Not sure, because many oil are local blend or Singaland blend under license. To me under license from owner still okay. Like BHP is local blend now. Last time was Singaland...

Yup, sometimes when engine is worn a thinner viscosity oil will be burnt away especially if drive at higher rpm most of the time....
But if 10w-40 already heavy for you, then 20w-50 will be very very heavy....

Maybe can try 5w-40 first from 5w-30. HKS got a 5w-38......
