Because the ethanol content in E85 varies between 51 percent and 83, the octane rating can vary as well. Higher ethanol blends burn more efficiently inside the engine, allowing more heat and energy to be consumed in powering the vehicle. Drivers have noticed more torque using E85 compared with dirtier gasoline. Vann, 34, is such a believer in E85 that he entered our contest in October when Pearson Fuels held the grand opening of a station introducing E85 in Desert Hot Springs.
The latest station grand opening is Wednesday the Mobil station in Fullerton. Between 8 a. Even on a normal non-promo day, E85 usually is cheaper than regular gas. Some people convert their gas-only cars to run on E85 by tweaking the on-board computer. Oil companies liked to use fancy petroleum based synthetic octane enhancers called aromatics. While these aromatics do cause your octane to increase they are often harmful to the environment.
One such was MTBE which was eventually banned due to its toxic content. And to top it all off, aromatics are expensive to produce and increase your fuel costs. Really a lose-lose for the most part. In terms of its octane rating, ethanol has a rating of Talk to your local retailers about offering E Financial assistance is available to retailers in Iowa through the Renewable Fuels Infrastructure Program, which is being managed by the Iowa Department of Agriculture.

In comparison, regular unleaded gasoline has an octane rating of What happens if I accidentally fuel my gasoline-powered vehicle with E85? No problems should occur if you mistakenly fuel once with E Long-term use of E85 in gasoline-only vehicles may cause damage because of the incompatibility of high-ethanol blends with parts in gasoline-only engines.
Alcohol fuels can be more corrosive than gasoline. A percent blend is not a flex fuel. The Renewable Fuels Association defines a flex fuel as a blend of ethanol and gasoline that contains more than 15 percent ethanol and less than 83 percent ethanol. According to Cars. They can run on anything from percent gasoline to blends containing 85 percent ethanol. All model standard vehicles and newer can run on E15 but can't handle the corrosiveness of higher ethanol percentages. The Society of Automotive Engineers and other supporters of E85 usage argue that if automotive manufacturers would recognize and take advantage of ethanol-based fuel's superior traits, they could make an ethanol engine that was as efficient as one powered by gasoline.
According to these proponents, an ethanol engine that can reach up to 22 percent more miles per gallon than a gasoline engine already exists. It's wrong, they say, to base ethanol engine design on that of a gas engine when ethanol is closer to diesel fuel. Critics of E85 and ethanol, in general, argue that its lower heating value outweighs any benefits.
Supporters counter that argument by pointing out that heating value does not factor into overall efficiency. Adding a fraction of gasoline to ethanol blends can counteract the low heating value. E85 also has higher octane content, which can provide more engine power. Thanks to an abundance of corn, E85 is only going to become more common in the United States. Increased support and government subsidies mean that E85 and other flex fuels are here to stay.
