Blackstone comments:
Universal averages show typical wear levels for Toyota's 1.8L engine after 5,000 miles on the oil. You ran this oil 4,169 miles and above average copper, lead and silicon showed up. If your engine has had work done, the wear is from wear-in of new parts and the silicon is from harmless silicone sealers used during assembly. If not, the excess wear is from brass/bronze parts and bearings. Silicon could show abrasive dirt, so check your air filtration system for leaks. The oil's TBN was 2.6, showing some active addictive remaining in the oil. 1.0 is a low TBN.

The car is driven 80% city and 20% highway. Judging from this report it doesn't seem like a good one. Copper and lead seems way to high and not sure why. With a TBN of 2.6 after 4k miles it seems like I need to change my oil every 5k miles.
