Oil bypass filder. Do they work?

[RSchwarzli]

Hey guys, I keep seeing ads for the oil bypass filters. Do they work? Are they worth investing in if you plan to keep your truck for a while? Anyone have any thought?



Thanks,



Robert

I think they are worthwile. I am getting ready to install one on my 2006 here very soon. it will really make a difference in the amount of impurites suspended in your oil, leading to less wear and with some fluids, less maintenance.

I had the opportunity to tear down a Ford engine that had a toilet paper bypass filter and extended oil change intervals back in the 50s. I have chosen not to use same. There is no substitute for clean oil and filtering certainly helps, it just has to be done correctly and on a regular basis. I have seen oil filtration/reclamation systems that keep the oil clean and looking like it did when it was put in but not an an automotive engine. The oil gets unsuitable to use after a certain period of use and needs to be replaced, I am uncertain what that period of use is so I will rely on the Mfg. recommendations for now. bg

YUP - the best bypass system in the world is no better than the care and regular maintenance it receives - just like the medicine in the cabinet won't help if you don't follow instructions and USE it properly!

By-Pass Filter

I now have 300k on my cummins w/bypass filter. Have varied the change intervals and settled on 1500 to 2000 miles for filter element change. I use oil analysis at least once a month ( 10,000 miles ) I am totally happy with the results I am getting. If you decide to go this route, I strongly reccomend you base your decisions on regular oil analysis along with your personal needs. Analysis at Speedco takes about 30 min. and changing the element takes about 15 mins. I've noticed most of the bad-mouthing on this subject usually comes from those with little or no personal experience using the product. :-{} R C

HEH HEH HEH - you noticed that too, did ya? :-laf :-laf :-laf

Well for you guys that use sampling try doctoring your sample once and see what happens add a bit of diesel to it to dilute it and the sample it see what happens just for S*&T sake then see if you still believe those things

by pass filter, Do they work ?

MY THOUGHTS OIL IS CHEAPER THAN PARTS , CHANGE IT , IM CHEAP



$ 30. 00 CHEAPER THAN $ 300. 00 , but im nutral i chage the oil often and keep it clean , some engines you cant like my jetta , stupid oil filter design :-{}

Nope... bypass filters don't work. They just look purty... that's what everyone uses them :-laf

Hmm, don't know if it's the RP high performance oil and / or the OilGuard bypass filter.

Here are photo's from the #1 valve cover and the front timing cover at 160,00 K. Used the RP since 5K and the bypass filter since 115K with once per year / 25K oil change intervals with OEM full flow Fleetguard oil filter changes at 6k Average.

The #1 cylinder valve train can be seen at this thread - https://www.turbodieselregister.com/forums/showthread.php?t=171949

$ 30. 00 CHEAPER THAN $ 300. 00

WELL, I paid about $50 each for mine - and the first one included installation! :-laf



Of course, that was back in the 50's... :-laf



As to measured vs theoretical efficiency of bypass filters and analysis outfits - or, how honest and accurate the oil analysis REALLY is, all I can say is, when I installed mine on the '02, analysis came back with an IMMEDIATE drop in contaminant levels - and the analysis outfit had NO way to know what I had done!



More recently, I was puzzled at the sudden appearance of Molybdenum and Boron in my analysis report where none had been before - then I discovered Chevron had started including those in their improved additive package.



NOW, I realize that providing "proof" for guys who are dead-set against something is an exercise in futility, since usually NO amount of proof will change a prejudiced "Don't confuse me with FACTS, my minds already made up" mindset - so I don't really expect what I offer above will convince or sway the original critic up above.



But it sure convinces a gullible guy like ME!



All that said, I'll certainly agree that constant oil analysis IS a distasteful added expense, and I only do it as often as I do because of the steady stream of tests and experiments I do, and then present here to share with the guys who's curiosity on lube related issues matches mine.



The dedicated doubters? Well.....

I have one on my 6. 9. I don't know if I'll put one on my 06 CTD because the engine will probably go 400K to 1 million miles without it, just by doing good maintenance. So it will probably still be a good engine when all the Dodge around it is worn out. Question for you guys that do. Does the oil stay honey colored or not? That has always been interesting to me as I have John Deere that the oil stays that way like a gas engine, and I've heard of other diesels doing this. However it seems that the oil should get dirty to suspend the soot in it? My truck is kind of like a hobby for me and others on here as well, so I may put one on it. Oh, as to the original question, go to bobistheoilguy.com and you can read all about bypass systems and microfiltration to your hearts content.

As to the oil staying "honey colored", yes and no. :-laf



Here's a pic of the oil on the dipstick of my truck at 5000 miles - Frantz filter, Delo 400 15/40



#ad




Now for reality. That was back before most of the mods done to my truck, and also when most of my driving was longer distance type, and far less short haul stop and go as I'm now doing since relocating here to eastern Oregon.



Consequently, my oil gets lots dirtier, faster than it did before, and won't look like the above unless I increase the frequency of element changes. My oil analysis numbers are as good, and better, than ever - the oil just LOOKS dirtier and more repulsive due to soot.



And yeah, I'm like you - I do lots of this stuff for fun, and as a hobby.

Hey Gary thanks, I was hoping you would answer my question. I read a great article about the Frantz? bypass once. Are you the author? I bet yes. What would a ballpark figure be for me to get all I need to have the dual Frantz setup. I would rather have one bypass that you could just load 2 or 3 rolls in. I don't think Frantz makes one though. Do you know anyone that does.

Also Gary, if you bought a new truck tomorrow, What kind of oil bypass would you put on it? I like the idea of the Frantz because the other filters are expensive to replace and don't seem to do any better.

You may be referring to THIS thread:

If so, obviously I was the author of that one - in fact, if you do a thread search on the word "Anatomy" with my name as the author, you'll find some more similar threads.



What bypass would I use on a new truck if I was doing it all over again at this time? WELL, I have yet to see any test results, analysis and particle count, from ANY competing bypass that matches or exceeds what I get from the Frantz in similar usage - the TP type element is a put-off for some guys, and It's hard to convince dedicated critics as to how fast, easy and mess free (not to mention CHEAP!) they are to swap out when installed and changed properly.



But fact is, there ARE some excellent alternatives out there - Amsoil sells a great unit for guys insistent on use of a spin-on type rather than the cartridge type like the Frantz - and while I personally doubt the Amsoil or others will match the Frantz for efficiency, ANY of the popular ones will greatly enhance the cleanliness of the oil FAR above what is obtainable without one - and they ARE transferable from one vehicle to another - the one I use is over 40 years old, and been on about 5 different vehicles thru the years.



Frantz DID used to make a 2-roll unit - maybe even more than that - but not sure if they still do or not - a 2-roll unit would be great, other than finding space to mount it for easy servicing.



Hope that helps - and good luck.

Thanks, I'll do the search and read up, this stuff is interesting to me.

Do any of you guys have a picture of te filters that use TP i think i can make one cheaper than buying one
