Question Bypass oil filtration

Has anyone installed an amsoil bypass oil filter system on their cars? I'd love to hear about the installation and how it worked out - specifically how to get the metric adapter for the oil sending unit. Thanks in advance,
Dave

A Franz Unit

Brother of the Benz, Lightman
As a fifth year grad student at The General Motorts Institute, Flint Michigan my thesis was on lubricating oils and The Franz Filtration unit using 500 count double fold toilet tissue as a filter element.
Without going into a great deal of detail, The Franz process was at that time so far superior to anyother filterring methods that a number of the inplant rolling machines were converted and the oil never changed just the filter element.
I understand the Amsoil process is similar in that the filter is a celluious material.
One problem I could invision is the return drain line. In the past you used a sharp punch and knocked a hole in the oil pan and threaded a fitting into the convex hole.
With the M/B you would have to drill and tap.
As for the metric fitting, it is available at any parts house.
The Amsoil system could all be eliminate the gross changing of the oil; just refresh with 1 or more quarts every how many miles between filter changing.
I hope this helps and is of some encouragement to go further.

Yes the amsoil bypass system is similar to the toilet paper method you describe. The Gulfcoast system actually does incorporate toilet paper rolls or paper towel rolls as the filtration. The return line isn't a problem - theres a guy who will machine a fitting onto your drain plug so the fresh oil recirculates that way. The problem i'm having is how to find out what the exact size is, and where to get the adapter...? any ideas?

I'm interested in this as well. I'll be interested in hearing what you ultimately do. My father has a Ford F350 Diesel pickup that he wants me to install a bypass filter in. Got me thinking that I should think about it with my 300SD. I'm running AMSOIL in there now (just changed over), but haven't gone the bypass filter route yet. The car has just over 200K on it and I'm wondering if the payback is there for this on an older car.

It will be a simple install on the F350 - as you can most likely use the dual mount filtration set up from amsoil - the adapter should fit and there should be plenty of room to stash the unit. On the MB, the space can be a problem, as well as finding the proper adapters etc. I dont think either way will be a big deal technically. If you plan on keeping the car another 100k maybe you should go for it.

OK - it sounds like a good weekend project. I'll have to scope out the 300SD beforehand and do it first. (Practice on my own car.). When I got the MB, everyone told me the diesel engine should last 500K miles, so I figure I'm less than halfway there.

Pay-Back

Brothers of The Benz,
For those of us with high- miles engines, the pay-back isn't monitary but in what the superior filtration does to your engines.
As I said earlier my test on Tow Motor engines was quite astounding.
One engine had over 1500 engine hours and was typical with a sludgy crankcase and non-detergent oil.
A oil sample was taken and analysied.
The report was that the engine was in need of major rebuilding.
The Franz filter was installed, the oil WASNOT changed. Initially the T/P element was changed every 100 hours then 200 hours then 400 hours.
Oil samples were taken and analysed with every change.
The last report was that this engine showed no adverse wear as noted in the oil sample.
The PAYBACK?
With improved filtration older engines are cleaned of harmful deposits that OEM filters can't/don't.
Brothers please consider that I was23 years of age when I did this projects and I'm 67 now, some facts may not be exact but the end rsults aren't.

All right - I'm hooked on doing the bypass on the 300SD. I left an e-mail with AMSOIL tech support and they indicated that I needed to use the BMK11 single element kit with the BE90 filter cartridge. I need to look at the catalog to see what that is. He indicated that the only other thing to pay attention to was an adapter to screw onto the oil sender port. I haven't looked at it yet, but I want to get my ducks in a row...

I want to get a schematic together before starting. I know there are oil cooler lines to deal with and such. Well, we'll see how it goes.

please post pics!

That would be great if you'd take pics and post the installation in detail so grateful others could follow in your footsteps =]

I ran the Amsoil BMK-11 in my DIESEL Volkswagen (2000 Jetta). It worked VERY well. Didn't change the oil for more than 53,000 miles! I only changed it to try a different kind of oil. The Amsoil KIT comes with hose and hose connectors and is generally of very good quality. Two things that are missing are the fitting for the supply and return. The METRIC FITTING does NOT work on Mercedes at the oil pressure sending unit (at least on OLD diesels, e.g. 1983). It does work on Volkswagen. For return line on my Volkswagen I used a hollowed out drain plug. If ANYONE has information about this for a Benz, please email me or post it! I have not installed a bypass filter on my '87 300D yet but may. I currently run fully synthetic diesel oil and oil analysis says 1.9% soot after 6750 miles with low iron wear (23 ppm). This is after 16000 miles of synthetic cleaning out the engine - smoking reduced noticably.

Brian:

During that 53K mi. run w/o an oil change...I take it that you were performing an oil analysis periodically?

Do you have the analysis numbers at the tested intervals that we could look at?

What factors determine when the oil needs to be changed...not levels but rather the individual factors like soot, etc.?

Hi. Hope this helps. What we do at www.wetstar.com is to provide for an adapter donut (if you have a spin on oil filter) with a side port fixed with a theaded nipple and controlled leak (as easy as replacing the oil filter), pass through a Parker-Hannifin bypass filter with a bracket (nice compact size) and go directly to a properly tapped/threaded drain plug. Alternatively, we provide the plug with a male (small end) quick disconnect to undo the drain plug for and oil change once is disconnected from female connected to the return hose. Easy install, now if you have a cartridge then the access is a bit more complicated sending unit, port, and ....... Later....

Instead of having to mess with the return line fitment issues, why not spend a few more dollars and get something like the Amsoil BMK-13 kit? This would seem to take care of any of those issues.



This would also seem to make it easier to remove and install filters.

I saw that on the web site, but how would you handle the oil cooler lines with that arrangement? The nice thing about the BMK-11 is that everything else would remain intact.

cartridge filters...

the reason why we aren't all super happy and using the bmk-13 is because our mercedes all have the cartridge type filter , not the spin on. If anyone has a spin on, they should have installed the 13 kit already and should be smiling. I'm so annoyed my benz has the stupid cartridge filter.

Has anyone figured out the correct thread size for the oil sending unit fittings?

Most people tap the return line into the valve cover, sometimes oil cap, or down thru the oil drain plug(modified). Although the drain plug seems to be the easiest, i've heard from people with jetta bypass systems, and they've said the drain plugs can be unreliable. Doesn't matter how clean the oil is if its all on the pavement :-)
