What oil type do I use? 2016 GL 450

Hello, I have a 2016 GL 450 with V6 Turbo. I am in Florida and want to know if 5W-30 is fine for this car? The car is 160k miles would appreciate your feedback on what oil type is best for the car, thanks.

What does your owner's manual call for?
If you go to a Mercedes parts site like FCPEuro, what do they offer for your car?

Second BlownV8- only run 5W/40 full synthetic type M and change every 4000 miles. Once above 150k miles, change every 3,500 miles.
My GL 550 has 223k miles and you can actually hear a difference in the engine rotating resonance after 3k miles. There is also a distinct smell associated with the oil when it comes time to change it b/c turbos share same oil. Get to know it. When changing oil filter element, look for any particles under and within filter after removal while fluid hot/warm. Let oil fully drain for 25min. Fill oil to precise top level, though better to have a bit less oil than more - refill to top level after driving 3-5 miles. Always change out the copper washer on the oil drain plug.

10K oil changes with over 500k miles on my GL's. No oil related issues ever.
