Mechanic certification focuses intensely on engines themselves， and the mechanical aspects of engine parts.It makes sense， then， that mechanics are just as susceptible to believing myths surrounding ethanol as consumers are.Andy Randolph， technical director for ECR Engines， says the Automotive Service Excellence outline for curriculum at tech schools doesn‘t include fuels and their impacts on engines."It‘s not a question on the exam.It‘s not really a part of the curriculum.It‘s kind of surprising， but it‘s an area that burgeoning mechanics aren‘t exposed to."Randolph speculates that fuel impacts aren‘t included in the curriculum because E10 is"the fuel."There aren‘t options， he says."So the fuel is kind of a given and it‘s not something they talk to mechanics about."But fuel options will change with a wider adoption of E15."So， now， getting into the realm of E15 and， hopefully， as time goes on， getting more choices that are higher ethanol blends than that， it‘s really incumbent on mechanics to help educate consumers on what the differences of these various ethanol concentrations are."
