Just got my Blackstone Laboratories report on my engine oil:
"What a nice Audi engine! As you can see from the Universal Averages (which are based on an oil run of about 5,800 miles), these engines tend to wear very nicely, and yours is no exception.
Insolubles (oil oxidation due to heat, use, and blow-by) were low at 0.3%, showing good oil filtration and complete combustion.
No fuel dilution or anti-freeze was present in the oil.
The TBN was strong at 5.1 showing lots of active additive left in the oil. 1.0 or less is a problem.
We think this engine is doing great at 133,000 miles. Try 8,000 miles for your next oil change interval."
NOTE: I was running Mobil 1 5W-40 and an OEM oil filter. I only added 1 qt. over the 6,000 miles this oil change was in my car.
- Not bad. Unfortunately M1 5W-40 is no longer available so I am running 5W-40 Castrol Sythetic now. I will likely re-do this test in a few months to see how the Castrol holds up.
- All elements were at or below the Universal Averages (UA) except for:
IRON: UA = 5 ...... My Car = 8
MLYBDENUM: UA = 2 ...... My Car = 46
NICKEL: UA = 0 ...... My Car = 1
BORON: UA = 33 ...... My Car = 40
SODIUM: UA = 0 ..... My Car = 12

moly and boron are additives, so no worries there...
I'm curious about sodium though. Sometimes it can indicate coolant leak. But if Blackstone didn't mention it, I guess it's not enough to indicate a problem.

Cool.....thanks for the insight.
I'll keep an eye on my coolant level. I did just top it off with a few ounces but that is over a year period that it's been in the car. I should be changing it out soon.

I got my back a few weeks ago. The whole thing is pretty cool
He told me to change my plugs and air filter. I'm going to try that and send it back.
The car has 163k miles on it. Tracked for 2 days with this M1 0W-40

that's just the standard oil test. if you want the TBN done, which you should, that's $10. also,
if you want Dyson's personal analysis, that's another $10.
But, if you pre-pay for your $20 sample kits, let's say a 6-pack, they'll be $3 off.
so, you could pay $37 for the Dyson Analysis of your oil with a TBN test.
It used to be only $30 total for the DA. I guess he wants more money for his outside services from Blackstone.<ul><li><a href="http://www.blackstone-labs.com/dyson_analysis.html">http://www.blackstone-labs.com/dyson_analysis.html</a</li></ul>
