Hey all,

I wasnt sure were to post this so i thought since its related to engine oiling, it would fit in here. I'm considering buying a frantz filter system, I wanted to know what you all thought, if it is worth the money, how the installation went , etc. I'm going to put it on a 1998 saturn sl2 if i do get it, i just wanted everyones opinion before i dropped $200 on it.

Thanks all,
Ben

Does it still use toilet paper filters?

I have seen both the screw on and bypass systems. Some people swore by them, but I have seen actual filtering capacity tests and they really do not remove that much more dirt than today's filters do.

You might want to look at the AMSOIL bypass filter system. It is designed to work with their synthetic oils.

yeah it is still using the toilet paper filters. The only thing that has got me thinking is i know most filters today only filter down to 10 to 20 microns, whereas this filter is supposed to filter down to 1/10 of a micron. It would seem logical to me that you want your oil to be filtered of all its impurities as much as possible. thanks for the input

The first pass efficiency may be 1/10 of a micron but the long term efficiency is not as good as a spin on.

The toilet paper has a tendency to channel, that is develope a HOLE thru the paper and no longer provide the filtering for which it was installed. You have to change the filter quite often to insure this does not happen.

Frantz also used to specify a specific brand of paper due to its ability to do the best job. Do they still do that? Most toilet paper today is also perfumed and that is not compatable with good lubrication desires.

Take some toilet paper and soak it in brand new oil. Watch what it does. Take an equal amount of paper and soak it in used oil. Watch what it does.

yeah i think they recommend scott 1000 tissue paper. My dad was telling me (he works on ammonia compressors) that the company he works for requires the compressors to have sub micron filters, which he said looked very much like a roll of paper towels. I've read a lot of websites were people have installed the filter and have not heard of the problem of channeling, but i am not saying that you are wrong either. I appreciate the comments.

You can't compare a filtration system on an ammonia compressor to a car system. The ammonia compressor operates at obscene pressures and is able to push product through a very restrictive filter, quite unlike a car. A Mobil 1 or Puralator Pure 1 filter does a far superior job at removing debris without restricting oil flow too much. The Frantz system is not passing all your oil through it, only a small stream. A spin on filter passes all the oil your engine gets through it, unless it is clogged or the bypass valve has malfunctioned.

I find it hard to fathom that in this day and age of instant information that they are still selling the antiquated Frantz system.

Just my 2

franz filters

toilet paper is for wiping your ???????. modern spin on oil filters are all you need. engine manufacturers such as cat say use any ad on by pass you want but dont ext ed the change period, plus what happens when the t paper channels and small parts get into the pan.use good oil specked to your engine and a good filter, spend the franz money on gas use the t paper for what is ment for . my view cliff

well, im always about trying things out that interest me, im only going to be out a little money and it will be a good learning experience. I've heard different things about it from different websites, forums, etc. I dont think any product ever really gets a unanimous decision to whether it is a worthwhile product or not, but as always i do appreciate the input.


P.S. here is my problem though, why would the government try to implement this technology if it was useless?

re: frantz filter

Greetings,This is my first post. I came on line a not long ago because of my reinterest in Frantz oil filters. I had been driving for years before they were introduced. I have used them for years and gradualy stopped. I still have three one on my 50 Chevy moving van and two on the shelf. I plan to instal one on my tractor, and one on my 4wd chevy van. I will instal one on my GmC safari if room permits. The Chevy moving van has the same engine I put in when I lived in southern Cal in 1970 and is still nice. I have never been able to get oil that was clear as honey but clean and light was no problem. I'm a journeyman mechanic, When I worked on VW's I had one on my Vdub. I have been reading posts on different forms and on one form some guys only posting to heckel the fellows who wanted to exchange info about the filter, thats too bad. I took a couple off the shelf and cleaned them up one still had a roll in it so I put it in the stove, I live in the mountains now, and it burned like a log. I didn't have a fitting that cut the oil intake down I used brass valves, I may do it different now. Richard

well, i know this is an old post but i see Jmark replied today. i have a story for you:

when i was taking automotive in college many years ago i remember a rep from frantz coming into our class to talk about oils. at the start of the presentation he had a rig with a frantz filter, recirculating pump and a glass resovoir. he put a roll of toilet paper in the filter and asked for some drain oil out of the shop. the rig ran during the presentation and when it ended the oil looked like it was just poured out of the can--brand new...I WAS IMPRESSED!!! :D have i ever used one? no. why? i don't know. i just change oil and filters regularly.
i forgot about this a long time ago but as soon as i started reading this thread it all came back. from the demonstration i saw that filter definatly works!!! :D

Confirmation of oil color and quality

Hi everyone. New guy aboard here.
I just wanted to share my dipstick oil color to confirm what results Jmark had.
This oil has not been changed in the engine for approximately four years and is just like new. I'm out of the oil supply so I don't recall what oil I actually used but it is not synthetic and it was just off-the-shelf oil. I use 30W.
I do have a very old model Frantz Oil Filter installed on the car and change the TP regularly with Frantz brand for best results.

I bought this car originally in '88, sold it to my niece who was in high school, and bought it back from her when I learned she was going to trade it in on some used T-bird. Gotta love those Samurais.

Frantz Filter

Greetings, I installed one of the Frantz I had on my Tractor a Michigan 55A, and another on our 1994 GMC Safari. On the Safari I tucked it next to the steering column, the miles on the Safari is near 240,000. I didn't change the oil or filter on ether after install. I use Scott tp. Years ago I didn't know which paper to use and for years used what ever we had with no bad effect I know of. I live in the mountains I put used filters in the wood stove, they burn like a log given enough of draft. Richard

Richard,

Did you find any issues with the cardboard center tube being too large? I haven't found a toilet paper that fits nice and snug over the metal center tube in the filter unit yet. That's the main reason I use the TP from Frantz Oil Filters.

I note some users actually cheat by using rubber "O" rings around the metal tube to take up some of the space preventing unfiltered leakage.

RE: cardboard center

Greetings, yes the centers are too large I wrap tp around the post before pushing on the roll. You have to take quite a bit off to get the can to fit. I tamp the tp between the post and the cardboard so the oil doesn't find a freeway past the roll. I saw another user that used Orings on the center post but the Oring I have are too thick, this way seems to work. Have you installed one or thinking about it? Richard

Richard,

Yes, I've installed MANY of them. I actually sell them but that's not why I'm here. I have three on my vehicles and one on my tractor. I am one of very few who actually installs them for my local customers.

I have not heard of wrapping TP around the center post before installing the TP in the unit. Actually, I like that much better than the "O" ring procedure but when you compare how nice the Frantz TP fits on the center post and the low difference in cost, you probably would not use toilet paper again.

After this explanation I hope I'm not offending anyone or sounding like I'm pushing the product.

I see a lot of negative comments here by folks that have never used the Franz bypass filter. I bought a system in 1963 for my 55 Chevy 265. It came with a strip of paper that was divided into 4 squares each one designating 500 miles. You were to place a drop of engine oil at that mileage for each square and watch it oil clean up. It works and works well. I can't see why one would not want to add this product help protect and prolong the life of their engine.
