It must be frustrating. No auto maker uses unrated, unproven oil in their vehicles.
Must be frustrating that most of them use dino oil for their low/mid range vehicles.
Must be frustrating that, for example, Porsche factory fills with Mobil 1. BMW with Castrol, or Ferarri uses Shell.
Must be galling that despite your claims, dino or Grp III oils are being used by thousands upon thousands of vehicles with no problems.
