Please see your car's owners / users manual for all these details. It will contain all the recommendations regarding engine oil grade, change interval, etc.
Whichever engine oil you use, ensure that oil is preferably fully synthetic, 100% genuine and original, and from some reputed brand (like Shell, Total, ZIC, Kixx, PSO, Mobil1, Caltex / Havoline / Chevron, etc.). Fancy, expensive engine oil brands may be avoided.
Use that oil which meets / exceeds OEM requirements and specifications.
