This thread is for people who might be interested in comparing notes on UOA reports, specifically from Blackstone Labs (www.blackstone-labs.com). They offer free kits that they mail to you, and detailed instructions and packaging for taking samples and sending them back to the lab (USPS return shipping is only $1.90). It not expensive ($25 for the basic analysis and $10 more for additive analysis used in determining the practicality of extended usage of your oil) and gives a nice picture of engine health at a nice regular interval. I know there are a few of us that use the service and thought it might be nice to compare notes.

For starters, here is my report from my 12k mi oil change in early December 2010. It was a 3k mi usage interval and the oil was Castrol Syntec 5w30 full synthetic. Note that the "Universal Averages" are from Subaru 2.5L turbo (EJ25X) engines in my geographic region. Enjoy!

I may give this a go as well. Just hit 40K miles today with an oil change comming up in 2500 miles (3000 mile change). Also been using Rotella since around 15000 miles.

like i said, very interesting and thanks for posting your results. it'll be nice to have this be the comparo thread and hopefully get enough people involved to see how long some of these oils can perform to and under what conditions and geographic locations. i got 3500 miles on the oil in her now, ordered my kit yesterday and will post up when the results get here in about two weeks. thanks for starting us off!

Steve, do you know if blabbering ships to Canada to do those tests?
I read somewhere that Blackstone does receive samples from Canda, but the postal regs in Canada are obviously different so mailing might be an issue. If you're interested, I'd definitely recommend giving them a ring, as I have heard they have EXCELLENT customer service.

Thanks, for posting, Nate! Looks like we got pretty similar results. Nice to have some (at least isolated) validation. I wasn't sure if anyone else would post a report! ;D

BTW, check out the FAQ page if you have a minute and could use a laugh. At least a giggle. http://www.blackstone-labs.com/faq.php

No problem I plan on doing it again with a batch of Rotella next to compare the two.

I wonder why all of ours (mine included when I get it posted up) show significantly higher levels of molybdenum then the universal averages..?

I tried a thread like this a while ago but nobody contributed :(

Nice to see more people doing this now with our cars. The higher moly count can be due to comparing different oild (it's an anti-wear additive so some use more in their blend).

Found this site to be very informative for anyone to check out: http://www.calsci.com/motorcycleinfo/Oils1.html

Another component is emergency lubricants. This is typically zinc, phosphorous, and molybdenum. These chemicals are present in case your oil film completely breaks down, due to extreme temperatures or pressures. These chemicals are supposed to be a last resort defense against metal to metal contact in your engine. Oil companies are cutting back on zinc and phosphorous, as these metals are hard on your catalytic converters. They're substituting molybdenum disulfide, which lowers friction and improves gas mileage. It also causes problems for people with wet clutches, that is most motorcycles.
