I have never done UOA's. Going to do one on our new car.

I seem to remember reading on here that Polaris, Horizon has better testing for one aspect of UOA's than Blackstone. 

I'm concerned about oil dilution but want the most accurate tests of course. 

Which one?

I like Dyson. You get a percentage of fuel instead of a pass/fail flash cup test. 

 

Terry sends you a printed file AND and audio file and will field questions till the cows come home.

 

BlackSilverado (Nick) pointed me in that direction.

No. The URL I thought belonged to his site says the domain is not connected. Maybe a temporary glitch? Black02silverado should have something for you. I've sent him a PM

 

It was dysonanalysis.com as I remember

Hey guys, sorry to get back on here late.  Been busy fixing things around the house.  I installed a pocket door. I must say, it wasn't hard but I'm no drywall guy.:crackup:

 

Terry is retired Navy and also just retired from his Analysis business but told me that he is doing some still, just not on the scale with corporations and such.  You can reach him at  [email protected]

 

Like stated above by Grumpy Bear, Terry sends a PDF and an audio file to explain the UOA report.  Also his test for fuel dilution is current and more precise. It is my understanding Blackstone Labs uses an older method and it isn't very accurate.  The process to detect fuel is expensive for the current system and one can't blame any lab for not wanting to update their equipment.  Fuel dilution is important now with direct injection.  It can cause major issues.  Case in point.  My FD in our 2016 Suburban was 3.7 and that is way to high.  Needless to say it caused issues and this is why I do UOA's.  So I can adjust my drain intervals accordingly.

So is Blackstone good enough? Sounds like it to me.

They are for the most part.  Most don't go extended like me.  Oil Analyzers/Polaris Labs uses an updated method FTIR, so it would give a better view on how your oil is doing.  There are oil UOA's online where someone sent a sample to each lab and Blackstone's flash test showed fuel dilution as 0 but OAI showed it high.

Thanks Black02Silverado.

I checked out Polaris Labs. Their site isn't as easy to use. Blackstone makes it easy to get the sample kits.

My original post brought up the difference between the 2. 

 

just not the details.
