I have not. I assume they wouldn't give out anything, but I could ask. Good idea.

What more are you looking for besides your data, average data for the engine and oil change interval, and commentary based on your data?

A few things:
1. Data specific to the 2UZ by mileage. Blackstone provides universal averages. That includes brand new 2UZ and those with 500k. IMO, it's more valuable to know if any trends exist as a function of mileage.
2. Data from various oil weights and brands.
3. Data from the 2UZ in relation to change intervals.
4. Data from an imminent (sp?) failure. I would find it really interesting if we had reports prior to and/or during an engine failure.
5. Overall recommended change intervals.
6. Uncovering some other trend. I spend my day job pouring over measurement data sets. It's enjoyable to spend some of that mental horsepower exploring something that's a hobby and not industrial measurements for oil and gas.

So, the raw data dump related to the 2UZ engine. It sounds like it may be a possibility if they can offer it in database form without customer-specific information. If that isn't easily created, then ..... best of luck.
1. Damage/Neglect: none
2. Motor Oil/Filter: Mobil1 5w30 w/ Toyota Filter
3. Change interval: Filter change at 2k. Oil change at 4K
198k miles
Not sure what I was hoping for from this analysis. The only comment they made was some higher levels of Aluminum and Iron. May be due to the "clank clank clank" metal on metal noise I hear for a few revolutions upon start up.

Nah I didn't add anything, that is our engine oil capacity and this was done at the time of an oil change. Maybe I misinterpreted what I was supposed to fill in that column, whoops.
Mine on a 2006 LC with 165k. Just purchased it when i sent the oil for testing. Just wanted a starting point for future ref.

Yeah, they phrase it kinda weird. The intent of that field is "How much oil did you have to add to keep your oil level consistent during this oil change interval?" The answer for most of us is 0.0, which is pretty unusual for high mileage vehicles, but it helps that these are low stress engines. Relatively low specific output.

Got my AHC results back! LOTS of iron! I'm really interested to get the next test back and see how this does over time. The system works well so I'm not really concerned, but I'm thinking this may be a sign of pump wear. The fluid was over 40k miles old, so definitely due for change.
*Also note: Look at the universal averages for silicon. I wonder if the Toyota AHC fluid has silicon and my old fluid did not - potentially because the wrong fluid was used. The fluid I pulled out was not pink at all. Straw yellow. Interesting....

You should sent them some unused OEM fluid to get your baseline

Yup, my thoughts exactly. I'll ask them if they have a baseline already for unused fluid. If not, I'll send one in to get it.

If they don't have virgin sample data to share, set up a GoFundMe or equivalent thru your website to pay for the analysis. I'll donate $1 without hesitation.
Another 500K + data point for you. Pretty happy with this. Obviously they goofed on the QTS added part, should say like .5 instead.

Awesome, thank you. I've updated my database. It's very cool to see so many miles. Much appreciated!
Just got my report back. When I changed the tstat(installed backwards) the truck temps had got up to ~220, but was only operated for a few minutes prior to reaching this temp then shut off. I mentioned it on the report to them to put them on guard. I felt good reading the report!

Here are some updated summaries.
A few takeaways for me so far:
1. Mileage on engine is a poor predictor of wear indications.
2. Lead wear is often so low they can't measure it.
3. Iron wear per mile seems to be consistent, regardless of mileage on oil.
4. Lead wear per mile shows a trend (albeit weak) of increasing wear per mile as the oil age grows.
Keep em coming!
