Yes its recomended oil for this engine.
But so are other grades. So one should chose the grade according to the temperature and atmosphere of where he is operating the car.
In London on fuel cap of 2zrfe , using 0w20 is mentioned as the temperature remains cold there.
In pakistan as the weather is mostly hot
Instead of lowering and using a low winter grade of oil i think it will be a wise choise to increase the summer grade.
