oil by-pass filters

[JTreas]

ok guys-need info, read about amsoil, fs2500 and about frantz. after reading about each my head is kinda spinning, which filter unit have you guys used and why?, if i started using one do you think it would help mileage after a few thou miles?, gonna do the change to syn oil.

 

[Gary - K7GLD]

My personal opinion - no MPG gains from a bypass oil filter - and for my money, the BEST filtration is from the TP element filters like the Frantz I use - but ones like the Amsoil work just fine, and are lots easier to maintain.

 

[CKelley1]

gary is correct absolutely no change in mpg, the 04. 5 up motors need a bypass filter more than the others , the frantz is the best but you will spend all of your time changing them the fs2500 is over priced and overrated the amsoil with the 110 filter is the best of the kits i prefer to make my own, what ever route you go run the bypass until it clogs up before changing filter , just place your hand on it about once a month after running if it is warm it is still working

I am running the Amsoil set up seems fine , long term results a long ways off. TP belongs in the bathroom:-laf

WELL, maybe except for keeping your engine lube looking like THIS at 5-7K miles:

And this:

Somehow, oil that clean, after running it thru butt-wipe for 7000 miles, sure puts a grin on MY face!



AND, oil analysis reports like this on oil that's been in use for 20K miles, is easy to take as well:

great numbers

 

[JTreas]

so you just run the tp or frantz filters till they clog? or have you guys seen a specific number of miles then change them? and are the frantz filters you buy better than regular tp?

 

[05mxdiesel]

The key is changing the tp rolls before they clog and dirty up the oil. 2-2. 5k miles is what I do, the makeup oil is a plus to keep the additive pkg up as well. A few of us, gary included has started using the frantz rolls, but the scotts 1000's work well too. The frnatz rolls fit the cannister better and are rolled tighter than the off the shelf scotts.

I run the fs-2500 on my 6. 7ltr and my soot levels come back great. The next analysis I will do on my oil will be 15,000 miles on oil. In my opinion its not overpriced or overrated, Right now it is doing exactly as advertised. My oil is not ever honey colored though. I don't have the audacity to say if it is the best or not.

How does your oil stay so clean? I have a 06 and I can change all the filters and the Frantz, new oil, start her up, and before I can check for leaks the oil is black and stays that way for the next 10000 mi. I change the Frantz every 2500 mi. and the fleetguard every 10000 mi. then i start all over again.

mine is staying very clean has been installed for about 4000 miles, after 1000 miles installed Frantz changed both the oil filter and the toilet paper with scotts. have since got the frantz paper. I have close to 2500 on the second roll and oil is slightly colored. I might go with synthetic next oil change. Will change the frants paper soon. Ed

With the oil bypass filter setup, overtime, does the bypass help prevent the oil from getting "thinner" (i. e. diluted)? Or one of the reasons for oil to 'appear' thinner is based on mileage?



I recently bought a used '04 CTD and just chg'd the oil (3k), 15w-40. Stock setup. It seemed to me (a newbie) that the oil was "thin" and flowed out of the oil pan somewhat like water. I have read some of the other threads re: "thin/diluted oil" relating to possible injector/CP3 leaks - hence, fuel mixing in with the oil. But I am trying to watch for the various leak signs folks had mentioned. I plan on doing an oil analysis soon to get my numbers, which may point to fuel in the oil. I don't want to change the course of this thread, if my issue is related to 'fuel in the oil'.

Oil is going to turn "BLACK" in use no matter what kind of filtration system you use, as the "black" is sub-micron "SOOT" particles.



Soot comes from the combustion of diesel fuel and is a problem because of tougher emission regulations. Less soot goes out the exhaust now, but more goes into the oil.

No, the Frantz and other bypass filters will only filter particulates, not separate liquids (e. g. fuel from oil)... it will not protect from a failing injector.

HOWEVER, the length of time to turn black varies greatly between filters... some have finer filtrations and better holding capacity than others.

AMsoil custom kit here. love it.

VERY TRUE, Steve, and better engine oils control soot by keeping the tiny particles finely dispersed instead of letting them clump together. Although this process is not fully understood, we do know that it depends on additive chemistry and that some additives do a better job of this than others.

Odds are he has an '04 or earlier truck without the third injection event. Even with a bypass filter it's a fact of life on the '04. 5 and up trucks your oil is always gonna be black no matter what.

I can keep mine clear for around 4k, but it takes a GCF to do it... :-laf

Oil analizes of todays modern oils have proven you can run them safely up to 8-10K miles before you delete the additive package, but what wears your engine is the dirt particles that accumulate in the oil in that length of time. I am a big believer in the cleaner you can keep your oil the longer your engine will last... semi owners have known this secret for years.



My uncle drove semi trucks for 50 yrs & told me he got 3 million miles out of his truck that had a by-pass filter on it that held 3 gallons of oil (the truck held 16 gallons). He said after an oil change he could run coast to coast & the oil would be as clear as honey.



I installed a Frantz By-Pass Oil Filter on my 2009 Ram 2500 6. 7. I choose the Frantz because it is advertised to filter out particles down to 1/2 micron verses the 3-4 micron of other by-pass filters & it will remove up to 6oz of water out of your oil also. I made a bracket out of 1/4" steel & mounted it on the top front drivers side of the engine, I can change the filter in less tha 5 minutes plus TP is very cheap compared to other by-pass filters.



I know the claim of of also filtering out water might be questioned but a close friend of of mine who owns a body shop uses a Frantz By-Pass Oil TP Filter to filter out water in his air compressor he uses to paint cars with... so as the say "the proof is in the pudding".
