Yes but for climate conditions like pakistan xW40 oils also are fine to use especially in summer and more so if they are recommended in owners manual.
Xw40 oils are also widely used in German cars such as BMW and Volkswagen
Very thick oils would be considered Xw50 Xw60
Honda's outside of Pak also recommend to use either Xw30 or Xw40 oils, so there's nothing wrong as such with using those.
The best way to choose oil viscosity is to see what is recommended in owners manual and follow accordingly.
