i don’t know why your sales are down,all i know is i have a shop full of these things with bad gaskets mush fuel lines and in some cases pitted aluminn that can’t be fixed.all the additives in the world won’t fix that.
My "sales are down" since they stopped using cast iron piston rings, point ignition and carburetors, and started using chrome/moly rings, electronic ignition and fuel injection.
The engines outlast the sheetmetal (like I said, over 200,000 mi)

That stuff must have been sitting in your shop for awhile, since anything new is built to run on the blended fuel, with maybe the exception of two strokes.
Alcohol doesn't pit aluminum, but the mixture with water might. All my lawn/garden equipment is at least 20 years old, and I doubt that the ethanol is causing my belts, bushings and friction wheels to go to hell. The engines are fine and have never been apart,except for removing float bowls until I figured out the problem.
The problems arises from leaving the untreated fuel in the tanks and carbs.
You can't do that.
