"Just bought my first 4-stroke
"Just bought my first 4-stroke motor. Is there any advantage to using 91 octane gas vs 87 octane? I don't mind spending the extra money if it can improve performance or increase its lifespan. And what about synthetic oil? If I change it at the same frequency as regular oil, can I get better performance, or increase lifespan of the motor? If you recommend synthetic oil, which one should I use, Amsoil?
Thanks."
