That has been well documented. I don't know the exact percentages but I'd guess it's 85-90% as effective as an equal amont of gasoline.
The positive is that it comes from a renewable resource. So to have a product almost as efficient as a non-renewable energy source make ethanol attractive. The issue for us old truck guys is what this product does to old seals and such. The ethanol attacks old seals and cause them to breakup.
Most modern seals and items used in today's engine can tolerate the ethanol. The percentage of ethanol in gasoline is only going to increase over time. So better tune up those engines!!!!!
