Just got back the sample. What do you guys think

Blackstone has been demonstrated to be off on viscosity measurements as well as fuel dilution and spectrographic results.

It's to the point where I'm not sure why people bother with them anymore. You're paying for something (and then posting it for everyone to see) when you cannot trust the results.

That's what this guy thinks.

Probably my last deal with BlackStone I’ve ordered a kit from Speed Diagnostic to retest

I think, judging by many of the posts here, and my personal experience, that you are correct. I have got mixed results from Blackstone. I am going to give Speed Diagnostics a shot.

Blackstone seems to be wrong, or IMO, wanting to much info from the user in their reports.

I have a promised, UOA on the Amsoil Synblend coming up soon.

I have personally seen low viscosities from them twice and the fuel dilution issue is obvious for everyone. Though, spectrographic results have been fine for me. But still, that's two strikes, which is enough and why I switched to OAI. Not to mention, OAI gives you oxidation and TBN for one price where BS charges extra for each.
 
I don't rely on anything the 'stoners report. Throwing darts at a board at the local pub is cheaper, and your chances of getting the 'right' numbers seems about the same.
 
Some do better than others. Mostly off target from what I see from these VOA.
Amsoil consistently over-performs. Blackstone has consistently under-performed for years. Regardless if it’s VOA or UOA, an Oil Analysis doesn’t give you one lick of valid data when attempting to determine how an oil will perform in a given application. It’s impossible for this kind of test to generate results. . Some do better than others when interpreting data. That’s what I see from this tea leaf reading.
 
Amsoil claims viscosity at 11.1 A little short on this test
How old is this oil? When was it purchased and how much dust was on the bottles?.... joking really!
Are you reading the most recent viscosity numbers at the Amsoil website?
The formulas / recipes change constantly.
 
Thank you very much for doing this, was curious about this oil.
It’s stronger than I thought it would be in the detergent department, but has less moly than I thought it would.
I agree the viscosity is probably off from what it should be.

I’ve sent another sample to Speed Diagnostic hopefully It will show better number
