I use Tesco 20w50 mineral based engine oil and mix with RTR Engine Treatment Booster Oil only. The engine responsiveness is very good....and the total cost is almost similar to a bottle of semi sync. around RM 110 only.....

Depends what engine you used in. 20w-50 viscosity is heavy and used on old worn engine will be good. If new engine you will be better off on semi 10w-40 or even 10w-30
