"You happen to be driving a car with one of the best wearing engines ever made under the
hood. If the type of driving you do is not a problem (and so far it doesn't seem to be), then extending your oil
use intervals up to 10,000 miles or beyond is perfectly feasible. Universal averages for this type Honda are
based on 172 samples that have averaged 5400 miles on the oil. The TBN read 4.8, still strong, so this type
oil is good for a longer run. Try 9000 miles for the next sample. Air and oil filtration are excellent and no
contaminants were found. Great engine!"
08 Subaru Legacy
Driving style: Middling. My wife's daily driver. She drives 70 miles a day, so it gets plenty of cruising at speed. Almost all backroads and highways. Occasionally burst of WOT to 4000-5000 rpms, rarely to full redline.
Oil: Pennzoil Platinum 5w30, 3600 miles on it, no make-up added and no consumption noted.
Filtering: PureOne PL14610 oil filter (about 20% taller than the recommended PL14612 filter, but with the same exact specs).
AVO Dry Panel Air Filter cleaned at 9k, seems to be working fairly.
Blackstone Comments: JOSEPH: In this initial analysis copper was the only metal out of line. It comes from brass or bronze parts.
It doesn't necessarily read at a problem level here, but does show some excess wear at corresponding components. Other metals were okay, so we'll monitor copper closely next time. The viscosity was 5W/30,and no gas, moisture, or coolant was found. Low insolubles show good oil filtration and no combustion
issues. Low silicon shows good air filtration. Hopefully copper will drop next time. It may be left over from when the engine was new.

Toyota Tundra 4.7:
Probably 70% highway driving, 30% stop-n-go traffic.
Time in use ~6 months
Overall pretty pleased. Intend to try to reduce the Si. I thought I had already done so.
Blackstone comments:It's been quite a while since we've seen a sample from your Tundra and wear looks as good as ever! You ran this oil considerably longer than the last that we saw but wear remained pretty low. With wear looking as good as this, we doubt that you'd have a problem going 10,000 miles on the oil if you wanted. No harmful contaminants were found in the sample and the viscosity of the oil read normally. At 80,000 miles we have no problems to report. It looks like you've been taking very good care of this one!

04 Honda Civic:
GREG: Heat, humidity, salt air, short trips...sounds like the makings of poor wear, but your Honda isactually looking great. It's handing the environment well, and most metals read right around averages. Theonly thing higher was lead, and this could easily be from a particle streak through the bearings. If so, it willdrop next time. The TBN read 4.3, which is still a strong reading. The oil was in good shape physically,
containing no moisture, fuel, or signs of coolant. The air and oil filters are working well too (see silicon andinsolubles). Nice Civic. Try 5500 miles next time.

EDIT: Finally found one for Rotella 5W40, in a Subaru engine:
Here is a good compilation of several UOAs of different oils in the same engine (Motorcraft, Syntec, PP and Mobil Clean):
