    I ran reg 87 none ethanol gas in my 2006 250 HPDI. From time to time i might put some mid grade 89 to up the octane if had not used my boat in a few weeks. Always have treated my gas with Yamaha ring free and Sta-bal

    You need to run 91 octane along with ring free. Make sure the oil pump replaced, should have a white dot on it.
