Re: 1984 20hp suzuki oil ratio

Hey, Mikey.<br /><br />Back in the 80s OMC, Yamaha and Suzuki all went to a 100:1 ratio.<br /><br />Reliability suffered, and some internal corrosion was reported in engines that had been stored after running 100:1.<br /><br />OMC backed off and changed to 50:1. I don't know about Yammy and Suzi. <br /><br />I would still run 50:1 unless I was going to go to 100% synthetic, and then I would still use 50:1 in the last tank of the season.<br /><br />Good luck. :)
