Ethanol myth busting

Ethanol has a powerful defender in Bobby Likis. For 21 years, he’s hosted a car-talk program, plus he’s run an automotive repair shop for 41 years. In October, Bobby Likis Car Clinic live did several sessions at CARS 2012 in New Orleans (the Congress of Automotive Repairs and Service), that are now available on the Car Clinic Network website.  

My favorite was “Ethanol Myth Busters” – featuring several speakers addressing some of the myths surrounding ethanol, followed by a Q&A with auto mechanics attending the National Automotive Service Task Force session. Needless to say, it got into some the technical details that, not being a mechanic myself, I can barely follow. If you understand such things, you might get some of your answers by listening to the various interviews.

Likis digs into the oft-repeated myths surrounding ethanol, saying that in 41 years in the business, he never once saw an engine fail due to ethanol. “What I saw was the cleaning out of fuel tanks, the cars we fixed stayed fixed,” Likis said about the early days. “People say ethanol ruins engines. I would say people ruin engines, not ethanol.”  After 30 years of ethanol blends, he added, all engines are built for E10 and newer ones will handle E15. As for boats and small engines on E15, Likis said underuse is causing issues more than the ethanol content of the fuel.

Those of you interested in ethanol-optimized engines will be interested in the remarks from Dr. Matty Vint, chief engineer, powertrain controls, Ricardo Engineering. He said yes, ethanol has less energy content than gasoline, but the fuel economy of ethanol blends is not direct related to energy content. “Under real live testing of E10, vehicles average 1.4 percent less in fuel economy,” he said. “Tire pressure has more impact on mpg.”

The new federal CAFE standards are calling for a doubling of fuel mileage performance, which, Vint says, is going to send OEM’s looking for high octane numbers to improve efficiency and ethanol is the best source.  Ricardo, an engineering firm with over 100 years in the business of engine design, has developed an extreme boosted direct injection engine (EBDI) to optimize ethanol blends. The 3.2 V6 gasoline engine rivals the power and torque of a much larger GMC Sierra 6.7 diesel, he said, and it delivers 3.5 percent better fuel economy than the diesel.

The educational outreach at CARS 2012 was a joint effort involving Ricardo Engineering, the Renewable Fuels Association and the Bobby Likis Car Clinic. The RFA and Ricardo manned a booth and appeared in several segments filmed by the Car Clinic crew. You can watch segments on the Car Clinic Network including the “Ethanol Myth Busters” session, plus interviews with Matty Vint, Ricardo; Kelly Davis, RFA director of regulatory affairs; John Kasab, chief engineer, innovations & chemical technology, Ricardo Engineering; Chris Talwar, senior director, business development, Ricardo Engineering; plus several other organization leaders attending CARS 2012.

    The real problem I have with ethanol is the corn growers and Renewable Fuel lobbyist continue to force Americans to buy their product(with a mandate)with no freedom to chose what is best.And do not allow the free market work the way it should. This is a UN American way to do business. If ethanol is a good product they would not need the mandate to sell it. Sorry but this unfair, UN American way of marketing really bothers me.

    RE: The above comment... The ethanol industry would LOVE for the free market to control how renewable fuels are embraced by consumers. Every indication is that most consumers prefer it because it's cheaper, home-grown, clean and renewable. There are two problems though: 1. There is currently a 10-15% cap on how much ethanol the industry is allowed to blend into fuels. 2. The oil industry is not subject to the free market approach. Various regulations and subsidies in the oil industry mean that until both fuel options are allowed to compete openly in a free market, the relatively young biofuel industry needs some kind of "toe in the door" protection to insure that it (and other renewable sources) have a fighting chance at upsetting the status quo.

    Evangers Dog Food wrote an interesting post today onHere's a quick ecperxt Has anybody but me noticed what has happened in the last few months? Beer prices have gone up, way up! I last bought a six pack of Dead Guy Ale for about 7 bucks, now it is over $11! Anybody else know why? Because they are using all of the corn,wheat, and barley, etc, for making methanol, to mix with gasoline! Hey gas prices at $3.00 a gallon is one thing, beer at $11 a six pack is another! We need to all understand that when you take something from one place, it comes out of another! Thes
