People must be using the old red, not treating the gas as soon as it’s bought, or letting the Stabil go bad in the bottle. Ethanol isn’t anything new, if anything it’s getting worse with e15 blends being pushed. People tell me of these fuel problems they have and I tell them Stabil 360 is the solution. Weird to see these problems when the answer has been around so long. Be sure to use enough, get the bottles with the measuring cup built in.
