I was identically in your same situation
the previous owner was suing 20w50 for 60k km
i used 5w30 it was ok but in summer i was not happy with engine sound however i ran for 12k with it
then i tried 5w40 and it was also ok
finally i found in the car catalog that i can use 10w40
so i tried it from amsoil and it is the best for me till
i have been using it for about 4k now
sryfor typing in English as i have no arabic keyboard
