Throughout the active season we add 1/2 oz of Yamaha Ring Free to every 5 gallons of gas (no ethanol, 87+ octane). Will it do any harm if we also add an additional 1/2 oz of Marine Sta-bil fuel additive along with that Ring Free? (we double/triple the Sta-bil for winter storage, my question is just about the normal running season).
Thanks for your opinions!
