AMSOIL Performance Improver will increase your mileage. Guaranteed, or your money back!
Your vehicle is at its best performance when it is new. As your drive, deposits form on fuel injectors, intake valves and combustion chamber. Additives are required to control deposit formation.
Fuel producers naturally only add the federally mandated additives. These federal mandates have not been updated since the '80s. So the fuel you add to your vehicle does not have the additives required to maintian your fuel system.
Fuel system deposits result in poor fuel economy, poor performance, higher emissions, rough engine idle, pinging, and difficult starting.
P.i. Money-Back Guarantee
The high price of fuel is a major concern for people and businesses. As prices continue to reach record-setting levels, fuel economy has become increasingly important for customers everywhere, and people are doing everything they can to stretch their fuel dollars. AMSOIL P.I. Gasoline additive can help. It increases fuel economy, reduces emissions and restores vehicle performance by dissolving and removing combustion chamber, intake valve and fuel injector deposits. Field testing shows AMSOIL P.I. provides an average fuel economy improvement of 2.3 percent and up to 5.7 percent.
AMSOIL P.I. Performance Improver is so effective the company now offers a money-back guarantee on the product's fuel economy benefits. If the customer does not see fuel economy improvement in his or her vehicle after a first-time use of P.I., AMSOIL will refund the purchase price of the product.
If the customer does not see fuel economy improvement in his or her vehicle after a first-time use of P.I., AMSOIL will refund the purchase price of the product.
P.i. Money-Back Guarantee Conditions
The money-back guarantee is good through May 31, 2009 and is open to everyone (including AMSOIL Dealers, Preferred Customers, retail customers, catalog customers, commercial and retail accounts). The P.i. money-back guarantee is limited to vehicles with a minimum of 25,000 miles that have not previously been treated with P.i. and have not undergone any fuel system or fuel injector cleaning procedure. P.i. must be used with a full tank of gas, and the P.i. treated gas must be run until the tank is near-empty before filling up again. Fuel economy measurement will then be taken on the tankful of gas following the P.i.-treated tank.
Customers are eligible for the refund if they do not see a fuel economy improvement following use of the subsequent tank of gas after P.i. treatment. If a customer had not received a fuel economy benefit and wishes to take advantage of the money-back guarantee, he or she may simply download and print the rebate form. (P.i. Rebate form ). The form contains complete qualification details and must be completely filled out and mailed with the P.i. purchase. Individual refunds are limited to the suggested retail price listed by AMSOIL INC. for P.i. Performance Improver.
Treated Fuel Delivers Maximum Performance
AMSOIL P.i. is the most potent gasoline additive available today.
AMSOIL P.i. is the most potent gasoline additive available today.
• 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.
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.
