No surprises here. We all knew here that Mobil1 0W40 is shear stable for an off-the-shelf, readily available oil.
Also, no surprise that Castrol Euro 5W40 sheared more than M1 0W40. IMO, and I always claimed this, Castrol Euro 5W40 was never on par with M1 0W40. It would be interesting, though, to see how Castrol Euro 0W40 and 0W30 would perform.
Other tests were no surprise, though what caught my attention was difference in star polymers between two suppliers.
