I have 06' twin yammy 200 hpdi's. What oil is recommended? I'm the new owner of a 25' 1990 sailfish and want the best possible oil for the motors. I tend to like synthetics for all my motors.(cars, trucks, etc.) And was wondering if it is best for two strokes. I figured I'd start here since this forum seems to be the most knowledgeable around. Any assistance would be greatly appreciated. Thanks, new grady owner, Splash
