Old car normal la use mineral. Modern car not recommended. But I had bad experience using this shenzo oil for my Myvi. Used it for like 2 years. Worst decision ever. Engine felt sluggish. Then when I did overhaul, mech. found lots of carbon and ask me what kind of EO you use. Told them shenzo they laugh their ass off. 
old car use thicker old because their parts start to get loose and thicker oil can prevent evaporation or leak of the oil.
my bro said got 1 bmw owner bring 2 tong 5w40 shenzo oil to service but the next service change to mobil w50 because the shenzo w40 got burned.. lol probably their engine temperature is too high and burn the oil. The hotter the oil, the thinner it is so they are fine with w50.
now for your myvi, probably anything higher than w30 is not so good for your engine. if the oil is too thick the lubrication wont be good.
