Bypass oil filter systems

Found a interesting document that talks about it. the one point it brings up is to truly filter soot of of your engine oil the bypass filter needs to be the centrifugal type. Is the amsoil bypass system lots of you using centrifugal? Is it actually really necessary to go this route?

Claim number 6 is kinda bulls$it. I monitored my soot levels through sampling when I first got my truck. Every single oil sample was somewhere between 3 and 4 when the sample came back from a lab. I put on an el-cheap bypass oil filter system ( Amsoil - no affiliation, just happened to be the brand eventually chose) and the very next oil sample it had dropped to 0.2. All oil samples after the install, the soot levels never got above 0.4 at any time. It was roughly 10% or less of what it was and iron and all the other wear metals dropped slightly too.

I never informed the lab I was sending my samples to what I had changed. All I know is that there was a clear difference in soot levels. My Cm871 was a soot monster that had emissions issues as early as 180,000 miles into its life and the stealershits/cummins was of zero help to me towards solving any of those soot and emissions system problems. - I went to about 15 different stealershits for both cummins and international trying to find the Cummins 'Centraguard' bypass oil system to put on my engine and they all starred at me with a blank stare. I WANTED THE OEM BYPASS SYSTEM ABOVE ALL!

Not a single one of them had even heard of it. After educating them by showing them the documentation directly from cummins, they all just gave me me bulls$it excuses as to why they could not order the system or install it. A couple of them called the red engine maker and got the same bullsh$it answer. it was roughly "The regular oil filter for the ISX has bypass filter built in and you don't need anything else". -- What a complete f$king joke!. - If that were the case,.. like implied in that article you just posted there,.. then the bypass system I ended up installing later would have made no difference in the oil.


I found out in the end that my engine did not have enough oil pressure to make that system work properly and gave up on it. I then started trying to get one of those gulf-coast filters on my truck only to find out there was no place to mount it, as it was too damn big. - Hence the el-cheapo Amsoil one that fit next to my fuel tank.

I only ever took my truck to a stealershit one time to have something fixed under warranty, mileage at 280,000 miles. I had a printed bumper-to-bumper warranty good for 300,000 miles as thick as an encyclopedia that described every single system, bolt, screw, component, etc. and what it covered. -- I had egr system issues (thought it was the turbo though), severe engine hesitation, and fuel mileage dropped from 6.8 to 4.0 or less. I was no longer profitable with the truck at that fuel mileage.

They had it for a week and when I got it back, I had to pay $890.00 EVEN UNDER WARRANTY for some BS excuses they claimed about jump starting it and ordering parts. Drove it out of their gate and they fixed ABSOLUTELY NOTHING!!!!. Fuel mileage was still below 4.1 on it and fuel severe pedal hesitation/power loss was still there.

I learned how to fix the truck myself after that and swore I would park it in a junk-yard before ever taking it to another stealershit or OEM represented facility. -- I still feel this way after more than a million miles and have not had my truck to any of those places since.
