My questions are:
1. Can I add synthetic engine oil or should I keep the conventional one?
2. Should I go with 0w30 or 5w30?
(Considering it's very cold in the winter and very hot in the summer)
3. Should I buy summer engine oil and an additional winter engine oil, or an all-season will fit?
Castrol Edge Titanum Full Synthetic seems to be the best in class
