Valvoline max life kicks ass.
I've been using 0W40 Euro Formula from Mobil 1 for years in both my cars. You will be fine running it.
As a Mercedes-Benz guy, I've used Mobil One European Formula 0w40 in them for decades. It is very good oil. I have well over a million miles on Mercedes-Benz cars using that oil with the extended (10K-15K mile) change interval with zero issues. Several of my cars have gone over 200,000 miles.
But if you want the short of it:
ANY high mileage full synthetic 5w-30 oil will do great. Mobil 1? Sure. Amazon Basics? Hell yeah. Wal-Mart's Supertech? Send it.
I dropped some 0W-30 Mobil 1 this winter, and my sol with a d15b7 loved it. Made cold starts very smooth, and noticed no reasons not to continue running it.
I've used only 5w30 full synthetic (usually Mobil 1, sometimes others) since I bought mine 15 years ago (D15B7). Using the high-mileage variety nowadays, supposed to help out the old seals etc. Just over 150k miles but engine runs very smooth so seems to be doing the trick.
I'm using "Valvoline Modern Engine Oil" since they have patents and claim to have some chemistry there to keep the valve stems more carbon-free.
I use Mobil 1 synthetic blend HIGH MILAGE 5w-30. I think the high milage formula is the best for these old engines.
