I don't have any credentials on the topic but I've tracked Ethanol inefficiencies for years in my vehicle. I tow often (between 3000-7000lbs) and my tow vehicle has the capability to run up to 15% ethanol. On average, over the last 7 years, I will lose on average 30% tow range and significant power loss at 10% ethanol. Ethanol has rarely ever been cost effective but it's also harder on engine components because of the less efficient power cycle and quicker buildup in the downpipe of the turbo system in my vehicle. I monitor other engine vitals with an OBD reader while towing and my engine cycles through thermals faster when running Ethanol as well - the engine gets hotter faster because Ethanol burns hotter, but the BTU output is less - leaving me with that less efficient power cycle. Overall Ethanol is a complete detriment to any and all IC operations. And don't even think about using Ethanol in any 2 stroke motor. Not only will it basically destroy your motor in record time but it's the worst type of fuel for fuel delivery systems that may not be used on a daily basis. Ethanol and all the ridiculous subsidies tied to it are one of the biggest rackets out there. It's been known from the beginning that the only thing it's good for is wasting valuable crop land. If it were actually useful we wouldn't need to continue to subsidize corn production for its use decades later. Ethanol is a joke.
