Great report - nice to see someone fully utilize a high quality lube. Silicon looks fine for a 16k run. Thanks for posting.

For what it's worth, I have a 2006 Tundra with the same engine.

In addition, I have owned about 10 other Toyota vehicles, and have performed UOAs on all of them long term.

Toyota uses Silicon sealers in its engines. It generally takes a long time (well over 50K miles) for the silicon levels to completely wash out and not contribute significantly to silicon levels in normal OCIs. However, Silicon that leaches out from sealers can accumulate in extended OCIs, and I suspect we're seeing some of that in this silicon level.

Impressive results for 16k. M1EP is a great oil.

The fact that it stayed dead-in-grade impresses me the most.

That's a home-run of UOA's. Couldn't imagine a more flawless performance.

Yup.. M1 is my synthetic of choice
QSUD may come in as my second choice..
Check To See That The Oil Jugs You Buy Have The Exact Amount Of Oil In Them And Have An Inner Seal Under The Cap. I Use Mobil 1 And Fram Ultra Filters

a TBN below 3 is not good. see page here Click here>>:

Read the last example...

The fastest production car in the world had a team of engineers determine Castrol Edge is the best oil in the world.

The proof is in the car. the koenigsegg. the engine and it's records speak volumes. it is what it is. it ain't marketing.

Why are we going for such long OCI anyhow ?

Wallyworld + do it yourself = $$Profit$$ wink

What is wrong with pennzoil high mileage it has WAY more Boron and Moly than mobile 1 and is $15 @ 5 Qt. at WW ?

Even quaker state HM or ultimate would be better really.... Merry Xmas all cool

While most of what was said here is badly worded/phrases/expressed... there is ONE thing that I see worth elaborating on. To say a "TBN of less than 3 is automatically bad -or- more than 12mo is bad" is not appropriate, but the two do have one thing in common... these extended drain/interval UOAs also should have the TAN tested. Once the TAN gets above the TBN - it means the detergents aren't able to fully neutralize the acids and there becomes concern surrounding corrosion protection. This wouldn't necessarily show up on a UOA either. I think that's where he was going with those two statements (albeit very poorly). Not defending him, but I'm personally always curious to see the TAN along with the TBN on an engine after a drain interval like this. Mobil 1 oils tend to have a naturally higher TAN than other oils anyway... just worth noting. My personal preference is to change the oil as the TBN/TAN cross over each other. In my wife's V6 fusion running Pennzoil Ultra Plat - that's right around 7,500mi (UOA confirmed).
