DEEP CLEAN: P.I. GASOLINE ADDITIVE – More Miles Instantly

Written by Charleen

Deep Clean:

P.I. PERFORMANCE IMPROVER GASOLINE ADDITIVE

P.i. Performance Improver Gasoline Additive (API) now features a new label, formula and capless- compatible bottle. The popular deep-cleaning gasoline additive continues to restore your engine’s power and performance and increase fuel economy.

Maximum Fuel Economy

AMSOIL P.i. (Performance Improver)  is a potent gasoline performance improver featuring concentrated detergents that aggressively clean stubborn, power-robbing deposits from injectors, valves and combustion chambers. It reduces emissions and increases fuel economy up to 5.7 percent. P.i. cleans your entire fuel system in one tank of gasoline and restores engine power and performance.

It’s also our best selling non-motor oil product here in the Sioux Falls (Exit 73) store. Also find it at Stan Houston’s

AMSOIL did their research and worked with the additive suppliers to create this product – thus don’t waste your time with other on the shelf “injector cleaner(s)”. If you have that’s great too as you will have something to compare results.

Deposit Clean-up

GDI injectors are located inside the intense heat and pressure environment of the combustion chamber, making them particularly vulnerable to deposits. Even small amounts of deposits can lead to decreased power and fuel economy. P.i. features improved cleaning power to remove stubborn deposits and keep GDI injectors functioning as they should.

Going Capless

Many new vehicles have replaced traditional fuel caps with capless systems. While adding some convenience at the gas pump, the feature can make using fuel additive bottles a challenge. The threads on most bottles are easily hung up and make treating fuel and removing the bottle difficult. The new P.i. bottle is fully compatible with capless fuel systems.

Formulation Change? Yes. The basic P.i. formula and benefits are the same, but we’ve added to them with new chemistry to better target deposits in direct-injection engines.

New Stock Number? No

New Treat Rate? Yes. Treats up to 30 gallons. Add entire bottle to tank at fill-up.

Pricing Change? No

  • Restores power and performance
  • Reduces need for costly higher-octane fuel
  • Reduces noise from carbon rap and pre-ignition
  • Controls pre-ignition “knock”
  • Maintains the engine efficiency, fuel economy and power of new vehicles
  • Capless compatible

Knocking Out Pre-Ignition

Most 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 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 and costly higher octane fuel is no longer necessary.

Why Jay Leno Is Angry About Ethanol In Gasoline

Ed Newman|

Change is the one constant in life. It’s also difficult, because when there is a change – whether in technology or how we do things – there are often unforeseen consequences.  One of the changes that has been taking place is that since 2005, the U.S. government has mandated that gasoline contain ethanol, most of it derived from corn.  The aim of this policy, among other things, has purportedly been to reduce our nation’s dependence on foreign oil, though it may also be a way to utilize the excess corn of our megafarm corn growers. What this change has done is to set in motion a number of unintended consequences, from its impact on food prices to mechanical issues in our cars and other equipment with engines.

And this latter is what prompted comedian and car collector Jay Leno to write a somewhat impassioned column in Autoweek this month titled, “Can’t We Just Get Rid Of Ethanol?”

Leno argues that this change to ethanol in gasoline has damaging consequences for older cars. The piece begins with a paragraph about the rise in the number of old-car fires lately, stating that the cause is related to the corrosive nature of ethanol when in contact with fuel-pump diaphragms or old rubber hose lines.

Change is a challenge in any field of endeavor, which is why we depend on others to help make us aware of the consequences of change so that worst case scenarios can be avoided. When fuel injectors became the standard in modern engines it was soon learned that deposits on the injector tips needed to be managed. AMSOIL introduced P.i Performance Improver at that time to address this, a much cheaper solution than replacing injectors every time they fouled.

So it is that ethanol in gasoline is now recognized to be a serious issue due to a phenomenon called phase separation. Ethanol is susceptible to water intrusion; when water collects in the gas tank through condensation or other means, the bond between ethanol and gasoline can break because ethanol is hygroscopic (it likes water more than it likes gasoline).

When the ethanol bonds with moisture it sinks to the bottom of the fuel tank, which can create a whole host of problems, including the formation of gums, varnish and other insoluble debris that can plug fuel flow passages and negatively affect engine performance. When this ethanol/water mixture is pulled into the engine, it creates a lean-burn situation that increases combustion chamber temperatures and can lead to engine damage.

Four years ago AMSOIL earned a SEMA New Products award for Quickshot, a gasoline additive developed specifically to address this issue of phase separation. Though initially introduced in a smaller package size for small engines, AMSOIL more recently introduced a quart-sized bottle for automobiles that sitt idle for any length of time.

The more you know, the more you discover how important it is to stay current with the changes occurring all around us, especially when it involves something you’re passionate about like your cars.

A Look at Today's Gasoline Issues and Quality

Written by Fiona

Gasoline is the source of your vehicle’s power – and many of its problems.

Gasoline quality is vital, yet often overlooked.

Gasoline’s influence on our lives can’t be overstated. Remember how the gas lines of the 1970s disrupted daily life? People waited hours to fill up – if there was any gas available once they finally pulled up to the pump. Odd-even rationing dictated that motorists could only fill up on even-numbered days if the last digit on their license plate was even. The fallout of the gas shortages of the 1970s was a driving force behind the government mandates to increase fuel efficiency that continue to influence the industry today.

A few years ago, when gas hit $5 a gallon in some places, stories populated the Internet and airwaves about people willfully losing money to sell their giant SUVs in favor of small, fuel-efficient cars. Some people even took a loss on their houses in the suburbs to move closer to work.

In many ways, gasoline makes the world go ‘round, yet many of your customers likely know almost nothing about it, including the negative effects it can have on their vehicles.

Gasoline is distilled from petroleum crude oil. Typically, a 42-gallon barrel of crude will yield about 19 U.S. gallons of gas. The final blend can contain hundreds of different ingredients, among which are detergency additives designed to prevent harmful deposits from forming inside your engine.

In 1995, the EPA introduced its minimum gasoline detergent standard, known as lowest additive concentration (LAC). The intent was to ensure that all gasoline available in the country contained sufficient detergent additives to combat formation of deposits that reduce fuel efficiency and performance.

The widespread use of electronic fuel injection in the 1980s was a driving force behind the introduction of the LAC mandate. It quickly became evident that fuel injectors were especially sensitive to deposits, and the gasoline of the time didn’t contain sufficient detergents.

Deposit formation on the injector tips disrupts the spray pattern, which reduces fuel economy and results in less-efficient combustion. This contributes to increased tailpipe emissions since unburned gasoline can escape the combustion chamber on the engine’s exhaust stroke.

Deposits can also form on the intake valve, piston crown and in the ring grooves. They can prevent the intake valve from closing completely, reducing engine compression and horsepower. Deposits in the ring grooves can lead to ring sticking, which also reduces engine compression since a stuck ring won’t seal the combustion chamber completely. Piston crown deposits act like a sponge that soaks up gasoline. This can result in preignition, where the fuel/air mixture ignites sporadically, reducing performance and potentially damaging the engine.

Many automakers today don’t think the LAC mandate goes far enough. In fact, many gasoline marketers have reduced detergent levels by up to 50 percent, according to www.toptiergas. com. TOP TIER Detergent Gasoline is a performance specification designed by several of today’s top automakers.

Today’s vehicles run even hotter than they did in 1995. Since then the number of engines that use turbochargers, which increase heat, has grown substantially. So, too, has the number of vehicles that use direct fuel injection, which locates the injectors directly in the combustion chamber, exposed to intense heat. Plus, injectors today are more highly engineered with tighter tolerances, meaning even minute deposits can interfere with performance.

Gasoline is the source of your vehicle’s power – and many of its problems if you don’t perform proper maintenance. We formulate AMSOIL P.i.® to be one of the most potent additives on the market. It contains a very high dose of fuel detergents proven to combat the problems associated with gasoline, keeping injectors clean and functioning properly. In fact, testing showed dirty injectors returned to >95 percent flow after only one tank of gas treated with P.i. Just take a look at the dramatic before/ after images above.

As vehicles become more sophisticated and sensitive to gas quality, make sure you understand the importance of maintaining them with a quality fuel additive. AMSOIL provides solutions to problems you may not even be aware of.
