Fuel Testers - Protect your engines from ethanol alcohol blend gasolines.

View State by State Fuel Laws and Ethanol Labeling Laws.

In summary, the reason you now have alcohol blend fuels (E10) at most gas station pumps is because of the following U.S. government and EPA legislation:

The Clean Air Act (1990) and Alternative Motor Fuels Act (1988)

The Energy Policy Act (2005)

The Renewable Fuel Standard Program (RFS September 2006)

----------------------------------------------------------------------

September 7, 2006 The Renewable Fuel Standard Program (RFS) is signed. This national renewable fuel program is designed to encourage the blending of renewable fuels (ethanol) into our nation's motor vehicle fuel. The nationwide Renewable Fuels Standard (RFS), will double the use of ethanol and biodiesel by 2012.

In 2006 production of ethanol was 4.9 billion gallons and use of 5.4 billion gallons, above the Policy Act requirements.

Spring 2006 Many outboard owners report marine damage and severe engine failure from use of ethanol blend fuels - Investigations reveal gas they used had ethanol content of 15-40%, well about the safe legal limit. See 1995 EPA warnings to boat owners.

1990 Clean Air Act Amendments - Mandated the winter use of oxygenated fuels in 39 major carbon monoxide non-attainment areas (based on EPA emissions standards for carbon dioxide not being met, in areas with unhealthy levels of carbon monoxide. ) and required year-round use of oxygenates in 9 severe ozone non-attainment areas in 1995.

The Energy Policy Act of 2005 established a nationwide renewable fuels standard

requiring the use of 4 billion gallons of renewable fuel in 2006 and increasing to 7.5 billion gallons in 2012.

2005 Under the Energy Policy Act (2005), the EPA is responsible for regulations to ensure that gasoline sold in the United States contains a minimum volume of renewable fuel (ethanol is a renewable fuel).

The Clean Air Act (1990) and Alternative Motor Fuels Act (1988) contain provisions for mandating oxygenated fuel (RFG =Ethanol and MTBE). Requirements set for 2 types of clean-burning gasoline, RFG Federal Reformulated Gasoline and Wintertime Oxygenated Fuel.

2003 to Present Almost ALL states have followed California's lead, banning MTBE, (a few states still have lawsuits pending with the EPA for exemption from MTBE ban), resulting in MTBE being replaced by ethanol nationwide.

Problems with groundwater contamination from the use of methyl tertiary butyl ether (MTBE), the only other available oxygenate and principal octane booster, accelerated the use of ethanol in low-level blends, after 1990.

2003 California began switching from MTBE to ethanol to make reformulated gasoline. California was the first state to completely ban MTBE, effective January 1, 2004.

1999 Some states began to pass bans on MTBE because traces of it were showing up in drinking water sources.

1995 The EPA began requiring the use of reformulated gasoline year round in metropolitan areas with the most smog.

1995 EPA issues public bulletin warning for Boaters using ethanol fuel.

Late 1990's to Present Major U.S. auto manufacturers begin selling Flexible Fuel Vehicles (FFV's), that can run on up to 85% ethanol. About 5 million FFV's/AFV's are on the road today.

More Background/History on Ethanol:

1988 Denver, Colorado, mandated ethanol oxygenates fuels for winter use to control carbon monoxide emissions. Other cities followed.

1980's Oxygenates added to gasoline included MTBE (Methyl Tertiary Butyl Ether - made from natural gas and petroleum) and ETBE (Ethyl Tertiary Butyl Ether - made from ethanol and petroleum).

1975 U.S. begins to phase out lead in gasoline. MTBE eventually replaced lead.

(Note: Later, between 2004 to 2006, MTBE banned in almost all states, due to groundwater contamination and health risks).

1940's to late 1970's Virtually no commercial fuel ethanol was sold to the general public in the U.S. - due to the low price of gasoline fuel.
