It don't believe it suggests that star polymers are significantly worse. Sure OCP performed a little better for the test but it's still just a test. There are other tests where OCP does worse so it's a constant balancing act between competing objectives. An other thing is that the additive package (High Moly, or avg detergent) had an even larger impact than the type of VII used.
Edit: What
@buster has really shown us is that one should not use aftermarket moly additives in your turbo engine unless you change the oil more frequently.
