No problems at all.

I've got my 5000mile oil sample, I just need to get it to the lab. I'll see about doing that on monday.

Finally got the sample results. It took so long because of a mail error.

FI,

Reportedly this system filters to a tenth of a micron:

It is obviously a little pricier than your set-up, but I was very interested in the idea of not having to pay for replacing filters

I have a line on an old lab centrifuge, but it is 220V

The main problems with those are they take up alot more space than a by-pass filter, must be mounted flat, require an unrestricted gravity return to the oil sump and they need more oil to work than a bypass filter.

Other than that, they filter much more efficiently than any paper filter ever could and pays for itself with no filters.

So did the 5,000 mile OA allow you to continue with the same oil to 8,000-10,000 miles?
I used the turbo diesel truck Mobil synthetic on my last oil change and plan on an analysis at 6,000 miles. In my truck I used the Amsoil 15w-40 with an EA Amsoil filter. I plan on doing an OA on that one at 6,000 as well. Who did you use for the OA?

What is your opinion on the level of soot in the oil when using B99 compared to petroleum diesel?

I've only got 3000miles on this oil sample so I'm going to resample again at 6000miles. I used Titan Oil, a local company.

Soot is 0.8% on the current synthetic oil at 3000 miles vs 0.4% at 3000 miles on the dino oil when I changed it.

What did the analysis say about when you should change it? I can't read that thing very well.

Sorry, I don't have a scanner. I'll see about getting one tomorrow.

It says "Values normal for this sample. Resample at normal interval."

My latest oil sample with 6000miles on Delvac1. All is good so far.

My next sample will be at 8,000 miles, about as far as I'll take it no matter what the results show.

(Sorry about the quality. I still don't have a scanner and their printer's ink is very light.)

I decided to go ahead and change the oil today. No particular reason other than its a beautiful day and cold weather will be here soon.

In total I went 6 days shy of a year and 7,253miles on the oil. The by-pass filter still gets hot so that means its still filtering and flowing oil.

So how much better does it filter than with the MB stock setup, I couldn't tell if there was a significant change in the numbers.

I have been going about 5-5.5k per change on delvac, but will be switching to Rotella Syn soon due to it being cheaper....I will probably go about the same miles on that oil as well.

What do you usually pay for an analysis. Blackstone is $22 and thats pretty steep, may as well spend it on a filter/some oil instead.


I am using the Turkish FRAM filters in our MB's now....with the wound cotton string inside the cartridge. Anyone have any results to show they filter any better? They seem to be made stronger and also don't have flakes of cotton gin debris falling off of them when taken from the package, so that is one of the main reasons I switched.

It hasn't filtered out all the soot, but it has kept it under control. It's mainly to get the sub-10micron abrasives out of the oil.

I got a bunch of really old prepaid bottles from one of my past jobs. I have no clue how much they cost but free is free and I have a few left.
It isn't as detailed or informative as Blackstone's services but it's given me the confidence to say that 6-8K miles with synthetic oil is safe for a 617.

Do you think 6-8k is safe even with the stock filtration setup and good (FRAM) filters? Or is the auxillary bypass necessary to keep the soot down.

I know that on our 300D, we put it on Rotella Synthetic, and after over 600 miles the oil is still light enough to see the dipstick through the oil on the stick! I have never seen this before, all the dino oils I used to use, as well as the Mobil 1 Turbo Diesel Truck, have all been jet black after a few miles or less. The Rotella has "Advanced Soot Control", maybe they really mean it!

I believe so. The bypass filter can probably let it go longer, but I'm not personally comfortable taking the oil beyond 8,000miles on any passenger car engine.

IIRC, and I have to look at some older results, the OM617 engines loaded about 0.7% soot per 5000 miles.

The 606 or whatever the NA 3.0L 6-cyl used in the w210 is does about half that.

We are doing >10k mi OCIs on the E300D, and I would be very comfortable doing 7500-10k OCIs on a 617.

Will have to see on this 616... I think Ill ru schaeffer's 9000 5w-40.
