Ethanol and your Vehicle

Ethanol and your Vehicle

E-10

Ethanol helps keep gas pump prices affordable by adding to the overall motor fuel supply in the U.S. In fact, the Consumer Federation of America reports that drivers who purchase gasoline blended with up to 10% of ethanol save up to eight cents per gallon as compared to straight gasoline purchases.

All vehicles can use a blend of up to 10% ethanol. Ethanol is most commonly sold to motorists in the “E10” blend – 10% ethanol, 90% gasoline – which burns cleaner than gasoline. Manufacturers of small engines (boats, lawnmowers) also make their engines compatible with gasoline containing a blend of up to 10% of ethanol.

E85 is an alternative fuel that is made up of 85% ethanol and 15% unleaded gasoline for use in flexible fuel vehicles (FFVs). The flexibility lies in that the owners of FFVs have the option of using E85, straight unleaded gasoline, or any blend of ethanol up to 85%. It is possible, though quite difficult, to convert your non-FFV vehicle to operate on E85, but automobile makers are increasing their FFV lineups each model year.

E-Diesel

E diesel is a blend of standard No. 2 diesel fuel containing up to 15% ethanol and a proprietary additive to maintain blend stability and certain fuel properties, which may total diet comprise from 0.2% to 5.0% of the blend. Currently, E diesel fuels are considered experimental and can be used legally in off-road applications. Special permission must be obtained from the U.S. Environmental Protection Agency (EPA) for on-road use.

Tests have shown that E diesel blends may reduce certain components of exhaust emissions compared to regular No. 2 diesel, especially particulate matter. The ethanol in E diesel blends is also a domestic renewable resource. The use of greater volumes of ethanol reduces crude oil imports and results in lower contributions to greenhouse gases.

E diesel is made by splash blending of conventional diesel, fuel-grade ethanol, and additives. No special mixing protocol or temperature control is required.

E-10 Unleaded

E-10 Unleaded is a blend of 90% ordinary unleaded gasoline with 10% ethanol. E-10 Unleaded is a high-octane, clean-burning fuel made from corn and other grains.

Environmental Benefits

E-10 Unleaded with ethanol burns cleaner than ordinary gas and reduces toxic emissions from your tailpipe. E-10 Unleaded is keeping air cleaner in cities throughout the U.S. Since ethanol is made from renewable resources, we can have a constant supply, unlike fossil fuels that are in limited supply and shrinking rapidly.

E-10 Unleaded reduces emissions of carbon monoxide and other toxics that pollute the air. The use of E-10 Unleaded also helps offset greenhouse gas emissions caused by burning fossil fuels. In addition, E-10 Unleaded is biodegradable and does not contaminate ground water supplies.

E-10 Unleaded And Your Automobile

Every major car company in the world approves the use of E-10 Unleaded under warranty, and many manufacturers actually recommend that you use E-10 Unleaded because of its clean-air benefits and high-performance qualities. Harley-Davidson, Briggs & Stratton, and Honda – just to name a few – recommend the use of E-10 Unleaded. Some of the major automotive benefits of E-10 Unleaded with ethanol are the following:

  • The ethanol in E-10 Unleaded adds two to three points of octane to gasoline, thus helping to improve engine performance while keeping engine parts cleaner. It does so using a natural, renewable additive that works as well in older engines as it does in newer ones.
  • The ethanol in E-10 Unleaded helps keep your engine cooler because the ethanol (alcohol) in the fuel combusts at a lower temperature.
  • The ethanol in E-10 Unleaded keeps fuel injectors cleaner-helping improve engine performance. It does not increase corrosion, nor will it harm any seals or valves.
  • The “cleansing” nature of E-10 Unleaded with ethanol can actually keep your fuel system cleaner, leading to improved performance.
  • E-10 Unleaded is perfectly acceptable in lawn mowers, snowmobiles, and other small engines, and may be used anywhere that unleaded gasoline is used.

Glossary

AGE 85:

Aviation Grade Ethanol used in piston engine aircraft. It contains 85% ethanol, along with light hydrocarbons and biodiesel fuel.

BIODIESEL:

A renewable fuel in which soy oil is blended with standard diesel fuel and other additives. Research is underway to develop diesel blends with ethanol.

BIOMASS:

Plant matter such as trees, grasses, crops, and other biological material.

CARBON MONOXIDE:

A deadly gas produced from the tailpipe when cars burn gasoline. Ethanol in unleaded gasoline helps reduce carbon monoxide emissions by as much as 30%.

CLEAN AIR ACT:

In 1990, Congress passed amendments to the Clean Air Act, which set minimum standards for air quality in American cities. Cities with excessive amounts of carbon monoxide and ozone must develop programs to battle air pollution.

CO-PRODUCTS:

Other products made by ethanol plants as a result of ethanol production. Co-products may include livestock feed, corn sweeteners, corn oil, and carbon dioxide.

DRIED DISTILLERS GRAINS (DDG):

A dry mill ethanol production co-product that is fed to livestock; also referred to as DDGS (dried distillers grains with solubles.)

DRY MILL:

An ethanol production process in which the entire corn kernel is first ground into flour before processing. Dry mills also produce dried distillers grains with solubles (DDGS), which is fed to livestock, and carbon dioxide which is used in food processing and bottling. Most new ethanol plants are dry mill facilities

E-10 UNLEADED:

Ordinary unleaded gasoline enhanced with ethanol, which is blended at a rate of 10%. E-10 Unleaded is approved for use by every major automaker in the world.

E85:

A blend of 85% ethanol and 15% ordinary unleaded gasoline that is used in Flexible Fuel Vehicles.

E-DIESEL:

A blend of ethanol and diesel fuel plus other additives designed to reduce air pollution from heavy equipment, city buses, and other vehicles that operate on diesel engines.

ETBE:

Ethyl tertiary butyl ether; a fuel derived from ethanol that offers advantages in terms of lower volatility and blending.

ETHANOL:

A clean-burning, high octane, renewable fuel additive made from grain or other biomass sources.

FLEXIBLE FUEL VEHICLE (FFV):

A car or truck that can run on any blend of unleaded gasoline with up to 85 percent ethanol. A computer in the fuel system automatically compensates for the varying levels of ethanol in the fuel to assure optimum performance at all times.

METHANOL:

A fuel additive made from fossil fuels such as coal, petroleum, and natural gas. Many car warranties do not cover the use of methanol-based fuels, but all do approve the use of ethanol blends.

MTBE:

Methyl tertiary butyl ether; a fuel derived from methanol that has been discovered in groundwater supplies, thus leading to legislation banning its use in many states.

NET ENERGY BALANCE:

The difference between the energy produced and the energy it takes to produce it. Research has shown that ethanol has a net energy balance of 1.67 to 1, meaning that for every 100 BTUs of energy used to make ethanol, 167 BTUs of ethanol are produced.

OCTANE RATING:

The octane rating of a fuel is indicated on the pump, using numbers such as 87, 90, 91, etc. The higher the number, the greater the octane rating of the gasoline. The octane rating represents the “antiknock” properties of the fuel. The higher the number, the slower the fuel burns, and the less likely your engine will knock.

OXYGENATED FUELS:

A fuel such as ethanol-blended gasoline that contains high oxygen content is called “oxygenated.” Ethanol is an oxygenate, meaning that it adds oxygen to the fuel mixture. More oxygen helps the fuel burn more completely, thereby reducing the amount of harmful emissions from the tailpipe.

REFORMULATED GASOLINE (RFG):

A cleaner-burning blend of gasoline that reduces motor fuel emissions. RFG reduces some of the more harmful, toxic compounds and adds more combustible, cleaner-burning compounds. As a result, RFG can be efficiently, safely, and cost-effectively used in today’s cars—using the same refueling methods and with no appreciable difference on vehicle performance. Since 1995, RFG has eliminated approximately 300 million tons of pollution from the nation’s atmosphere.

RENEWABLE FUELS STANDARD (RFS):

Part of proposed federal energy legislation that would set a minimum number of gallons of renewable fuels to be used in the nation’s transportation fuel supply each year. The RFS would include fuels such as ethanol and biodiesel (soy diesel).

VAPOR LOCK:

An engine performance problem due to high vapor pressure in fuel. While ethanol increases the vapor pressure of fuel, state and federal standards continue to lower vapor pressure levels, virtually eliminating vapor lock problems. All major auto manufacturers now use in-tank fuel pumps, which are not subject to the vapor lock problems seen in older in-line fuel pumps.

VEETC:

Volumetric Ethanol Excise Tax Credit; 2004 federal legislation that strengthened the nation’s commitment to renewable fuels by extending tax incentives for ethanol and biodiesel, improving flexibility for petroleum companies to blend ethanol, and ensuring that Highway Trust Fund revenues are not adversely affected by increased ethanol use.

VOC:

Volatile organic compounds (VOC) emissions are air pollutants found in engine exhaust and are reduced by 12% with ethanol use.

WET MILL:

An ethanol production facility in which the corn is first soaked or “steeped” in water before processing. Wet mills also have the ability to produce co-products such as industrial starch, food starch, high fructose corn syrup, gluten feed, and corn oils.
