Put this in a car yesterday. Wonder why it specs such an oil?

What kinda car? A pushrod V8 in a 4x4 truck or an air cooled VW or Porsche?
Must have been a German car or some Euro supercar.

Guessing BMW M5 V10
BMW used it in some of their M cars as a band-aid for bad bearings
Ferrari has used it in some of their cars, but I think they switched to 5w40 for their newer cars.

Probably S65 or S85.
I’ve seen it in an old Porsche calendar
Or S54 or S62
M6 and ya a v10
I have the same car, with a 6-speed manual. I use Redline 10w60. No problems with it's bearings in 13 years.
How many miles? If the owner doesn't know, they eat rod bearings for breakfast. If over 100k miles they should replace them as a preventative measure.
Iirc about 80
Yeah I suggest they do some research. These engines blow up at an alarming rate at higher mileage. A few guys got together and got Clevite to make them a custom part with slightly tweaked clearances and a silver oxide coating that seems to hold up better (BE Bearings).
BE-Clevite Connecting Rod Bearing Set - E60 M5, E63 M6, S85 V10
Designed using correct materials and proper tolerances for the S85 V10 for an upgrade over the Genuine BMW rod bearing shells
Hoo boy you touched it last!
I'm just going to guess that any bearing issues are from mechanically clueless owners, or those that just don't care (Valets, lot boys, etc.) revving the engine hard, while still cold.
My S85 sees redline every time it's driven, just to listen to that V10 howl. BUT, it is always brought up to full operating temp before doing so. If I ever have to replace bearings, I'll mention it.

I think that's a big part of it, but BMW put some VERY tight bearings in the S65/85.

Here is a picture of the bearings I removed from my M5 with 106k miles. While the car still ran fine, I'm glad I changed them.
You won’t know you have to replace bearings until you throw a rod. It’s really not a question of if but when on S85. It’s very well documented. I’ve seen 30+ sets of bearings from S85s from various sources over the years and not one looked normal, and I mean BMW normal not Toyota normal.
With that much copper you were on borrowed time!
