Re: Yamaha HPDI's
87 octane, alcohol-free unleaded, or what your manual says to use, Runner. No manual? You need one. Get one. <br /><br />I used that in my Suzuki 4 stroke for a few years and she ran fine. <br /><br />Now I use 91 or better so that I don't leave many leftover gallons in the tank for the long periods when she is not in use. With 4 strokes there are always leftovers. I now transfer the leftover to my tow vehicle which requires premium.<br /><br />Good luck.
