5-40 would be better for the hotter weather as the 40 represents a higher viscosity when heated. Problem is, what does your BMW's owner's manual say? If it has any kind of warranty you may void it by using the wrong oil. Try a synthetic blend of full synthetic. They will give you the performance that you are looking for.

I would use 5w40, as it's thicker and will probably offer a little more protection than 5w30 in higher temperatures.

I have bmw320 d 2016 desil engine but use it in UAE hot claimt I don't know which tayp of oil should be using?


Check your owner's manual. All of that information should be in there.
