Are you ready to take the P.i. Challenge?
First off, what is P.i.? AMSOIL Performance Improver is gasoline treatment designed to clean fuel injectors and other internal combustion components. This keeps engines running at peak efficiency for maximum performance and economy.
AMSOIL P.i. ranks among the most potent gasoline additives available today. As a concentrated detergent, it is outstanding 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:
- Improved 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
So what is the P.i. challenge?
The challenge is to try P.i. in your own vehicle. Figure out what your current fuel economy is, then test your fuel economy after a tank full of PI. You will be amazed at the difference. While the official tests show a 3-5% increase in fuel economy compared to a dirty fuel system, I have personally seen economy numbers great than 10%. This equates to a significant saving at the pump.
How to calculate your fuel economy.
- Fill your tank
- Reset the trip meter.
- Drive vehicle several hundred miles
- Refill the tank.
- Take the number of miles driven divided by the number of gallons at that fill up.
For instance, you fill your tank. Then drive 250 miles. Then you refill your tank and add 13.8 gallons of fuel. 250/13.8=18.1 miles per gallon.
You can do this over several tanks to get an average. You can also tell if you fuel mileage improves or goes down.

AMSOIL P.i. Performance Improver will save you money.
With the price of gas going over $3, we are sure to see even higher prices at the pump this summer driving season. Consumers are once again looking for ways to keep their cars running at peak efficiency. PI is just one of many ways you can save.
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, they must be kept clean. 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 most motorists are unaware of how dirty the insides of their engines are. AMSOIL P.i. Performance Improver 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, including 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.
Today there seems to be a gas station on every corner. People will drive out of there way to find the best price on gas. The problem is that the lower priced gas has even less detergents and cleaners than name brand gas does. This means it’s even more important to periodically use a fuel system cleaner like AMSOIL P.i.
AMSOIL P.i. maximizes fuel efficiency by dissolving and removing fuel system deposits and other contaminants for improved power and overall performance.
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 for marine, stationary and off-road gasoline-powered engines). P.i. helps pass emission tests (treat one full tank of gas, run that tank and fill up again prior to test). Safe for use with catalytic converters, oxygen sensors, oxygenated gas and 10% ethanol blended gas. Not recommended for two-cycle engines( see the AMSOIL Quick Shot Product).
