Considering buying a Franz Filter - 01/09/18 12:53 AM

Hi Everyone,

I am considering in the near future buying a Franz filter for my Dodge Grand Caravan. It looks like the full kit is a little under $300. I have watched a few videos, and the install looks fairly simple.

It appears the kit comes with a fitting to "t" off of the oil sending unit or something like that (correct me if I am wrong). I plan to drill a hole in the oil filler cap and running the return line there instead of puncturing the oil pan. My plan is to make minimal modifications to the van so I can return the van to stock easily and move the filter to the next vehicle.

Are there other tp filter brands to consider? Any other suggestions or tips?

Thanks for your time,

Brad

1) Use a good quality synthetic oil, change every 10K (typically, YMMV)
2) Use a good glass media oil filter

Following this formula, the rest of your van will likely fall apart before the engine dies.

That's what I would do and have done on my trucks. As far as brands of Tp are concerned Scott 1000, BoardWalk, and Kirkland brands work well. You might want to consider getting a sleeve or orings to seal the center roll to the Frantz tube. If you look on Ebay NOS units come up from time to time, so you don't need to pay 300 for one.

Thanks for the info. Do you change out the tp early or do you leave it in 10k miles? I have a microgreen filter on the van now, and most likely will just leave it on.

Thanks for the info. So my understanding is the oil comes up the center tube and drains through the tp and out the bottom, right? I am assuming the tp must be tight on the center roll, and on the outside of the roll up against the canister as well.

Because I want to. Think of it as a hobby, and something to do. As well, it would be a big plus for the engine to not to wear and use oil as the miles pile on. I tend to keep my vehicles a while.

What expectation are you finding people have with the bypass filter? I don't think my expectations are too high... I would say my expectation would be #1 to extend the oil change intervals to 10k miles (the manual calls for 3k mile oil changes in severe duty) and #2 extend the amount of life the engine has as a non-oil burner. I currently am using a Microgreen filter, and I believe the Franz is a step or 2 above the Microgreen.

Re: Considering buying a Franz Filter - 01/09/18 03:24 AM

I installed one on my car. Mostly as a conversation piece and a laugh. I T'd the pressure feed from the oil pressure sender (which broke off in the block on removal, whee!) and drilled a hole in the oil pan for the return line. I made sure to install a restriction prior to the inlet of the filter. I've had my car running on toilet paper for 60,000km now (out of 320,000), no signs of issues.

I did an oil analysis on my last oil change without the Frantz, and my first oil change upon using the TP filter, and the results were surprisingly good.

I use some generic single ply from Rona (hardware store) - I think it's rebranded Scott 1000, but we can't get Scott 1000 here.

Just about any oil can get you to 10K in Washington's climate.

You'll have to do the math... $300+ is like 30 oil changes, every 5,000 miles is another 150,000 miles without the installation of the bypass.

A bypass filter helps get out PARTICULATE. Only.
It does not improve TBN, or help with shearing, etc.

I said "don't expect stellar results", because you can get your 2006 Caravan engine
to 300,000 miles with just good maintenance.
But I worry about the rest of the van....

I never change my oil on engines I have Frantz filters installed on. I've been using them for the last 50 years so I've saved a lot of cash.
One thing you may want to to consider concerning the oil return line is that it's better for it to drain downhill from the bypass filter. That way it's a lot less messy when you open up the Frantz IF you allow it to drain out the excess oil overnight.

Thanks for your reply. smile The reason I wanted to return the oil in the oil cap is so I can remove the filter with little fuss and return it to stock when I sell the vehicle. My plan is to move the Franz to each new vehicle as I replace the vehicle.

Several questions for you:
1. For the filter change... if the Franz is mounted high, will the oil drain out the intake line if parked for a few hours?
2. Is puncturing the oil pan the best way to return the oil downhill? Any other suggestions?
3. Any results to post regarding using Franz in your cars for the last 50 years? (subjective opinions are fine.) smile

Re: Considering buying a Franz Filter - 01/10/18 12:36 AM

1. Any drainback in the oil pressure line would be very minimal.
2. Some dislike puncturing the oil pan for the return line but I prefer returning the oil directly to the oil pan. I've never seen a problem arise from this practice. Options include using a hollow bolt. When Frantz was owned by SKY, hollow bolts were commonly available through SKY. On many engines you could remove an intake manifold bolt, replace it with the appropriate size hollow bolt and then attach your return line to the hollow bolt. I've even welded steel fittings on some of my oil pans.
3. Other than saving a lot of money on oil changes and keeping the oil and crankcase clean 100% of the time, I once had a catastrophic failure where I lost all my rod and main bearings on a 2000 Subaru due to loss of oil pressure caused by a combination of the bolts retaining the plate on the rear of oil pump and my use of a sandwich adapter. Take either factor out of the equation and I'm sure the failure wouldn't have happened. Needless to say I'll never use or recommend the use of a sandwich adapter again plus using a sandwich adapter, the oil will not drain out of the Frantz back to the pan making filter changes very messy.

Thanks for responding. I read about your problem with your Subaru in one of your threads. That is a bummer.

Now to get a unit purchased! smile

Yes, a bypass filter will help keep oil cleaner - THAT IS TRUE

The facts: having a bypass filter doesn't mean the engine will last forever.

Period.

Over 1,000,000 miles with only one oil change and No measurable internal wear using a bypass oil filter!

See http://www.gulfcoastfilters.com/1%2c000%2c000%20MILES.htm

With a testimonial like that, I would have high expectations.

Whooo! 1 Million miles. That is amazing. I do not expect my vehicle to come close to that (nor would I want to drive the same all that time... variety is nice). What I do want is quality of life for the engine... meaning low oil consumption, no blue smoke at start up, etc.

I bought an used Franz filter. I will need a new base gasket. I looked on the Franz site, and they sell them in packs of 10. I am not really interested in having that many unless they do not last long. Is there another source of gaskets anyone is aware of?

Is the o-ring style or is it the square o-ring?
The old o-ring style doesn't last very long.

I buy mine from McMaster Carr. I believe their minimum is about 25 BUT they're a lot cheaper.

You might want to give Ed Greany an email, he sells the seals for a reasonable price. I bought a 10 pack off him for 10 USD and I have only used 1 so far as they never seem to leak. His email is: [email protected]

I'm a big Frantz fan, but what about Trasko? I have been interested in them a long time but don't need to make trouble where there was no trouble by using one. It threads right on, done. I can't quite understand their logic about how it works. Being designed by, or with help from Subaru, is a good plus for them. No one has used them here?

Huh! That is new to me. That would be easier to set up as no plumbing of a separate bypass filter. And the price is cheap if it is in USD. Anyone have experience with this?

Re: Considering buying a Franz Filter - 01/14/18 04:23 AM

Hi Everyone,

I am needing some people to school me on the Franz filter. Since I am getting a used unit, I do not have the advantage of instructions.

1. It doesn't matter which way you orient the filter, correct? (upside down, right side up, sideways, etc.) Is there a best way to orient it?
2. What kind of fittings are used on the Franz? The used unit I am getting has the fittings in the housing, but not the female hose fitting. I suspect I need the right kind of female fitting so it will not leak.
3. Is there a restriction like an orifice somewhere into the unit? If so, where is it at as I want to be sure it is in it. I imagine the check engine light will come on if the Franz is bleeding off too much oil.

Thanks for your time,

Brad

It's best to orient it right side up so the oil will drain out overnight making filter changes much less messy but you can mount it any way you want.

Push-Loc fittings was originally used. You'll also need appropriate size hose, also available from McMaster-Carr or possibly your local auto parts dealer.

As I recall, there was a built in 1/16" restriction used on the outlet side but location doesn't matter.

Thanks for your replies. The appropriate size hose would be 1/4" inside diameter. right? So the restriction is built in to the housing?

I looked up McMaster-Carr the other day. NICE!

Hi Everyone! I got the used Franz filter today. It even came in it's original box. I don't know how old it is but the box is ancient. Nothing to wear out on these things. I should have no problem moving from vehicle to vehicle in the years to come.

I by figuring out a place to mount it. Turns out there is less room in the Dodge Caravan engine bay than I was thinking. I wanted to mount it topside, but that wasn't going to work. I finally found a good place to mount it which happens to be near the engine oil filter and oil pressure sensor. I got the bracket mounted good and solid.

Step 2 will be going to the store to buy the fittings and hose I need. hopefully I can round up everything I need locally.

Once you get the Frantz mounted and have run your engine for a few days, open up the hood and check the tightness of the ring clamp bolt. Some times when the weather gets real cold the ring clamp can get a little loose (happened on 2 of my Frantz units - the rest stay clamped down good). Just another re-tightening and I did not have any further problems. Other than that, those Frantz filters have held up well for me on my work trucks and engines on my power equipment. Like A310, I use Kirkland TP or the Scott's individual rolls. I also use Viton O-rings I got from a hydraulic fitting shop on the center sleeve to keep the TP nice and snug. I also have one Frantz Oil Refiner, which is the latest version of the Frantz Filter mounted on one of my trucks. I got it from Ed Greany who A310 mentioned. It is a slightly modified version of the original Frantz filter but it works the same way. The Frantz Filters are good, sturdy - long life units.

My unit's band doesn't have an adjustment. That must be the updated one? I bought my fittings today... it was around $60 dollars for everything! Much higher than I was expecting. Now I need several more things, and then I am ready to install it.

What are the benefits you have noticed with using the Franz on your fleet? How long to you leave the oil in the engine before draining it?

Thanks for your information.

Re: Considering buying a Franz Filter - 01/21/18 07:19 AM

You must have one of the earlier models that has the compression ring with the "lever" on it where you just push it closed and put in a pin to lock it in place. All of the Frantz Filters that I have came with a bolt/knob set up where you can just tighten the strap down by screwing the the knob tight. I have not done any oil analysis (send a sample to Blackstone) on my equipment that has bypass filters installed. I read some documents from commercial trucking companies and off road construction equipment operators, that showed that installing a bypass system on equipment kept the amount of particle counts down/ oil cleaner versus a full flow filtration system. Some of my trucks and construction equipment are considered "antiques" by other contractors that I interact with on job sites. They can's figure out how I can keep this old equipment running so good, while they keep having issues with their "newer" equipment. I definitely feel that the Frantz filters have kept the oil clean reducing the wear particles circulating and causing problems. Running Synthetic, I've gone 350 hours on construction equipment before a complete oil change (but I'm changing out the TP rolls and adding a quart of oil several times during that time frame). I change the oil in the trucks around 8,0000 to 10,000 miles - changing the full flow and Frantz at the same time. Last summer, I went to Costco and bought a big package of Kirkland TP and when I got home I just walked around changing out the filters and adding a quart of oil on all the Frantz filters I have installed. I also have remote filters installed on all power steering and automatic transmissions. Those are just regular full flow oil filters. Heck, if it has a fluid line - slap a filter on it.

Nuff said,

Re: Considering buying a Franz Filter - 01/21/18 08:42 PM

Before you mount up the bypass filter, send off an oil sample to get a baseline analysis. I didn't think about doing that with my Dodge before I installed my GCF O-1, and I'm kind of kicking myself for not doing it. It's not a big deal, but it's the only way you'll be able to really quantify the before/after performance.

You're going to want to do periodic oil sampling if you go with longer drain intervals, so a baseline sample is just one more.
Posted By: AlaskaMike

Re: Considering buying a Franz Filter - 01/21/18 08:43 PM

Another thing to think about--if you have a good experience with this installation, you might consider some kind of bypass filter for the transmission. That might even be more important on a Caravan than the engine oil.

Just a thought.

Do you have a Caravan? If so I am interested in what your used oil analysis showed.:)

Re: Considering buying a Franz Filter - 01/22/18 09:04 AM

I do have a Dodge Caravan, but I don't have any bypass filters on it. My Caravan is a third vehicle and isn't driven very much. I've never taken any oil samples from it.

That said, I still think it's worth it if you take a baseline sample before you install the bypass filter. Certainly your choice, of course.

Hi Everyone,

I am getting ready to finish installing the Frantz Filter. I am trying to figure out the right place to put the metal ring. I was sure I knew the right way to use it, but now I am not so sure. Do you put the metal ring in first inside of the canister, and then the toilet paper roll? Or do you put the roll in the canister first and then the metal ring?

One more question... are the Frantz filter a lot better than toilet paper? My plan is to use scotts tissue... but am wondering if the Franz media is significantly better?

Re: Considering buying a Franz Filter - 02/06/18 03:26 AM

Metal ring after you push the TP into the canister. I use Scotts 1000 TB or Costco "Kirkland" TP as my filter choices.

Perfect! Thanks for your answer! I do have one more question... the width of toilet paper has been getting narrower. I doubt Scotts is doing it now, but if they come out with narrower paper, do I push it as far as it will go into the canister and follow it with the metal ring to hold it all the way in the bottom? I guess the question is: is the ring's purpose to make the tp stay flush with the bottom of the canister?

TIA,

Push the roll down as far as it will go. After reinstalling the canister and starting the engine, the oil pressure will push the roll down tight against the screen. Also, always inspect the top of the old roll for any visible contamination such as water or metal particles. Frantz use to call that an "instant engine analysis".

Gotcha. Thanks! smile

It really depends on whn you "catch" the filter flow before it stops up completely, and the TAN (total acid number) when you get an oil analysis (you usually have to ask for TBN/TAN).

I know a few folks who go every 10,000 - then change the roll and add 1 qt synthetic.

Re: Considering buying a Franz Filter - 02/08/18 02:40 AM

I finally got everything hooked up. It works well so far. I ran the outlet hose into the oil filler cap so I decided to take it off to see how much oil is flowing. I was surprised how much oil flows through the bypass filter. I figured it would slow after running through the filter.

There is not a lot of room to run a T fitting off of the oil pressure sensor port on the 3.8 engine. Everything had to be lined up just right, as the T fitting had to be turned just right to clear various things.

If anyone is considering this with the 3.8 engine, here is a couple suggestions. A longer length of male threaded pipe may move the T fitting far enough away to make things work better. Or maybe use a sandwich adapter instead. Also, the oil pressure electrical plug only has just enough wire to plug it in the stock location, so if you use a T fitting you may need to splice in a section of wire.

One more thing for people buying a used unit that doesn't have the fittings... maybe consider buying the Frantz fittings. I ended up spending the same amount for fittings as they charge for their fittings (or more). You will save yourself the headache of spending time in the store figuring out what you need.

Thanks for the information. My plan is to change out the filter every 5,000 miles and top up the oil. My plan is to do a drain between 20,000 and 25,000 miles. That means my oil is left in for 8 oil changes in length.

With a filter change every 5000 miles and your regular full flow filter change you might not need to ever change the oil. I've had my Cummins( 15 quart sump) on this schedule now for 40,000 miles, no oil change yet, just a toilet paper roll every 5000 miles and a full flow every 25000 and the lab says keep using. I also started my V10 gas (6 quart sump) on the same schedule with an oil analysis every 12 months. Keep us posted on your results.:)

A310,

Thanks for your comment. That would be cool about leaving it in indefinitely. Would it matter that I am using Chevron conventional oil, and not synthetic? What do you use for a full flow filter?

Can't see why the conventional won't do the job, I would however check with an oil analysis from time to time to see how the oil is holding up. I'm running an amsoil AEO80 full flow which is rated for 25000 miles.

A310,

Just a quick side track, are you running 5w-20 oil in your V10?

No, I ended up using 5W-30 as that's what I'm using in my wife's explore and have lots of stock. Runs well and good cold starts, so I'm keeping 5W-30 and no additives added. I now have 5000 miles on the engine and changed out the first roll at 4000 miles. Replaced the O2 sensor and got rid of the rich fuel trim setting on bank one, so should help out on the fuel dilution. Engine is running really well and am now code free.:) Oh and went from 9.6 mpg to 13.5 mpg, so happy V10.

Brad ~ You'll love watching ~ this filter do it's job ```

I've used them for many years ~ they use to be $24.00 installed ```
Frantz used to demonstrate them at Flea Markets, years ago ~ I think that was himself ~ I saw at the Rodium Drivein , Gardena, California ~ one weekend ~ when I was about 17 ``

I really like them ~ have collected them over the years ```

Hi Valley Ranch, what shearing are you referring to? Do you have a link to what you read?
Posted By: valley_ranch

Re: Considering buying a Franz Filter - 02/27/18 04:07 PM

Brad ~ No link``` It was not a great description ~ but I have read better telling of what shearing is ```

I'm talking about Shearing of the additives that make~ say ~ A 5W-30 become a 5W all the time ```

Does that make sense ```

Have to go blow the snow ~ I'll be back~ in a bit ```

Ok, I haven't thought about that regarding to using a bypass. I will be frequently changing the filters so my oil shouldn't get a chance to shear down.

Re: Considering buying a Franz Filter - 03/04/18 08:25 PM

Thanks for coming back ~ I use to live in Southern California ~ I used 30W and never changed the oil ~ just added a quart at each filter change ~ ( tissue roll)

I now live in a area ~ with colder winters ~ and feel a multi oil ~ necessary ~ so ~ shearing ~ gives me something to think about ~ with the adding of a quart each change ~ maybe ~ that does it ~ like to know more of shearing ~ how fast ~ how bad ```

Re: Considering buying a Franz Filter - 03/06/18 01:10 AM

Very, VERY FEW engines "shear" an oil down to a thinner viscosity.

Oil naturally gets a "tinier" bit thinner as it ages, then starts to thicken again - FAST.

I would hope a good bypass filter can clean out all the "gunk" that makes an oil get thick.

IMHO, changing the roll every 5,000 is probably a little too often

If it still gets warm pretty fast, it's still doing it's job.
If it doesn't warm up, it is plugged - then it is time to change it.

Its cool project I enjoyed it and benefits definitely out weigh the cost. Two things that cause wear mainly...start up and not filtering down to 2-5 micron area. Its fact published few years ago from GM, that article only referenced filtration though. If you had Bypass and a oil accumulator you would effectively eleminate most all wear.

I dunno - in Texas I seldom have a truly "cold start"

I filter down to 5 microns absolute, so that's really "good enough".

Re: Considering buying a Franz Filter - 06/03/18 03:15 PM

Hi Everyone, so far so good with my bypass filter. I did have several hiccups... 1. I decided to upgrade from the old style clamp to the kind you screw in to tighten. I didn't install it correctly and when I started the engine up I puked out a lot of oil all over the ground. Grrr... user error.

And then... about 800 miles into a trip I checked the oil at a gas station and discovered their was no oil on the dipstick. The clamp had loosened up considerably, and I leaked out over 3 quarts of oil. Not enough to cause engine damage thankfully.

It is possible I didn't tighten it enough, but it appears to be loosening up as I check it frequently now, and seems to need a turn or two to snug it back up. Questions for you guys... anyone have this problem? How tight do you tighten the clamp? Is there supposed to be a locking washer or something like that to prevent it from loosing? The old style clamp has a clip that prevents the clamp from loosening... has anyone made something to prevent the new style from loosing up?

Thanks for your time,

Brad

I'm using that type clamp on one of my installations except instead of using a knob it came with a self locking 1/4 nut. It's not as convenient as the old style over center locking clamp but I've never had any issues with it.

Where did you mount the filter? I mount all the Frantz on a frame or fender well and have had no issues.

I mounted it on a part of the frame that the radiator sits on. It is a pretty stout part of the frame. This morning I used the van so I decided to check to see if the clamp was tight. It was not and I had to give it a few cranks to make it tight.

My Franzt filters were used, so it is possible I am missing a locking washer or something....?

I may need to do that if I cannot find a solution. I like the convenience of the knob but I do not want to junk my engine because I forgot to check the clamp to make sure it was tight.

Re: Considering buying a Franz Filter - 06/10/18 03:10 PM

I had some leaking also on 2500 mile trip, also user error on my part. Teflon tape wasnt right on the oil fil cap fitting made little bit of mess but nothing crazy. As far as clamp goes it definitely needs to be very tight. I had that leak like some have mentioned when I initially installed it.

Let me just say this it needs eye kept on it unlike the amsoil bypass. I kind of regret getting frantz in that aspect cause ive had amsoil kit on previous vehicle and it works perfect...granted EABP90 is also 40$ lol. You get what you pay for generally in life. Cost of ownership is higher on amsoil kit but its also very reliable....

Just a while ago got a 2001 Ford Lariat 5.4 engine ~ installed the Frantz (have yet to run the oil lines, waiting for the arrival of the Sandwich Adapter) had to relocate a smaller Windshield Washer Tank~ to make room for the Filter ```

Looking forward to getting this done ~ have one on each daughters cars ```
