It's personal choice at the end of the day what you put in your bike, synthetics have many benefits but perhaps more so if you intend to keep the bike for many years or it is modded or driven hard on track etc.
I never said that dino was not fine, it will always be if changed regularly before it has a chance to degrade.
My biking days are over, I'm into cars that rev to 9500rpm now
