[I]the question about best engine oil is very interesting and provocative.
the issue is that mineral oils are gud but if u are using 125cc or higher then u wish to use a better oil like semi or fully synthetic.
the problem though with using synthetic oils is that bikes use wet clutch system and synthetic oils ruin the clutch plates beacause synthetic oils were primarily made for cars which have a separate transmission oil and thts y u can use synthetic oil in cars.
if u want to use synthetic oil in bikes then the oil must satisfy JASO MA standard which shows that the oil is also suitable for wet clutch systems.
only two oils are currently providing it
1:- Castrol Racing 1T (fully synthetic, 10W-40, JASO MA)
2:- ZIC 4T (fully synthetic, 10W-40, JASO MA)
so guys i recommend u use any of the above. i have a Piaggio Storm 125cc Euro2 and i am using ZIC 4T... Bike is running like a charm
Hope it helps u guys[/I]
Should I use synthetic oil for my Unique UD100??
