I was genuinely curious if any one manufacturer did the whole process start to finish themselves. .....
ram_man, Nevermind the mental nut-jobs like SteveSRT and dave1251 who often do this.
Certainly Mobil, Shell (Pennzoil, Quaker), and Castrol formulate their own oil. Possibly Chevron (Havoline) as well to a high degree. They specify what they need, then have some in-house patents to draw from, and the rest they buy from Dow, Monsanto, Noria, etc.
Its important to note there is no real market advantage in exceeding oil performance specs (SN/GF-5/dexos1/HTO-06/etc.) a particular oil is marketed for, making it easy to just take up the offers from Noria, Lubrizol, or Afton to contract out a formulation completely that qualifies for a spec you want. Thats likely what SuperTech Warren oil does, as just one example.
