Blackstone comments: This the best report we'v seen so far for your Toyota. It's a bit unclear what caused the high iron last time, but that's in the past. High copper is in the past as well, and this engine matches up just fine with universal averages. As a reminder, universal averages show typical wear levels for this type of engine after about 5,900 miles on the oil. The TBN is 3.3, showing active additive left for a longer oil run next time and with wear looking this good you might as well. No fuel or coolant showed up and air and oil filtration are fine. Try 12,000 miles next and check back.

Oil was in for 5 months and I used a Mobil 1 oil filter. Refilled with Pennzoil Ultra.
I pulled a sample due to switching to the M1 TDT to see how it held up (never ran it before). The iron, copper, and lead are the lowest numbers I've seen.
