The easiest defence against phase separation is to keep the tank almost full at all times, allowing a little space for the fuel to expand in warmer weather. Moisture comes from the empty space in the tank so reducing the amount of air in your tank will reduce the amount of water that can enter with the air. Ethanol may contribute to corrosion of fuel tanks and other fuel system components at a rapid rate. It is very important to pour in a fuel additive that guards against corrosion every time you fill the tank; this is especially true with small engines since many still use aluminium parts which corrode more quickly resulting in oxides that look like white rust.
A third issue is that ethanol can loosen debris that normally collects in the corners of the fuel tank and can lead to clogged fuel systems.
Again, adding a fuel treatment that contains cleaners will allow for these dirt particles to pass through your system.
That is, it loses its volatility over time and may turn to varnish. The good news is that E has been used in many parts of the country for over 25 years so there are proven ways to protect your engines from the potential hazards we have reviewed. These formulations contain a chemical that absorb water which help prevent phase separation. They use a non-alcohol water remover that bonds with water molecules, thereby allowing excess water to pass through the engine and out the tailpipe without causing damage.
However, please note that large amounts of water in a fuel tank can result in lower power acceleration, if not engine damage and failure. If too much water is present in the fuel tank, the tank will have to be drained and replaced with fresh fuel and additive. Bevill, K. Department of Agricultural and Biosystems Engineering.

This includes eye and skin contact. Alcohol, when consumed within a beverage, can also lead to alcohol poisoning, coma and death if too much is ingested. In such cases, medical attention should also be sought immediately. Depending on its usage, ethanol can be beneficial if used properly. When added to fuel, such as gasoline, ethanol helps reduce carbon dioxide emissions by 34 percent, according to the Renewable Fuels Association. By , 9 million vehicles powered by gasoline were on the road, and service stations selling gasoline were opening around the country.
Today, gasoline is the fuel for nearly all light-duty vehicles in the United States. By the s, cars were becoming bigger and faster. Gasoline octane increased, and lead was added to improve engine performance. Unleaded gasoline was introduced in the s when health problems from lead became apparent. In the United States, leaded gasoline for use in on-road vehicles was completely phased out as of January 1, Most other countries have also stopped using leaded gasoline in vehicles.
Retail gasoline is now usually sold in three grades of gasoline. In , the U. Congress enacted a Renewable Fuel Standard RFS that set minimum requirements for the use of renewable fuels, including ethanol , in motor fuels.
In , the RFS targets were set to rise steadily to 36 billion gallons by In , about Gasoline explained History of gasoline.
