When was the last time you saw a new vehicle catastrophically fail? GM aside.

Do Volvo XC90's within the warranty period count?

Recent model years?

Look I own a Volvo. I'm not getting in a spitting contest with a topic that has been beaten to death. Do you own a Volvo? I just had some big buck repair done-under warranty (2022 XC60). If you want to gamble because you think you know better than the engineers who design these (expensive) vehicles-go right ahead. It's also a warranty issue that covers the vehicle bumper to bumper with inspections along with that oil change (As I stated earlier.)

As I thought.

Volvo has strict inspections for warranty requirements. The OP is foolish to change the oil on his own-or use any oil other than what's stated in the owners manual. There is no middle ground here. Every ten thousand miles there is an oil change required and various items that are to be inspected.

People can change their oil early, and still do the 10k change/inspect. Nothing foolish about this.

Regarding "engineers know best", it's true, but engineers need to design around product planning and regulatory requirements. I'm an engineer, and I know for a fact that outside requirements often cause design compromises. Oil viscosity is a perfect modern example, since CAFE forces the decision over what the engine designers would pick if given their own choice.

Agreed. The engineers today are investing their time and effort to ensure thinner grades of oil do not cause excessive wear. It doesn’t mean those grades are required nor optimal for wear.
