How To Maintain Your Engine With AMSOIL Synthetic Additives

We would all like to get better gas mileage, create fewer emissions and obtain our vehicles' optimal performance. That's why the pros use AMSOIL Gasoline and Diesel Fuel Additives to restore performance and reduce the need for costly high octane fuels. AMSOIL Synthetic Oil and Lubricants have an outstanding history as THE FIRST IN SYNTHETICS, and it's that superior formulation and standard we need now more than ever.

Ethanol at the Pump
Ethanol in our gasoline is causing corrosion in today's engine. To combat that fuel additives are needed now more than even. AMSOIL Quickshot is just what your motorcycle requires to restore performance and keep the engine clean and running strong.

Engine Corrosion

To understand how this engine corrosion happens, you need to know how ethanol affects your fuel system. Ethanol itself is not particularly corrosive. When the oil companies first started blending ethanol in gas, it corroded some rubber and plastic gaskets on some cars and equipment. Manufacturers figured it out and substituted new materials. But that's not the end of it. Ethanol attracts water. When the two get together, they create the perfect environment to grow a type of bacteria called acetobacter. Acetic acid is very corrosive. If you’re refilling your gas tank every week or two, acetobacter doesn’t have time to grow a sufficient size colony to damage metal parts in your fuel system. But if your fuel sits for longer periods of time these microorganisms continue to multiply until your gas tank contains damaging levels of acetic acid. How to beat the sitting sludge? AMSOIL Gasoline Stabilizer reduces the oxidation process that occurs when fuel is stored for extended periods.

When Ethanol Levels Increase Performance Decreases

Acetobacter excretes acetic acid. And acetic acid is very corrosive. Ethanol is also now starting to show up in diesel fuel. This isn't good for today's fuel sensitive, high-pressure diesel fuel injection systems. The source of this diesel contamination is unclear, but it is widespread. Given enough time and the right conditions, ethanol will do just as much damage to diesel fuel and storage systems as it does to gasoline engines and equipment. Time to pick up AMSOIL Diesel Injector Clean. It gets to work removing performance robbing deposits in diesel engines.

How Much Ethanol is in Gasoline

In 2014, about 13 billion gallons of fuel ethanol were added to the motor gasoline produced in the United States. Fuel ethanol accounted for about 10% of the total volume of finished motor gasoline consumed.

Most of the gasoline now sold in the United States contains some ethanol, but the exact amount varies by region. In general, the ethanol content of motor gasoline does not exceed 10% by volume. Gasoline with 10% ethanol content is referred to as E10, and gasoline with 15% ethanol content is called E15. E85 is a fuel that averages 85% ethanol and 15% gasoline. Most of the motor gasoline with more than 10% ethanol is sold in the Midwest.

All gasoline vehicles can use E10. Currently, only light-duty vehicles with the model year 2001 or greater can use E15. Only flex-fuel vehicles can use gasoline with an ethanol content greater than E15.

The energy content of ethanol is about 33% less than pure gasoline, although this varies depending on the amount of denaturant that is added to the ethanol. Therefore, vehicle fuel economy may decrease by up to 3.3% when using E10.

Ethanol is an Engine Killer

It is accepted in the engine industry that Ethanol is bad, but what does bad mean? Gearheads have long heard of the issues related to Ethanol blended fuels. Their solution is AMSOIL DOMINATOR® Octane Boost. It quickly maximizes power and improves performance in all two-cycle and four-cycle gasoline engines by increasing octane up to 4 numbers. It also reduces engine knock, improves ignition and engine response. It even helps fuel burn cleaner and inhibits corrosion.

Ethanol and Water Mix

Ethanol is hygroscopic. It means that Ethanol likes water. The problem with this is that water makes an awful fuel source. During periods of extended storage, Ethanol tends to draw in atmospheric moisture that can lead to a build-up of water in your fuel cell or container. Because the density of water is greater than gasoline, the Ethanol/Water mixture separates from the gasoline and settles to the bottom of the fuel cell. The Automotive Industry refers to this as Phase Separation, and because the pick-up is located on the bottom of the fuel cell, the first thing sucked up when you try to crank the engine is the Ethanol/Water mixture.

Not only will this cause your lawnmower not to start. It will also pump a corrosive cocktail through your engine, and since some of that water/Ethanol cocktail ends up in your crankcase, your motor oil is not very happy or healthy either.

Carburetor Corrosion

Many people do not realize that Ethanol is not transported in the pipelines with gasoline. The ethanol is added later just prior to delivery to your local gas station. You see, ethanol is very corrosive, so the pipeline companies don’t want the Ethanol eating their pipelines. While modern fuel injection engines feature materials compatible with Ethanol, Carburetors are made from alloys of Zinc and Aluminum, both of which are susceptible to corrosive properties of Ethanol. Many carburetor rebuilders have reported seeing “white” deposits inside the Carburetors, and detailed laboratory analysis confirmed that these deposits are the result of corrosion from Ethanol blended fuels. The greater the ethanol concentration, the worse the problem, and periods of extended storage only worsen the problem. In fact, the US Department of Energy’s Oak Ridge National Laboratory warns against the use of Zinc or Aluminum with Ethanol. Additives designed to help prevent Phase Separation contain Alcohol that can make the corrosion problem worse.

The water that accompanies the ethanol just adds to the corrosion problem. The moisture that passes through the fuel system and ends up in the crankcase can lead to rust inside the engine, and water depletes to additives in your motor oil that are designed to prevent rust and wear. Think less performance, reliability and vehicle lifespan. Ethanol is an alcohol; ethanol dries out the rubber components in your fuel system. This leads to cracking and brittle fuel lines, floats, seals and diaphragms. Obviously, leaky fuel lines are costly and a safety hazard.

These material compatibility issues are even worse for small engines. The Carburetors on a typical small engine, like your two-stroke leaf blower, use a diaphragm style fuel pump. The ethanol in the fuel causes the diaphragm to harden. The fuel pump stops working, and now your leaf blower won’t run.

The fuel lines, fuel cell, and other rubberized components must be replaced with materials that are compatible with high ethanol content fuels. All modern (since 2007) cars feature these upgraded materials that are compatible with Ethanol blended fuels (this is one of the special parts in a flex fuel vehicle).

Prevent Ethanol Destruction

The best way to prevent phase separation is not always to add another bottle of fuel stabilizer into your tank. An AMSOIL Synthetic fuel additive with a corrosion inhibitor for your carburetor is what you (and your engines) need. The best way to prevent phase separation is by making sure the fuel cell is full when you put your vehicle, lawnmower or boat away in storage. With less room to breathe the fuel cell will not absorb enough moisture to cause phase separation. If the fuel cell can’t be stored full, then run it dry before putting it away for storage. The fastest route to phase separation is a partially full tank of ethanol blended fuel allowed to breathe in atmospheric moisture.

Vapor Pressure

Ethanol affects the nature of how gasoline evaporates, and that changes how the fuel system must be tuned. Because the ethanol content in pump fuels varies, the effect on vapor pressure varies, which means the performance qualities of the fuel varies from tank to tank.

Obviously, the best course of action is to use Ethanol free fuel. However, as we know, these fuels are hard to find due to clean air regulations. Not to mention, these fuels cost more. Fortunately, the worst side effects of ethanol can be dealt with by using the right AMSOIL Synthetic Oil and lubricants, specifically AMSOIL Fuel Additives for Gasoline or Diesel Engines. With the correct materials in the fuel system, taking care to use a corrosion inhibitor additive if you have a carburetor, and making sure the tank is full when you put away your vehicle, lawnmower or boat, the devastating effects of ethanol in your engine will be significantly reduced.

Can You Just Not Use Gasoline with Ethanol?

In 2003, nobody thought that E-10 would dominate 99 percent of the gas supply in the U.S. In Springfield, finding high octane, clean, ethanol free fuel is expensive and difficult. It's nearly impossible if traveling along an interstate. An AMSOIL fuel additive like P.i. Improver Gasoline Additive is a more convenient and cost-effective measure.

AMSOIL Additives for all Your Motor Needs

Ethanol corrosion isn't just affecting our cars and motorcycles. This  kind of corrosion is occurring here in Chambersburg, PA and all across the country to people who store their chainsaws, string trimmers, lawn mowers, motorcycles, and ATVs without ethanol-fighting gas stabilizers. Remember to use an AMSOIL Synthetic Fuel Additive in every motor you own.
