that was a turbo application if we are referring to the same sample. I think the turbo killed that oil in that one test. Check out the oil analysis spreadsheet from BillGXE, none of the 5w-30 Castrol samples sheared down that much in 3000-4000 mile drains. I think they all stayed in the high 11's from intial mid 12's starting point, not bad IMO.quote:

Um, didn't someone post a result here a month ago showing that castrol GTX 5W30 sheared down to a 20 in just a couple thousand miles?
