Used Oil Analysis on 2UZ-FE

[ELLTEE]

Just got my first UOA from Blackstone Labs. I pushed the oil change interval out to 8,800 miles for the first analysis to set a baseline. It's a good result, although I'll probably change this oil at about 6000 miles and do another UOA to check the iron levels.
The oil is Mobil 1 5W/30

Aluminum 4
Chromium 0
Iron 16
Copper 2
Lead 4
Tin 0
Molybdenum 52
Nickel 0
Manganese 0
Silver 0
Titanium 0
Potassium 2
Boron 88
Silicon 13
Sodium 4
Calcium 2343
Magnesium 13
Phosphorus 558
Zinc 627
Barium 0
SUS Viscosity at 210 deg. F 62.5
Flashpoint deg. F 380
Fuel % <0.5
Antifreeze % 0.0
Water % 0.0
Insolubles % 0.5
TBN 3.0

Miles on oil: 8800
Time on oil: 8 months
Milage at sample: 68,000
Filter: Toyota
Oil added: 0 quarts

Blackstone's Comments:
Iron is a metal that tends to track with miles of use. You've run this oil almost 9000 miles, and we think that's probably why iron reads high. The other metals read around average levels so we see nothing in this used engine oil sample that would point to any kind of problem. This oil type is working well for your engine so we suggest staying with it. We found no gas, moisture or signs of any coolant in the oil. The TBN was 3.0, so the oil had active additive left in it. Check back to monitor.



Is anybody else runing extended oil change intervals in their 100 series? If you've got an analysis, post it so i can see how other engines are tracking.

Here's one from a while back:

I just sent off for my kit. It will be interesting with 135,000 miles, 18,000 of which has been on Amsoil.

Apparently because you're such a nice guy and we're a bunch of imbeciles!

Thanks, Hank. I saw that one when Tab posted it, and I also saw it when E-ticket added it to the FAQ. (don't get all wadded up, there, Mr. Moderator!)
I'm looking forward to seeing a few more analyses posted, since folks on this board tend to recognize a good idea when they see one (i.e., the HIR low-beam light bulbs back a year ago).

Looks good overall to me LT. Here's my observation; on the extended interval you ran as I did with no filter change at the midway point. I would be curious to see your results with the Mobil1 filter at a similar interval. That is the only difference in the comparison of our UOA's. I realize that no 2 engines are the same and there could be that much variance between 2 samples with identical setups but that may or may not have an effect on your iron. It's still not a bad number though. Mr. T makes a good filter so it may not have any effect!

You might check here www.bobistheoilguy.com they have a few UOA on this engine. The consenus on this oil site is that the Toyota/Lexus 4.7 V8 is real ease on oil. Just a great engine. But you guys already know that
