When in doubt always use mid-grade. Additives are like Ford or Chevy. You can use Yamaha ring-free or 28 others. I prefer Sea Foam because it does everything that the others do + it is a real good fuel preservative. Keeping fuel good for 3 years.

87 octane( maximum 10%ethanol) and 1 ounce of Yamaha Ring Free per 10 gallons as insurance. Though the ring free isn't required per the owners manual. If you don't use the boat often, then sea foam or stabil 360 marine is a wise choice to stabilize the fuel a little.
