Fuel Stabilizers for Gasoline and Other Information

According to the U.S. Department of Energy, E10 is a low-level fuel blend made up of 10 percent ethanol and 90 percent gasoline. Ethanol-blended fuel is sold in all 50 states and accounts for about 1/3 of all vehicle sales. It's intended to produce a higher octane rating than regular gasoline and reduce greenhouse gas emissions.

Since the mid-1980s engines use fuel injectors with computers to accurately control the air/fuel mix over all temperature and environment ranges. The accuracy of the fuel injectors and computers is based on using the recommended gasoline for that engine. Most cars are designed to burn regular unleaded gas with an octane rating of 87. If the vehicle needs a higher octane rating this requirement is noted in the owner's manual and usually under the fuel gauge and by the gas tank. You should always check with the manufacturer for the recommended grade of fuel to use for your vehicles and equipment.

Information Regarding E10

Gasoline Factors That MatterThe quality of gasoline and the additive package usually affect the rate of engine wear more than the octane rating. Basically what this means is that it matters more where you buy your gas than which grade you purchase.Regular Unleaded GasolineThe recommended gasoline for most cars is regular 87 octane. One common misconception is that higher octane gasoline contains more cleaning additives than lower octane gas. All octane grades of all brands of gasoline contain engine cleaning detergent additives to protect against engine deposit build-up. In fact, using a gasoline with too high of an octane rating may cause damage to the emissions system.Mid-Grade GasolineThe octane ratings 'regular', 'mid-grade', and 'premium' are not consistent. In the United States, for example, one state may require a minimum octane rating of 92 for premium gasoline, while another may allow an octane rating of 90 to be premium. Check the octane rating on the yellow sticker on the gas pump rather than relying on descriptive labels.Premium GasolineCertain high performance engines benefit from use of high octane fuel. For other engines, using a fuel with a higher octane rating than the vehicle requires sends unburned fuel into the emissions system and catalytic converter. This puts unnecessary stress on the emissions system. For some vehicles, a rotten egg smell coming from the tailpipe signals use of too-high octane gas.Since January 2009, Oregon State mandate has required all gasoline must contain at least 10% ethanol (E10) but due to problems with engines in marine, aviation, yard equipment and older model cars, premium "clear" gasoline was made available at some stations on January 1, 2010. MNOP has non-ethanol premium gasoline available at our Claxter Road location. The state mandate for use of E10 fuels enacted by Gov. Ted Kulongoski was passed by the 2007 Legislature. But legislators from both parties heard testimony about reduced engine efficiency and engine and fuel system damage from ethanol. After some debate and fine tuning, the bill was assigned HB 3497 and passed.

Five states - Minnesota, Missouri, Montana, Hawaii and Oregon - have laws mandating all gasoline sold in their states to be blended with a 10% ethanol mixture. Florida become the sixth state in 2011 to have the same requirement, but repealed their E10 law on July 1 of 2013 and no longer require all gasolines to have a 10% ethanol mixture.
