WHY SHOULD I WORRY ABOUT ETHANOL?
Ethanol is in almost all the gasoline you buy, with levels as high as 20% in parts of the country. Although the idea was to use ethanol to reduce America's dependence on foreign oil and provide a much needed economical boost to American farmers. American families are finding out that ethanol is not that friendly when it comes to the fuel systems in their vehicles, boats, motorcycles, snowmobiles, power equipment, lawnmowers and other gasoline powered 2 or 4 stroke engines. Many people are not even aware of the corrosive damage ethanol is causing or how to eliminate it.
Ethanol is Corrosive!
Ethanol, like all alcohol, is very corrosive and hygroscopic (attracts and absorbs water from the air and it's surrounding), which is not a good combination for boats or personal watercraft. High amounts of this extremely corrosive mixture, of water and ethanol, will corrode all fuel system components not designed for it. Besides the corrosive nature of this mixture, the increase in water will begin to rust out the top of gas tanks this includes in warm weather climates that normally do not have an issue with rust.
Ethanol Damages Fuel Systems!
Ethanol's ability to attract and absorb liquids means that it prevents the natural lubricants in gasoline from doing their job, causing all non-alcohol resistant parts like rubber and plastic to dry out, crack and eventually fail. High levels of oxygen in ethanol blended fuels cause fuel to decay much faster and if left to sit, that decay leaves deposits such as varnish and sludge. The deposits left by the decaying ethanol blended fuel will clog fuel filters, fuel injectors, carburetors and fuel lines. Making your engine hard to start, idle rough, stall and in extreme circumstances engine failure.
Ethanol Decreases Fuel Mileage!
High levels of oxygen in ethanol causes fuel to burn much faster than fuel without ethanol. Which means more fuel is needed to produce the same amount of power. Although ethanol blended fuels will generate more horsepower. They do so at a cost, that cost is seen at the pump with lower miles per gallon.
Ethanol Decreases Fuel Life!
Ethanol increases the octane level in your fuel, because of this the base gasoline that is used to mix E10 or E20 starts off at a lower octane level. Ethanol blended fuels will begin to decay in as little as 2 months due to ethanol evaporating at a much faster rate than gasoline, leaving behind the much lower octane base stock. This is a serious problem for boats, lawnmowers and all other forms of power equipment that do not get used as frequently as your car. The majority of small engines today are not built or designed for ethanol and have much smaller fuel system components. These smaller components are much more susceptible to ethanol damage at a much faster rate.
