I was referring to engines in general. My Mercury outboard is only 3 years old and E10 gummed it up bad. My generator is older and E10 shut it down. My son’s husquevarna chainsaw (~5 years old) also had to have work. All blamed on ethanol.
A 3 year old engine and the manufacturer hadn’t engineered it for ethanol? Ethanol has been part of our fuel years longer than that.
I think your disgust is aimed the wrong direction.
Ethanol, good, bad, or indifferent, is what that engine was going to use, and for the engineers to pretend otherwise was immoral, unethical, and I’d say damn near criminal.
I’d raise holy hell with Mercury.
