Anyone who has a MB BlueTec Diesel should review the following article;

BlueTec Diesel Oil

That's why I use VW oil .

 

Which oil do you use?


Joseph~

 

I use Amsoil high-zinc oil. Can't use this unless the DPF is removed, otherwise it'll get plugged up.

 

I can't understand why Stephen's site keeps coming on several forums.
The guy is trolling about bluetecs and the only thing clear on the page is that he wants $200 "donation" for his specific opinion.
You can get actual experience posted on this forum for free.

 

Whatever you say, Krzy.

I'm sure you know more than someone who's owned/operated an indy MB shop forever and has 50 yrs experience under his belt. What is it you do for living again? Just curious...
Oh, and btw; I gave him $50.

 

I am semi-retired.
When I don't think good MB technician will ever leave dealership job with all the clean station, excelent pay and pack of benefits to struggle in his own shop.
Only person who run into trouble in his workplace would do something like that.
But beside generic statements. what exactly did you get for $50?
The linked article is waste of time IMHO.

 

FWIW....................................

kajtek1,

To reply to your question and comments;
"I can't understand why Stephen's site keeps coming on several forums."

I posted them, "Joseph~" on both forums.

I have no connection with Tom Stephen's or his site, no one is "trolling".

In my opinion the articles he published are of value, and am considering to retain/hire him as a consultant/pay for his advise/comment/ options,

Do you have an issue with this?

Regards

Joseph~

My real name, I do not use a moniker/pseudonym

 

507.00 flavour .

 

This article was linked much more than that.
When Stephen might have experience in repairing Bluetec engine, he has no education and no expertise in chemistry and it takes chemistry lab to come with experience about oils.
You just labeled the article wrong. It is all whining with not much technical value. ... at least till you send the $200

 

Looking at this with a clear head on my shoulders and NOT like a white knight, I believe the contributions that Kajtek has provided on all the forums has FAR outweighed those that Mr.Stephens has. I have no connection with Kajtek nor Mr. Stephen but I'll tell you, I'd like to treat Kajtek to a beer. His way of thinking is what distinguishes him from the rest of manginas.

As far as Mr. Stephen's content, I think he's correct about few things. Many thanks for sharing. I dont know the man personally. Kudos to him for making extra cash.

I don't think it's cool of you to throw the low jab below the belt at Kajtek. This is a common way these days women shame men. (But I don't particularly blame women as a whole but the feminazi system of N.America).

You can check Mr.Stephens web site with way back machine if you want to know the exact weight and oil brand that he feels is best for your diesel motor. Should you feel inclined to send him your hard earned money, go ahead.

 

Kajtek1, you know him personally, ......that "he has no education and no expertise in chemistry"?

We all have access to a "chemistry lab", Blackstone Laboratories.

I did not label the article, the topic, title of the article was by the author

Regards

Joseph~

 

Now you are trolling
For future you might make indication in the title that you quote an article.
Otherwise it all fall on you.

 

WOW!

So lemme get this straight.

You emigrated to the US from somewhere in Europe (I`m guessing post USSR bloc country). You came to the US where you, like others, could start a new & better life and DO WHATEVER YOU WANT.
You then proceed to criticise Stephen because he decided to start his own repair shop back in the 70`s-80`s and build a life for himself and his family. Just WOW!

You have way more experience in diesels than I could ever have, that much is clear. However, you`re also full of yourself. It`s a miracle you can walk through a doorway without damaging your ears. You`re condescending to anyone who doesn`t share or agree with your opinion. If I didn`t know better, I`d guess you were diabolis`wife or nice(r) little brother.
Before you answer, be forewarned;

- I`m the product of immigrants from Greece in the late 50`s looking for a better life, so I have no issue with immigration into N.A.
- My dad started his own HVAC & refrigeration company in 1966, which I took over and have operated since 1986
- Thanks to my silly dad, I`ve built a comfortable life for myself. I own a home here in Montreal and another in Cape Coral Florida. Without going into more detail, let`s just say I ain`t missin` for anything.
- While I know relatively little about diesels, I`ve got years of wrenching on gasoline engines under my belt. I`ve got a 505 502 Ramjet big block swap into a GMC Safari under my belt. Took her on a tour through the USA on my way to Florida back in `05 without any issues. Bragging, yeah, but I just want you to know that you`re not addressing some computer geek who doesn`t know where the engine is in his vehicle.

To answer your question of what I got for $50, it was his opinion, over the phone, about MB and diesels, as well as his suggestion that I look into installing an oil filter adapter which allows the use of a spin-on filter.
If that $50 helps me get just 50k miles more out of my diesel, then I believe that ten dollars every 10000 miles is one of the best investments I ever made.

 

I did in my original posting, copy of posting;

"Anyone who has a MB BlueTec Diesel should review the following article;

So did you install additional filter? I would be very eager to read oil test result after?
I am in contact with some of buyers who bought MB from me and couple of them are way over 300k miles without any modification.
The only Bluetec I sold is at 200k and after replacing 1 injector runs perfect.
My present Bluetecs have between 135 and 260k miles, all running well on factory setup. (with 1 DPF delete, but that is emission stuff)
So I am always interested to find why other owners have troubles driving those cars.
...than... if other owners as mechanic for advice in chemistry, .... that might give partial explanation.....

 

Oil test result from Blackstone;

PETER: This report holds a surplus of good news for this MB. Metals are mostly low compared to
averages, and that squares with the km on the oil. For the OM642, our averages are based on ~15,600 km
of oil use. If you wanted to go that long between changes, the engine should be more than capable. The oil
held up nicely, based on the normal viscosity and 7.3 TBN. We don't consider the active additive to be used
up until the TBN is 1.0 or less. Harmful contamination was absent and the low insolubles point to effective
oil filtration and good combustion. Nice MB.

ALUMINUM 1
CHROMIUM 20
IRON 3
COPPER 0
LEAD 0
TIN 0
MOLYBDENUM 183
NICKEL 1
MANGANESE 0
SILVER 0
TITANIUM 0
POTASSIUM 1
BORON 197
SILICON 6
SODIUM 6
CALCIUM 1223
MAGNESIUM 830
PHOSPHORUS 770
ZINC 782
BARIUM 0


I noticed that the averages for the following were way lower/higher than my results.

IRON averages are 69, I'm guessing I'm good on this.

MOLYBDENUM averages are 35

BORON averages are 67

CALCIUM averages are 1848

MAGNESIUM averages are 162

 

Not knowing what oil it is and what was mileage on it - those numbers are worthless.?
Molybdenum at 35 average is for dino oils. Synthetics always have it much higher btw.
Silicon at 6 might indicate intake leak, but again - without mileage hard to make solid judgement.

 

I thought the oil mileage was in there. 3k miles. As I mentioned in the past, I'm sure the numbers are as good as they are due to that fact. I'm purposely holding off on my next oil change 'till I'm up higher in mileage, maybe 5k miles. Then I'll do another oil sample and post back

 

At low miles on oil and having no previous test to compare, it is hard to draw conclusion, but the metals in the oil are low, so if the additional oil filter does that, that would be good thing.
Than you have lot of sand "Silicon" in the oil, so regardless where it come from, why isn't the additional filter catching that?
You know that oil base doesn't wear and doesn't age in the engines? We do oil change becouse it is cheaper to change the oil, than install filters who would catch the fine contaminants and then replenish detergents and acids.
That is what they do on huge ship engines.- put big filtering system, do the test and keep adding detergents.
Looks like this is where the idea is going to.

 

What is used on large diesel engines are oil-cleaning centrifuge filters, the only cost effective method of ultra-fine particle removal. A centrifugal oil filtering system - can removes particles to .1 micron.

Some retailer cater to the "pickup truck market" using the "Model 25 Spinner II Oil Cleaning Centrifuges"

Revew attached PDF file.

Review video;


No one to my knowledge has put together a "kit" for the OM642, user can assemble there own.

Last time I look at a Spinner II Oil Cleaning Centrifuge model 25 cost for the filter was around $500.00 +- a few dollars.

The "centrifuge" description on the video is misleading.
I had real centrifuge filter on Fiat 126, who is old brother of Fiat 500 you might see in your neighborhood.
It was 2-cylinder 650 cc engine and consider "poor men car" . Nothing exciting about the car and nothing exciting about centrifuge filter.
So to make it clearer. - choosing oil filtering system is a compromise. You can always add more systems, run lab tests every 5k miles and shoot for making 2 million miles on the engine.
But most of the owners are satisfy with whatever engineers put in those cars and 1 million miles life expectancy.
We can whine about it all we want, justy like Stephen in his article.

 

It is clear.
