\u003cp style=\"text-align: justify;\"\u003eValve deposits alter or restrict airflow patterns in the cylinder.

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.\u003c\/p\u003e\u003cp style=\"text-align: justify;\"\u003eHigher compression and stored heat increase the likelihood of pre-ignition “knock” when the fuel spontaneously combusts prior to spark ignition. This increases emissions and may cause engine damage. Most vehicles have sensors that adjust spark timing 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 \u003cbr\u003ephenomenon. As a vehicle ages, more-expensive, higher-octane fuel is needed to keep it operating at peak performance.\u003c\/p\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eCombustion chamber deposits\u003c\/strong\u003e:\u003c\/p\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003eIncrease the possibility of “carbon rap”\u003c\/li\u003e\n\u003cli\u003eContribute to compression loss, difficult starting and rough idling\u003c\/li\u003e\n\u003cli\u003eIncrease the possibility of pre-ignition “knock” or “pinging”\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003eP.i. fights combustion chamber deposits which helps restore power, control knock, increase fuel economy and reduce the need for higher-octane fuels.\u003c\/p\u003e\u003ch4 style=\"text-align: justify;\"\u003e\u003cstrong\u003eCapless-Compatible Packaging\u003c\/strong\u003e\u003c\/h4\u003e\u003cp style=\"text-align: justify;\"\u003eMany new vehicles have replaced traditional fuel caps with capless systems.
