It was what was showing in the original manual for the car.

Was that a modern listing for a W123 or a rating for modern cars?

I know that my OM616 and OM617 engines would easily start down to 0° F with
Mobil one back in the day vs very hard to start below freezing with Castrol
20w50.

The original oil specs probably were not for synthetic. Synthetic 15W40 should
be good for lower temperatures.

In looking thru the manuals on this 123, the manual shows 15w40 good down to 23
where as later and I believe current oil charts show it good down to 5 IIRC.
Why such a big difference from back in the old days? Is 15w40 today that much
better and can be used at lower temps than 15w40 from 40
