Product Details

Product Description

Improves fuel mileage an average of 2.3% and up to 5.7%. Reduces emissions such as hydrocarbons (HC) up to 15%, carbon monoxide (CO) up to 26% and nitrous oxides (NOx) up to 17%. Restores power and performance. Reduces the need for costly higher octane fuel. Reduces noise from carbon rap and pre-ignition. Offers better vehicle drivability and smoother operation.

Untreated Fuel Leads to Poor Engine Performance

A vehicle demonstrates its best efficiency and engine performance when it is new. As the engine ages, its performance suffers from gasoline fuel-generated deposits that form on the fuel injectors, intake valves and combustion chamber. Additives are required to control deposit formation.

Today's fuels, however, lack sufficient treatments of either enough additives or high quality additives. Fuel system deposits result in the following:

• Lost fuel economy
• Lost power and poor throttle response
• Failed emission tests
• Poor drivability - surging, hesitation, stalling, rough idle
• Engine knocking (pinging) and rap
• Difficult starts

Treated Fuel Delivers Maximum Performance

AMSOIL P.i. is the most potent gasoline additive 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 following clean-up benefits after only one tank of gasoline:

• Improves fuel mileage an average of 2.3% and up to 5.7%
• Reduced emissions

  • hydrocarbons (HC) up to 15%
  • carbon monoxide (CO) up to 26%
  • nitrous oxides (NOx) up to 17%
• Restored power and performance
• Reduced need for costly higher octane fuel
• Reduced noise from carbon rap and pre-ignition
• Better drivability
• Smoother operation

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 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 injectors must deliver precise amounts of "atomized" fuel, even small amounts of deposits can cause injectors to malfunction. Fuel flow is reduced and spray patterns are disrupted, decreasing engine efficiency, power and fuel economy, while increasing exhaust emissions.

Intake Valve Deposits form on the intake side or back side of the valves. As deposits increase, they restrict airflow and alter airflow patterns in the cylinder. The deposits disrupt the balanced air/fuel ratio by momentarily absorbing and releasing fuel, and they can cause valve sticking by getting in the way of the valve stem and guide. Deposits also restrict proper seating, and the valves may be burned. Intake valve deposits cause lost engine power, increased emissions, poor engine efficiency and potential valve failure.

Combustion Chamber Deposits form on the top of the pistons and on the cylinder heads. They increase compression and absorb heat during combustion to later release it during the intake cycle. In some engines with tight squish domes, combustion chamber deposits cause the piston to actually hit the cylinder head. This is referred to as combustion chamber deposit interference or “carbon rap.” Combustion chamber deposits also flake off as they get large, and these flakes can get trapped between the valves and valve seat, resulting in compression loss, difficult starting and rough idle.

Higher compression and stored heat cause increased intake fresh charge temperatures and the increased likelihood of pre-ignition “knock” or “pinging” when the fuel spontaneously combusts prior to spark ignition. This increases emissions and may cause engine damage. Many of today’s cars have “knock” sensors that adjust spark timing to prevent knock.

Although audible knock is controlled, power is lost from retarded timing. Higher octane fuels of 4-5 octane numbers can be used to help prevent knock, an effect called “octane requirement increase.” As a vehicle ages, more expensive higher octane fuel is needed to keep it operating at peak performance. By cleaning combustion chamber deposits, knock is controlled, power is restored, fuel economy increases and higher octane fuels are less necessary for peak performance.

Maximum Fuel Economy
AMSOIL P.i. maximizes fuel efficiency by dissolving and removing fuel system deposits and other contaminants for improved power and overall performance.

Recommendations

Treat one full tank of gas up to 20 gallons with one bottle of P.i. For very large gas tanks, partially fill to 40 gallons and treat with two bottles of P.i. Using more than two bottles per treatment is not recommended. Treat gas every 4,000 miles or 100 hours of service. P.i. helps pass emission tests by running one tank of treated fuel through the engine prior to testing. Safe for use with catalytic converters, oxygen sensors, oxygenated gas and 10 percent ethanol blended gas. Not recommended for two-cycle engines.

DANGER: Combustible. Harmful or fatal if swallowed. Harmful if inhaled. Skin and eye irritant. Read precautions on container before use.

HEALTH & SAFETY

This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Treat your vehicle

After a long winter in storage, I toss a bottle of this into my 99 VFR800 fuel to give it that spring clean, it has not failed me yet, the bike always flashes right up and runs like a dream for the season.

HIGH QUALITY FUEL SYSTEM AND COMBUSTION CHAMBER CLEANER

I recommend AMSOIL p.I. cleaner to anyone to clean the engine combustion chamber and fuel injectors or carburetor of a gasoline engine. I've used this exact product on a recommended vehicle maintenance schedule for many years. There is a very noticeable difference to prevent engine from knocking by cleaning the carbon from the combustion chamber. I use this in a Ford truck, Pontiac car and a Kawasaki motorcycle. Highly recommended above any product of its kind is AMSOIL p.I.

I do buy this product over and over again

Before I started using this product (P.I.) my 2006 Toyota Tacome was getting about 19 - 20 MPG. When I use this product it moves easily to 20-22 MPH. It must be doing something good. However, I must admit to using exclusively Amsoil Signature oil.

Use every oil change

I use a bottle of this every time I change my oil. So far at 240,000km (145,000m) no injector problems.......

WHERES THE P.I.?

I put the product in my 2007 Chevrolet Tahoe with 140,000 miles. I did not notice a difference at all. I have used multiple Amsoil products but ill probably never use this one again.

I use this product ALL the time

I have a1970 and 1974 E Type Jaguars which were built to run on leaded 98 Octane fuel. Since researching various Octane boosting products and finding this Amsoil product I buy it by the case and use a bottle every time I fill up the tanks in my cars and they have never run better! Love this product. Improved the gas mileage as well which was an added bonus.
