Blackstone Oil Report Repository - Share Your 2UZ Reports

[suprarx7nut]

I've been testing my oil with Blackstone for a few years now and I'd love to start a master database with data from everyone else that has done the same. I know there have been a few reports posted in various threads, but I hope this serves as the "master thread".

Please include:

A screenshot of your PDF report table (crop or blur your personal info).
AND
1. Any notes on engine damage, motor neglect (starved of oil, overheated recently, smokes on start up, etc...)
2. Motor Oil Used. Brand, Type and Weight (IE Castrol Edge 0-40)
3. Your normal oil change interval (IE 6 months or 5,000 miles)

What I hope to gain: Trending contamination vs mileage for the 2UZ. Blackstone provides universal averages, but not averages for the 2UZ with respect to mileage. I believe there will be a long warning period where a 2UZ is nearing failure and this database may provide valuable insight as our vehicles rise in mileage and age and engine failures begin to creep into the community. I'll collect this data in a separate spreadsheet and create typical low/high limits based on some simple statistics.

Here's my first contribution from the Cypress LX Build. I'll also include my 99 in a subsequent post.

1. Damage/Neglect: none
2. Motor Oil/Filter: Castrol Edge 0-40, Toyota Filter
3. Change interval: 5k miles

One more thing to add: ATF, Diff, Transfer Case and AHC fluid can be tested as well. Please share any of those results you might have!

2000 Land Cruiser
1. Stalled while completely submerged approx. 70,000 miles ago. Engine removed, cleaned, dried, & reassembled. No damage
2. Mobil 1 Extended Performance 5W/30 w/ M1-102 filter
3. I try for 5k intervals but sometimes it ends up being 7,500; you can see my first sample was actually 10k

Here's my 99's last report.

1. Damage/Neglect: none
2. Motor Oil/Filter: Castrol Edge 0-40, K&N Filter
3. Change interval: 6-12k.

Interesting to note the higher levels of lead and iron, which tapered off after the first two tests. Also note that even on the 10,000 mile oil change interval the engine burned almost no oil. Impressive.

From my first change on my 07 at 130k. It’s at 145k and it’s time for another change so I’ll get it tested this time.
1. Damage/Neglect: none that I know of. Maybe a tiny head gasket leak when cold.
2. Motor Oil/Filter: 5w30, Toyota Filter
3. Change interval: 5k approx miles(4300)

2007 LC.

Second change since I purchased it.
1- No damage
2- M1 5W-30, Toyota filter
3- typically around 6k intervals (5k-7.5k)

Thank you for your contributions so far. Off to a great start. I'm anxious to see more high mileage tests!

Here's a sneak peak of some iron and lead vs mileage charts. Note the Y-axis is the quantity of the element per thousand miles on the oil. This helps normalize the tests for the various lengths of oil change interval.

Once we have more data I can break it up a little more and get fancy with some additional metrics. For now, iron (rotating assembly wear) and lead (bearing wear) are most interesting to me.

The lead and iron concerned me, too. Hopefully it falls off. One explanation might be that I didn't put a lot of miles on the oil over a long relatively long period of time and definitely do some mountain driving.

1- No damage
2- Amazon 5W-30 Synthetic, Toyota filter
3- 4,198 miles (9 months)

My iron was "high" too. I'll get my test posted in the AM.

AH! Great thread and graph work @suprarx7nut. Ill contribute what I can find on my computer. Looks I have two tests here for posts 500K and I'll have a third for you soon:

WOW! Score! Thank you for that. That's really, really cool. Your lead and iron levels are still low despite essentially DOUBLE the next highest mileage. It's really neat to see those report numbers, please keep us in the loop if you get more tests in the future!

 

[gregnash]

Here's mine from back in September-ish timeframe... Have moved to a 6500 mile interval, of which I still have another 2500 miles to go before the next oil change.

1. Damage/Neglect: none
2. Motor Oil/Filter: Kirkland Brand 5w30, Toyota Filter
3. Change interval: 5k miles (will be moving to 6500 per their instructions)

 

[Lonegrasshopper]

Ordered a kit, but it will be some time before reporting back in. I changed my oil 2 weeks ago, and my guess maybe March or April when I'll change it again. Not too much driving these days.

 

[Skidoo]

This test from 2008 may be one of the earlier tests you get. I bought my 2000 LC with 128K miles in 2008, so this was my second oil change.
Now have over 226K miles, so might be time for another test.

1. Damage/Neglect: none
2. Motor Oil/Filter: Valvoline 5-30 (dino oil) , Toyota filter
3. Change interval: 5-7k.

 

[gungriffin]

1999 Cruiser with 294k miles. Supercharged, 34s, 4.88s, about 7k lbs. Approx 1200 miles of the interval spent in low range. Truck is overgeared by about 8% right now so the mileage reads a little high.

1. Damage/Neglect: none
2. Motor Oil/Filter: Amsoil Select 5-30 , Toyota filter
3. Change interval: 8k

FYI your home address is now on the internets.

1. Damage/Neglect: none
2. Motor Oil/Filter: mobile 1, Toyota filter
3. Change interval: 10k

it already was! almost everyones is.

 

[Pahizzl]

Great idea...I’m an oil change reading enthusiast too.

1. Damage/Neglect: none
2. Motor Oil/Filter: Pennzoil Ultra Platinum 5W-30 / OEM Filter
3. Change interval: 8k miles (still waiting on my second 8k mile change before sending another sample.

 

[suprarx7nut]

Thanks all, this is awesome. Keep em coming! Getting enough to really hone in on typical figures and trends.

It seems my old 99LC is an outlier when it comes to lead. About 18 months prior to my first Blackstone report I had a lot of towing in the mountains with ~13k miles on a change. I wonder if that spiked lead wear. I was WOT for minutes at a time on a few occasions. I would also love to know what lead looks like on an engine with a failing bearing. My 99 spiked at 52 PPM at 265k, but numbers lowered after and it ran well 13k miles later at 278k. Presumably no impending failure there.

Average recommended change interval: 7,000 miles.
Average actual change interval: 6,500 miles.
Average Odometer: 227,000 miles.

Plotting Lead vs Iron. Lower left would be no contamination, upper right would be a lot. Lead is bearings, iron is steel (crankshaft, cams most notably)

Showing correlation to contamination concentration vs miles on change. Nearly no correlation on lead, some correlation on steel (iron). Over-simplified conclusion from that might be that steel wear occurs evenly and your filter doesn't catch all of it; and that mileage on the oil isn't a significant contributor to lead wear within the ranges tested here. Note the highest lead level is at 10k, but so is a 0 PPM test.

Excited to see more!

If I have lets say 10 for iron at 10k miles and see 5 for iron at 5k miles, isnt the wear exact the same and there is no benefit to changing the oil at 5k?
