Bought vehicle used, added 2QT of Castrol Edge Extended Performance 5W30 (gold bottle), this is the oil I used when I had the oil changed too. Will try to get another analysis done at 3,000 miles.
Blackstone Labs comments:
Maybe this engine had some work done to it before you bought it -- wear metals and silicon are
elevated compared to averages, and wear-in from recent work would be a nice explanation. Otherwise,
maybe the silicon is from abrasive dirt and it's causing piston wear (aluminum) and steel wear (iron).
Brass/bronze wear (copper) isn't typically affected by dirt. Check the air filter for leaks or issues. Universal
averages show typical wear levels for this engine type after ~5,200 miles on the oil. The viscosity is in the
5W/30 range, and the TBN was fine, but try 3,000 miles to monitor.
