Fuel additive returns your vehicle to like new drive-ability.

Of all fuel system cleaners AMSOIL P.i. is easiest and most p otent on market.  Affordable.  You treat one tank of gas.  You’re done.  Lasts 4,000 miles.

UNSURPASSED DEPOSIT CLEANUP

Benefits of P.i. Gasoline Additive

• Cleans combustion chambers.

• Cleans back of plates, idle air passages, fuel portals.

• Cleans fuel injectors.

• Increases fuel economy.

Testing yielded improvement of up to 5.7 percent

Keep it clean with a fuel system cleaner that is effective and safe for your vehicle's engine

• Restores power, acceleration and drivability to “like new” condition.

• Reduces emissions and helps vehicles pass emission tests.

Up to 15 % reduction hydrocarbon emissions.

Up to 26 % reduction carbon monoxide emissions.

Up to 17 % reduction nitrous oxide emissions.

• Avoids necessity of your mechanic’s fuel system cleaner service which can be quite expensive.

• Reduces engine octane requirement, saving money at the pump.

Gasoline Additive Concentrate,

P.i. Delivers Maximum Performance

AMSOIL P.i. is the most potent of fuel injection cleaners available today. As a concentrated detergent, it is unsurpassed in cleaning combustion chamber deposits, intake valve deposits and port fuel injector deposits.  AMSOIL P.i. helps maintain peak engine efficiency, fuel economy, power and drivability in newer low mileage engines.  In engines with accumulated deposits, testing showed AMSOIL P.i. provided the above listed clean-up benefits after only one tank of gasoline:

Carburetor plates are cleaned by P.i. just as effectively as modern vehicle fuel injectors, intake valves and combustion chambers. The back sides of the plates, the idle air passages and all the fuel portals are cleaned just as it cleans all the components in a fuel injection system.

AMSOIL P.i. works as an “emissions passer.”

It is ideal for use prior to emissions inspections.

Unsurpassed Deposit Clean-up

Port Fuel Injector Deposits form after the engine has been shut down and there is no gasoline flowing through the fuel injectors.

During this “hot soak” period the injectors heat up and the gasoline remaining in the injectors degrades and forms deposits.

This can happen very quickly with the use of poor quality gasoline and short trip driving.  Because the clearances within the injectors are extremely tight and fuel injectors must deliver precise amounts of “atomized” fuel, even small amounts of deposits can cause injectors to malfunction.  Fuel system flow is reduced and spray patterns are disrupted, decreasing engine efficiency, power and fuel economy, while increasing exhaust emissions.

Above you see the combustion chamber before and after P.i. fuel system cleaner. When combustion chamber deposits are removed then the secondary ignition source, the deposit interference and the flaking no longer negatively affect the combustion / spark plug process.

Smaller Engines Can Be More Sensitive to Deposits.

In tests, although the Honda and two Toyota vehicles had the lowest levels of deposits prior to P.i. treatment, they experienced the largest fuel economy increases after treatment, indicating that even minimal levels of deposits can have significant effects on fuel economy.  In fact, many smaller engines designed for maximum fuel efficiency are among the most sensitive to deposits.

Why Vehicles Need A Fuel System Cleaner

In response to Environmental Protection Agency (EPA) fuel economy and emissions regulations, fuel injection systems replaced carburetors in new vehicles in the 1980s.  Fuel injectors provide drivers with more precise control of fuel, improving fuel efficiency and minimizing emissions.  However, in order to work efficiently, cleaning fuel injectors is necessary.

Because performance suffers as fuel injectors become dirty, the U.S. government mandated in the mid-1990s that all gasoline sold in the U.S. be formulated with a lowest additive concentration (LAC) level of detergent additives to help keep engines clean and emissions under control.  However, it takes a very low level of additive to pass the tests, and most gasoline on the market contains as little as 123 parts per million (ppm) of additive.

The low levels of detergent additives in modern gasoline allow deposits to build up on critical fuel system components and fuel injectors.  Most motorists are unaware of how dirty the insides of their engines are.

AMSOIL P.i. is an effective one tank, total fuel system cleaner. More potent than other fuel additives on the market, P.i. effectively cleans everything the fuel touches, cleaning fuel injectors, intake valves and

combustion chambers, in only one single tank of gasoline, removing the deposits that have built up over thousands of miles.  Removing engine deposits with P.i. effectively improves fuel economy, reduces emissions, restores power, performance and acceleration, reduces octane requirements, increases engine life and reduces maintenance costs.

Fuel System Cleaner Recommendations

Treat one full tank of gas up to 20 gallons with one bottle or up to 40 gallons with two bottles. Using more than two bottles per treatment is not recommended.  Large gas tanks should only be partially filled to 40 gallons to maintain the proper concentration ratio of one bottle per every 20 gallons for best results.  Treat every 4,000 miles or 100 hours of service.

MORE DETAIL::::

P.i. helps pass emission tests (treat one full tank of gas, run that tank and fill up again prior to test).

P.i. is safe for use with catalytic converters, oxygen sensors, oxygenated gas and 10% ethanol blended gas.

Not recommended for two-cycle engines.

AMSOIL also has QUICKSHOT for small engines, motorcycles.

Images of spray are before and after cleaning fuel injectors. These are patterns for port fuel injectors which are standard equipment in modern vehicles. This image is before cleaner. After tests with the fuel system cleaner Amsoil P.i., all fuel injectors returned to greater than 95% flow.

When clean, they provide the exact amount of gasoline the engine needs, transferring liquid gasoline from the tank to spray in a fine mist into the intake air stream. Precision is key. After tests with the fuel system cleaner Amsoil P.i., all fuel injectors returned to greater than 95% flow.
