I’m the original owner of my 2005 Acura TSX 6MT with nearly 272k miles. Average oil change interval throughout the life of the car averages to be about 7,500 miles mostly using Pennzoil Platinum 5W30 and quality filters such as Fram Ultra Synthetic. Car is driven about 70/30 Hwy/City. And runs absolutely perfect. Prior UOA was at 100k which is also listed. This is my most recent UOA which lists lead and copper as concerns. Are these values something to be concerned about, or normal for this mileage? I appreciate you opinions…
