Second UOA on car. Chevron Supreme 5W30 ran for 4,427 miles. Oil filter was a Fram Ultra that had a run of Castrol Edge EP 5W30 and two Chevron 5W30 for a total of 17K miles on it. I have 12 more 5 Quart jugs of Chevron Supreme 5W30 that I am going to run with the Ultra with 5-6000 mile oil changes and change out the filter every third oil change.
First UOA was Supertech 5W20.
