The numbers of automobiles and non-road engines that can be affected by ethanol blended gasoline is significant. According to studies cited by The Environmental Working Group, there are 247 million cars, trucks and buses and 400 million non-vehicle gasoline engines. Many of these have the potential of severe fuel system damage.
“The limited data available clearly indicate that non-road engines and a sizable number of older, still roadworthy vehicles could be damaged by increased levels of ethanol in fuel,” reports Olga V. Naidenko, PhD, Senior Scientist, Environmental Working Group.
In order to combat the harmful effects of Ethanol, Eastwood has created the new Fuel Guard™ additives. Eastwood’s Fuel Guard helps prevent corrosion in fuel systems and internal engine components, gum and resin build-up, clogged carburetors, injectors, filters and fuel lines, deterioration of certain types of rubber used in seals and hoses, plus aggravation of water and moisture problems in fuel storage or unused engine situations.
“Ethanol blended in gasoline actually attracts water. This causes the water and gasoline to separate, producing Phase Separation. Phase Separation can create severe fuel system damage. Once it has taken place, it presently cannot be reversed,” Robinson warned.
Eastwood’s Fuel Guard ™ Daily Driver formula is engineered for use with every fill-up or up to 30 gallons of fuel, and is intended for use in frequently driven vehicles. Eastwood’s Fuel Guard™ Storage Formula preserves fuel for up to 12 months, and is recommended when preparing a vehicle for storage. Both formulas prevent Ethanol Phase Separation, corrosion in the fuel system and engine components, protects against gum and resin build-up, and prevents clogged carburetors, injectors, filters and fuel lines.
Eastwood’s Fuel Guard™ is compatible with all two and four stroke engines and contains no harmful alcohol or hydroscopic additives.
Lawn mowers, chain saws and marine engines are examples of 2-stroke engines. In these cases, the moisture caused by Phase Separation, will compete with the blended oil for bonding to metal engine parts. The engine will be robbed of lubrication and severe damage could occur. Additionally, rubber and plastic fuel system components can be permanently damaged. Many small engines use plastic fuel tanks, which are prone to deterioration caused by Ethanol Phase Separation.
While most late model vehicles have been designed to be compatible with ethanol-blended gasoline, there is up to a 3% loss in fuel economy from the use of E10 gasoline because it has less energy content according to the Maine Department of Environmental Protection (DEP Fact Sheet, December 19, 2008).
Eastwood markets unique tools and supplies for repair, restoration, and modification of cars, trucks, and motorcycles.
