This is the second UOA on this vehicle.
The first numbers are from the first UOA using Redline 10w40 with 4131 miles on the oil. The second numbers are for this UOA using 4 qts. Redline 10w30 and 1 qt. Redline 20w50 with 4982 miles on the oil. Vehicle had total of 35050 at time of this UOA. I may have driven the car a little harder this time around, as in revving to redline more often, but otherwise driven about the same.
