greetings, i have always had used synthetic oils in my vehicles, recentlyy got a brand new scooter, gy6 engine, mostly the standard for al chinese bikes, i immediately added motul synthetic oil, with the viscosity marked in the users manual, the scooter runs just fine,BUT i have been seeing in some youtube channels people saying that synth is no good for these cheap engines, i feel kind of concerned when i see videos of bike mechanics saying that your engine may blow if you use synth in engines smaller than 750cc or super fast bikes,
i would like to know the opinion of well informed people and or personal experiences in this matter what are your thoughts?
