Oil Filter Company Babble, Purolator for 617
Still trying to get Info on Oil Filters.
Original Letter sent to Purolator: Hi I am the owner of a 84 Mercedes 300D. I recently purchased one of your L43056 cartridge type filters. This single filter has two filtration sections to it. The lower Full Flow section is made of pelted cellulose media and the larger upper Bypass filter section of the filter is filled with un-refined cotton (cotton +parts of the cotton plant). The Oil that goes through the upper bypass section of the filter goes back to the Oil Sump after it is filtered and is not to be confused with the Bypass Valve that is in Spin-on type Oil filters; on Mercedes the Aluminum Oil Filter Housing itself has the Bypass Valve built in to it. What I would like to know is the Nominal Micron Filtration of both the Full Flow section of the filter and the upper Bypass section of the Filter; or if you prefer the Beta Rating of the same sections? Response From Purolator Peter, We at Purolator received a letter from you requesting some information about nominal micron ratings for the L43056 filter which we supply for Mercedes applications. This filter is one that we purchase from a supplier in India, so it is not manufactured by Purolator. I have contacted the supplier to get as much information as I can about the filter. Please read the email sent to me below: Travis, As per Engg details avbl - the Full Flow part consists of cotton stuffing, and its not possible to generate the pore size for this part. The By-Pass part consists of cellulose media with a meanpore size of around 35 microns, Kind Regards Sharad Bhatia As described here, the full flow part is the part that consists of the cotton stuffing. This is the high efficient portion of the filter. I would say a max of 15-20% of your flow occurs in this section. The bypass section is the section which consists of the cellulose media and has a mean pore size of 35 micron. Mean pore can be stated to be the 50% efficiency rating size and thus may be called the nominal micron rating for this section of the filter. Feel free to contact me directly if you have any other questions. Thank you. Travis Canup Design / Development Engineer Purolator Filters NA, LLC --------------------------------------- 3200 Natal Rd Fayetteville, NC 28306 910-426-4817 travis.canup@pureoil.com My response to the Purolator Info: Thank you for your response. However, your answer is very confusing an inaccurate. The Full Flow (smaller) part of the filter is made of the Cellulose (paper) filter Media. And, it is the (larger) Bypass section of the filter that is filled with the "Coton Stuffing". Because of the above I do not know which section of the filter you are saying has the 35 microns Purolator response: You are correct. The supplier was wrong on this. I had the same question myself. The full flow section has the 35 micron media and the higher efficient portion (with cotton stuffing) is at the top portion of the filter. Sorry for the confusion. Travis Canup Design / Development Engineer Purolator Filters NA, LLC --------------------------------------- 3200 Natal Rd Fayetteville, NC 28306 910-426-4817 travis.canup@pureoil.com Other comments: To me 35 Nominal Mircon full flow section is not good filtration to me. I saw an STP Oil Filter at the local Atozone (no bargin at $10) Purolator (at least it was only $7) and the STP filter for the 617.95s appear to be made by the same company. The color of the box and even the wording of the text were similar. I again Emailed them asking for the Microns of filtration for the Bypass section that they never answered clearly.

Ether way, 35 microns is high and "cotton stuffing" isn't going to filter anything.

I picked up the sample Purolator Oil Filter L43056 from Pep Boys at now that I am thinking about it I believe was $6. It has made in India printed on it and neither the outside or inside (I cut it open) look like the Mahnn filter. The STP I saw at Autozone had the Made in India ink stamped on the metal of the Full Flow end and othewise looked like a twin of the Purolator one. I guess they changed their supplier. Always a good idea to open the Box and take a look at what you are getting.

Thanks for catching that; I added the word "not" to the good filtration.

I would be interested to know how the Mann filter stacks up to the Purolator too.

Interesting.....
I just looked at a Mann filter I have in the garage. PN 1055/1x. It is made in Czech Republic. I remember reading thorough an oil thread here... Or was it a fuel filter thread? I cannot remember? But, there is definitely a difference in the filters. I have a Cummins and CAT dealer near by. I'm curious if they would have anything to offer in the way of Donaldson or anything else. Maybe even a bypass setup with a CAT or Cummins (Fleetguard Stratopore) filter? I'm a little new to the Mercedes. So, I'm still learning all this crap. The reason I went with Mann is because of all the labels under the hood. Hopefully it is a good decision. There are some bad filters out there... I have seen them and I have seen the elements fall apart and get into the oil gallery. Not pretty $$$.

Ive been using Mahle filters in mine. Anyone have any input on Mahle's?
Mahle is what we use at work (BMW shop) and their filters are alot better in appearance than the OEM BMW filters that iirc are from Mann. The OEM ones have a foam/epoxy injected media endcaps that just fit "snug" over the core posts. The Mahle's have a plastic endcaps that have actual o-rings to seal them. The originals have a bad habit of the media breaking/crushing and not the Mahle's. Also most of the Mahle's have Knecht and or Tecafilters on them.

After reading a couple threads here about oil filters and what is/is not inside of them, I have decided to use Wix, which can be purchased as a Napa Gold. I have noticed that the construction is different than the Mann, as it does not seem to have a bypass section.

Thats excactly what I use, but I also have an Amsoil EaBP90 bypass filter installed.

The Wix use to be a two section filter like the Mann. then a few years ago they went to the one piece filter. I figured they were cutting production costs.
I use the Amsoil BP-100 with the EAO-26 and the Mann filter. soon as my other 2 are used I`ll go with the Wix. think Baldwin was the other good one. Charlie
