Ethanol is a powerful solvent and when first introduced, it strips away any gums, varnish, or other build-up found in fuel tanks and fuel delivery systems. This debris drops into the fuel and leads to clogged filters, injectors and carburetors. A good enzyme breaks down this debris into sub-micron sized particles that are safely burned away while the engine operates. This greatly reduces the engine problems associated with the initial use of E10 fuels.

Ethanol attracts moisture from the atmosphere, chemically bonding with it to form an ethanol/water molecule. Water in the fuel causes engines to run rough, stall and can lead to internal damage to engine components. Fuel will naturally hold .05% water in suspension. When water levels exceed this threshold, the water drops out of suspension. The water/ethanol molecules are heavier than the fuel and drop to the bottom of the tank. This is phase separation.

Ethanol provides a significant amount of the fuel’s octane, so when the ethanol separates and drops to the bottom of the tank, the remaining fuel is left without enough octane to properly operate the engine. Plus, the ethanol/water mixture is only partially combustible which can lead to severe engine problems.

Adding enzymes prevent the water and ethanol molecules from chemically bonding. Therefore, the water falls harmlessly to the bottom of the tank, leaving the ethanol molecules in suspension with the fuel and preserving the fuel’s octane rating. This prevents phase separation from occurring. The remaining water on the bottom of the tank is broken down to sub-micron size allowing it to be safely burned away while the engine is operating.

Ethanol and gasoline do not chemically bond; instead, they are held together in a weak suspension. Over a short period of time, the E10 fuel begins to break down. The fuel begins forming solids which can clog the fuel delivery system and reduce octane ratings. Use a powerful fuel stabilizer to prevent the fuel’s breakdown and rejuvenate old fuel, restoring it to serviceable condition.

Ethanol does not produce as much energy as gasoline, losing up to 20+% of its power. E10 fuels result in decreased performance, reduced throttle response and greatly reduced fuel economy. Unburned fuel leads to carbon deposits. Adding enzymes allow more oxygen to attach to the fuel molecules at the time of combustion, resulting in a more complete burn of the fuel. This leads to greatly improved fuel economy as well as restored power and throttle response. The enzymes remove existing carbon deposits and future deposits are prevented.

Engines can run on a mixture of 10% ethanol and 90% gasoline. Adding more alcohol will cause the fuel to no longer comply with the engine manufacturer’s requirements and can lead to engine damage and voided warranties. Many fuel additives contain alcohol. Read the product MSDS before you add it to your fuel. To avoid major problems, know what you are adding to your fuel!
