Not necessarily. Lubricant quality is also very important, besides viscosity. That is why there are so many kinds of 0W-20, with varying OEM approvals. Vehicles tend to have so many other problems, that if you use a quality lubricant within OEM specifications, you're very unlikely to experience a lubricant related failure, ever. I'm talking about a daily driver, of course. Simple example: I bet that the VNT inside a turbo on this engine will fail due to heat cycling and exhaust crud way before the bearings fails due to "water thin" 0W-20.
The B46 is an ultra low emissions engine, that is why I recommended ESP 0W-30. However, ESP 5W-30 would also work, if approval is a concern. I am reasonably sure that this engine has a GPF. Maybe
@edyvw knows more about this.
