I'm glad some Folks have had luck with it. I've got several pieces of yard equipment in yard equipment garage that are ruined from it. The carburators or the most part but also other ruined parts.
Some equipment the parts are no longer made for.
Alcohol burns hotter but less power. My weed eaters and Brush cutters say not to use E5. They also prefere 93 octane no alcohol when run at full speed.
Big mower says E5 is allowed as does all equipment now. EPA demands the label.
But I won't risk it in 18,000.00 mower to make EPA happy Corn Farmers rich.
Where they work on my small engines has a room full of small engine equipment destroyed by Ethanol, parts no longer available etc so the Customers just leave them.
Perhpas, up north, the winter freeze removes all,of the moisture from the air but it won't stop hydrogen emnbrittlement.
