there are plenty of good reasons it cant be done, namely cars don't run under full load all the time unlike boats. Never mind the fact that the more ethanol you put in the gas the worse mileage you get. Fuel lines, fuel tanks, fuel pumps, etc...I replace fuel lines and clean injectors on a regular basis. If you let your car set for more than 30 days, it will need it as well. BTW, most modern marine engines are running plated bore cylinders and coated pistons that are superior to steel bore cylinders. Ethanol is a horrible fuel, it takes more in diesel to produce it than it makes and it is horribly corrosive. Ive got a buddy that's a Service manager at a large Honda car dealership, they have a steady stream of fuel issues with people running E fuel. The only reason we have ethanol fuel is courting corn farmer votes in swing states. Under Carter, we had gasahol, under Clinton we had Oxygenated fuel(MTBE or ether enhanced, all derived from corn ethanol). Under Obama, we had E10, under Biden we are getting E15. Closed loop fuel systems adjust their fuel mix to make up for this type fuel, increasing emissions, and decreasing fuel mileage(increasing fuel tax). It has nothing to do with emissions, everything to do with buying votes. The only thing you can do to prevent this is pay attention to your votes.
