Get yourself some “Ethanol Shield” stabilizer. Available at Home Depot. I saved a new generator with their product “Mechanic in a Bottle” after using Stabil that failed.
Best I’ve ever used and I’ve used ALL of them. A distant second is “StarTron”.
Stabil is garbage.
I’ll even use the manufactured fuels for chainsaws or any sporadic use engine.
I’ve stored equipment for over two years with Ethanol Shield treated fuel with no problem.
Thanks for the tip. I’ve been using Stabil in my non-ethanol fuel cans.
