if the price is almost the same or just rm10-20 higher then why not? or else is depend on ur driving style and mileage. in my opinion, if ur driving style is high rev and/or always travel here and there, is always better for u to go full syn; and vice versa.

for your info my kenari is using perodua engine oil and change every four month when it hits around 8k km with often high rev when i need. so what do u think? 1. money 2. enthusiasm on car
