Hello guys, i own a Celerio AMT. Its manual recommends 0W20 oil. So i plan to put full synthetic engine oil after 10000 km or 3rd servicing. After asking about 0W20 oil, the SA told we use 5W30 for petrol cars, synthetic or mineral is your choice.
. I saw a mechanic in the Maruti workshop pouring 5W30 part synthetic oil by Castrol in a Alto k10.
What should i do? Any suggestions?
