I am not aware of a law the we must use 15. Not sure where the 4 gallon minimum comes from. I know EPA permits the sale of E15.

I am with you, I want it all to go away. Driving our food is simply a stupid thing to do.



If you click on the headline at the AMA link a further and longer explanation is given. The problem seems to be that, residual E-15 in blender pump hoses won't dilute enough in tanks smaller than four gallons, so the vehicle can get a relatively large dose of ethanol. I guess it could be even worse by just topping off. Unfortunately, no ATVs or motorcycles are on the official E-15 approval list, in which case can release manufacturers from engine failure warranties due to excessive ethanol use. Excessive ethanol use cause engines to run hotter than designed for and can lead to premature failure.

If I understand it correctly, most newer autos' engines are designed to run on E-15, but unfortunately at this point in time the US passenger car fleet is older than anytime since the statistics have been collected. What could possible go wrong?
