Re: What octane
Stick with what Yamaha recommends. If they say 87,stick to it.<br />Octane is misunderstood by many people. <br />They think the higher the octane, the more explosive the air/fuel mix, when in actuality, its reverse. The higher the octane number, the LESS explosive it is.<br />If you hear any "pinging" goin-on while underway, stop imediately,and add octane booster until the tank is empty. Then go up on the octane number.<br />Also, higher octane fuels,by burning slower<br />and cooler, to carbon-up the innards,and foul plugs.Stear clear of fuels with alchohol in it,as it devours the fuel pump diaphram,and all other rubber parts in the fuel deliviery system.
