B/S LABS QUESTION?

So it would seem fuel dilution is a more prevalent problem than one might think?




That is what I'm thinking. I don't like B/S Labs method of calculating fuel dilution.

But with B/S- Something as simple as using the correct viscosity ranges can't be that difficult,




All the "should be" and UA are ...well, universal averages. If 900 UOA used a 60 weight ..and one used a 20 weight in the same engine, that "should be" would be way out of whack with what was in your engine if you were the lone 20 weight user. It gives you the mean average of all UOA performed.

They use flash point to determine fuel dilution.

Blackstone is fine for snap shots. As long as you're looking at the oil, you're fine. If you've got a problem, at least beyond something obvious like a screen door for an air filter, then Terry is surely the way to go.

Here's a blast from our past:

Four lab comparsion

As stated by others, to get a better level of detail, more accurately, it will cost you.

What's amazing is the super low silicon. How was that achieved?

Air Filter, first 15K miles Amsoil dual stage foam (cleaned at 10K of test)
- got paranoid due to perceived total lack of lip seal, and went back to stock Mann paper
- no difference in seat of pants output performance noted either way. Dirt numbers proved my paranoia
to be totally unfounded, but will stick with Mann paper, because BMW study showed great flow #'s,
fit is perfect and no sticky oil to deal with.


 
Gary - all well and good. But not exactly what I'm yapping about. Why can't B/S use the correct SAE J300 viscosity ranges, when they state the "should be" viscosity - so are you really stating the viscosity range for that type of oil is a mean? I don't believe it.
 
I'm under the impression that most b/s labs reports are useless for fuel dilution, which seems to be one of the most detrimental impacts on engine oil.

I cannot answer questions for Bklabs obviously, but I can interpret their data just fine.

You are all on target for the most part that their open cup flash testing may be too generous currently and recently I contacted Ryan with that concern.

Last year we began using a very critical Dyson lube formulating screen test battery for our Premium Service because Bklabs just cannot currently afford to install a FTIR setup. Nothing wrong with that just a fact. I must tell you that I am nearly giving away $250 of testing for the $50 Premium service charge and cannot sustain that with the personal in depth time spent on the interactive report. We are evaluating how to make this work before worst case completely dropping consumer level testing. You truly get what you pay for in automotive oil analysis.

I want to make it clear that I still use and trust Bklabs and continue to honor the co-op agreement for the Bklabs customers that purchase the Dyson package. If I see an issue with the test results I contact the lab and we investigate, I am not shy in getting it corrected. Ryan,Kristin,Jim, Adrianna,Billy are very sharp and honest in their dealings with BITOG'ers and have been long time supporters of this site before most of us even knew about the forum.

I think they can give the vis reading in cSt if requested so that should correct that concern.

They are still Dear Friends and Family to Me and BITOG so give them a chance to correct the issues.

Pablo, I agree the CTC derived Amsoil ICP tests are OK but interpretation is terrible and FTIR is useless. Another, "you get what you pay for" deal.

Until I can figure out how to keep it personal and interactive AND provide consistently good lab data the Dyson Premium is our flagship. Keeping it viable for the consumer is the current conundrum.

Cheers, Terry

Terry, if you eliminate TAN and TBN testing for those customers not interested in extended OCI, would this help keep the service affordable for the consumer?
 
I don't think TAN and TBN (critical for his analysis), which he gets from the lab that you send your sample to, is the problem. It's the amount of time that he has to spend on our analysis to keep it personal and useful for us, rather than cookie cutter and generic (all other labs). JMO though.
 
It would be a huge loss for many of us if Terry couldn't continue to serve us. His detailed analyses, quick responses to email questions, and direct answers to questions are something I wish I saw in all service folks that I deal with.
