Mercury Debunks More Ethanol Myths

Mercury Marine, the world's largest manufacturer of marine engines, recently held a webinar to debunk some of its own myths about ethanol. I attended with interest. The first myth was that there are fuel additives that can prevent all issues associated with ethanol-blended gasoline. For example, no fuel additive can prevent ethanol from acting like a solvent. The second myth was that fuel additives can make stale or phase-separated fuel useable. "Fuel cannot be rejuvenated," Mercury determined, and they noted that it's a myth that ethanol-blended fuels are bad and should be avoided. Here are some quotes from the Mercury Marine webinar.
• "There is no active transfer mechanism for ethanol molecules to reach out and 'grab' water molecules out of the air. Under normal storage conditions, even in a vented fuel tank, it just does not happen at a level or rate that is relevant."
• "Major multi-billion dollar companies with enormous resources have improved gasoline additives but there have been no recent breakthroughs involving 'magical technology.' Claims made by companies about 'space-age,' 'revolutionary,' or special proprietary technology should be looked at with a high degree of suspicion."
• "E10 Ethanol absolutely IS an acceptable fuel for everyday use."
• "E15 Ethanol absolutely IS NOT an acceptable fuel."
• "After the transition period from E0, E10 may actually be a superior marine fuel as it tends to keep low levels of water moving through the fuel system, keeping the system 'dry.'"
• "Don't immediately assume E10 is the problem."
