@rajaatta bahi Eid Mubarik,
Regarding new Honda city 1.5 auto engine oil change at 1,000km, I met a friend, he works in Honda center, he told Honda factory put 0w20 oil in the new manufactured car from factory and at 1,000km oil change/service interval Honda center, replace it with same 0w20.
Knowing this, should I keep with 0w20 or as you suggested with 10w30 for initial breakin and engine oil change at 1,000km oil change, the Honda logic
