I'm quite amazed that MB sells filters with a good tablespoon or better of pure dirt in them, instead of forcing the makers to copy Turkish Frams, which I understand to be the original design.
Has anybody written MB and enclosed the pictures this site has generated? I wonder if they know what is really going on. I find it astonishing that a company that built its reputation on fine engineering could let such a practice continue. There's no Pep Boys close, so I use Wix. At least I know I'm not dumping dirt into the engine. During one of the first oil changes I did with my 240D, I replaced the little o-rings on the filter housing shaft, and was obeying instructions read on this site for blowing out that shaft with compressed air. Sticking out of the top hole in the shaft was a tail of cotton fibers - maybe .75" long when I pulled it out. That's for those who think the junk in those bypass sections stays there & it's OK to use them because MB says it is. That's when I changed to Wix. |

I'd stick with the Turkish Fram if you can find them. My buddy and I just recently changed oil on his 617 and we pulled out a Mahle Filter. After reading this I decided to open up the Mahle. Twigs, bugs, seeds and dirt! In case your wondering, the other filter in the first pic is a Mann Volkswagon 2.0 TDI Filter

I think it would be awesome if Roy or Phil could source the Turkish Fram filters and sell those here on fastlane along with the others...even if they carried a slight price premium over the ones featuring Twig n' Dirt technology.
I'd buy them....is it possible to source those? I luckily do have a Pep Boys within reasonable range....but not everyone does....especially since they closed some stores recently. (Including one 3 miles from my house ) I think I will head out to the one further away from here soon and see if I can clear the shelves of some more Frams.....I am going to start building an inventory so I can have as many as possible for the future. They usually carry 4 at a time....maybe I could get them to order in more....like 8 or 10 or something.

Great Pictures. Guess in about 3K Miles I'll open mine and post them.

I especially like picture #3, notice the cotton is just sitting in there. No compaction, no uniformity and no way to force the oil through it.

What is inside the MB factory by-pass filter section?
I guess I'm having a hard time with Fram being the higher quality filter, because I associate Fram with Kragens. I found 2 Turkish Frams and agree, that these are a better media. How is their orings fit into canister... snug or loose?

Lets set up a poll on "what filter would you buy if the price and availability where all equal".

Oil analysis results
I've been running an STP oil filter on an unmodified engine along with Shell Rotella T Synthetic 5w40 oil. This oil analysis was done with 4900 miles on the oil and it's still going strong with low levels of dirt (insolubles 0.3%). If you notice I've added 3 quarts of oil in that 4900 miles so you could make a good argument that some amount of contaminants are leaving with the oil. The odometer was non-functional on the vehicle when I got it so the indicated mileage is short by some unknown amount. For a 25 year old diesel with close to 200,000 miles to have oil that clean I couldn't be happier with the stock oil filter design. It's almost like the engineers at Mercedes Benz knew what they were doing.

With respect, look at the number of high-mileage MBs out there whose owners did not abstain from using cotton waste filters and try and tell me those engines are suffering.

Yes, in the picture it appears that both top and bottom are pleated paper elements:
http://catalog.baldwinfilter.com/ When I Emailed Baldwin Filters concerning the Micron Ratings they Claimed: the Full Flow (small lower) section to be 18microns and the by-pass at 15 microns. However at the time I ask the question I had not looked into the rating systems of oil filters. If these are "Nominal" ratings it means that they filter out %50 percent of that size or larger particles. As best as I can tell from what I have learned this would be a Beta (or the greek letter B)18 micron=2 for the Full Flow part and a Beta(B)15 micron =2 with the "2" reresenting the %50. It could also be listed as a Beta Ratio 18/15=2/2 An "Absolute" rating, as an example I will use a Absolute 5 micron filter is listed as Beta(B)5microns=200 with the 200 representing it filtering 99.5% of the 5 micron particles or larger. "Absolute" rated filters are suposed to have a Beta rating of 200. Here are some filter cross referance sites. Some of them will tell you the filters Beta, Nominal or Beta Ratio. http://www.wixfilters.com/filterlookup/index.asp http://www.filtermart.com/fpdbdb/fmccross.asp http://catalog.baldwinfilter.com/

I randomly picked different makes diesel fuel and filter part numbers from filters that are selling on Ebay. After running them through the Wix filter cross referance I found the most seconday fuel filters are in the Nominal 10 micron range a few were awful up there in there above. CAT and some of the PU trucks with cummings engines have fuel filters around 2 micrions. here are some sites with filter interchanges: http://www.wixfilters.com/filterlookup/index.asp http://www.filtermart.com/fpdbdb/fmccross.asp http://catalog.baldwinfilter.com/

I have nothing plugged off in any part of my lubricating system.p>Later I did install a by-pass filter and I did drill through the center of the fuel filter cap and tap the oil from there that would normally go into the crankcase. Even then I did not not have to plug off the stem to divert the oil as there is a check valve in the stem that has a strong enough spring in it I did not have to plug it off to get the oil to go to the by- pass filter. I added this later: I did not realize that this was an old thread!!!!
