2004 Toyota Sequoia 4.7L V8 2UZ-FE 111,981 miles.
20,979 miles OCI.
Mobil 1 5W-30 EP.
Donaldson P169071 oil filter with external filter magnet.
New Toyota air filter installed at 92,133 miles.
After my last OCI of 15,708 miles, decided to push this one a little further.
Oil in service for 13 months of local New England driving - mostly short trips of 5 to 20 miles plus some road trips and infrequent towing of 3,500 to 4,500 lbs trailer.
2-1/4 quarts of oil added in 20,979 miles. 1 quart added after 5,307 miles. 3/4 quart added after 14,947 miles. 1/2 quart added after 18,929 miles. Original fill was intentionally low to allow later oil addition to refresh the additive pack, so oil usage over OCI was actually about 1-1/4 quarts.
Filter cut open. Nothing visible in filter pleats, can clean and small pinch of dust-like ferrous particles visible at magnet location.

Blackstone Comments:
You ran this oil fill out to 20,979 miles in your Sequoia, and the engine barely even noticed! Iron tracks with oil use, so the 16-ppm found in this sample is a normal level and not a cause for concern. The viscosity was a bit high for a 5W/30 oil, but with wear at these good levels, we can’t complain. No coolant or fuel was found in the oil. The TBN at 3.3 shows some active additive remaining for a longer run. Try 22,000 miles on the next fill and then send in another sample to monitor wear. You have a great-wearing Toyota engine at 111,981 miles.
