My contribution to the new game:
"In my particular oil company the selection of oil from a Car manufacture is generally managed by marketing or b2b. Not the car labs performance centres. Its not hard to see which car manufactures have a contract with which oil suppliers, porsche - exxon- mobil, Ferrari - Shell, Merc- Mobil or Total depending on what car and sponsorship deal. Yes there is different spec oils from all these manufactures which may aid certain aspects of that engine design, but really is a high performance ferrari engine really that different to a high performance porsche engine that a particular brand is better. Spec of oil is much more important then the brand.
To further explain my logic. There are refineries for all super majors, some of them shared/JVs some of them do have IP tech. But they all trade(for gasoline the oil barrel has been traded around 30x before you buy it) additives are added before they reach retail stations to differentiate. Do you really know which refinery made your bottle of oil? yes it will be made to manufacture tolerances. but original oil/feedstock could be quite varied and refineries quite operationally different."
This is why I prefer a small, independent formulator with a specific and deep involvement in the M96 .And they offer free UOA via RND . Does your big name oil company do that ?
