Incorrect.
According to the Seafoam MSDS for Original Engine Treatment, no ethanol is listed.
Isopropanol, made from Propane, is an ingredient, at less than 25 percent.
Marine Seafoam MSDS lists 100 percent petroleum derivatives. No ethanol.

Add Sea Foam and don’t worry about the gas.

Yea. I made the mistake once of doing a shock treatment on an old Evinrude 150hp looper that was sitting on the trailer right in front of the white garage door. Not a pretty result.

Seems the consensus is to just use SeaFoam and you don't need any other additives. I'll be picking some up shortly. If using SeaFoam, how important is it to run straight gas vs that with ethanol?

In my opionion, ethanol has no place on ANY engine that uses a vented gas tank. It is the vent that allows atmospheric moisture to get sucked in as the air in the tank expands and contracts with temperature changes. I only run pure gas in my motorcycle, lawnmowers, weed eater, chain saw, boat, etc.

Non ethanol fuel and Yamaha Ring Free in every tank full for me. My 115 Suzuki does not burn much fuel so a quart of the stuff lasts 2-3 years. A quart treats 320 gallons. Carbon will kill a 4 stroke outboard eventually.

PURE GAS APP on the phone. used it for years.

Thanks for sharing the link slowhand, I only run 0E gas in my boat, mowers, saws, well any power equipment.
