What is a Frantz Oil Filter?
The Frantz Oil Filter is a high-grade, highly efficient "by-pass" filter. This means that a portion of the oil is continually being sampled and cleaned but is being filtered to a much finer degree than it would be by a standard "full-flow" filter.
Who can install my Frantz Oil Filter?
The Frantz Oil Filter is most-often installed by the vehicle owner. It can be installed by your local mechanic or by some Frantz Oil Filter Authorized Distributors in your area.
What tools are necessary for installing a Frantz Oil Filter?
Installation is usually quite simple and just a few tools are necessary. You will need two adjustable wrenches, a knife to cut the rubber oil line, pliers, screwdriver, hammer and occasionally a drill for mounting the unit. We supply the specially-designed necessary punch for some installations for the return oil line from the Frantz Oil Filter back to the engine oil supply.
How long does it take to install a Frantz Oil Filter?
Installation should take anywhere from ½ hour to 2 hours maximum,
What advantages or disadvantages does the Frantz Oil Filter have over a conventional "full-flow" filter?
The Frantz Oil Filter filters particles as small as one tenth of a micron and traps them in the TP Element. These very fine particles are what cause your engine to wear. The larger particles do not easily remain suspended in the oil so there is a tendency for them to settle to the bottom of the oil pan creating your typical sludge. With the Frantz Oil Filter and regular TP Element changes you should not have sludge conditions in your engine. I cannot think of any disadvantages.
How can continually filtering just a portion of the oil be as effective as filtering all of the oil like the full flow filter does?
All of the oil is constantly being filtered and kept clean of fine dirt and engine wear particles which can enter the lubrication system in various ways. The entire oil supply is eventually sampled and filtered through the Frantz Oil Filter at the rate of about 1-2 cups per minute when cold. However, when the oil is operating temperature, the rate can be 5 or 6 cups per minute. At this rate more than 99% of the oil in a five-quart crankcase will have passed through the Frantz Oil Filter TP Element in about 6 or 7 minutes allowing for mixing in the pan. These numbers can vary depending on the viscosity and temperature of your operating oil and your oil pressure.
If the TP Element for the Frantz Oil Filter is so effective, isn’t it rather expensive to replace?
Not at all. Therein lies the real genius of Mr. John Frantz' patented invention. He designed his oil filter to use a filter element that is already widely available and cheap: a roll of Toilet Paper!
It has been proven that this roll of thin paper, manufactured and sold for a different familiar purpose, is also a most highly effective oil filter. In the Frantz Oil Filter, the roll is placed over a hollow upright post where it fits snugly. Oil from the engine pressure source flows up through this central post and is forced downward through the circular roll of paper, "from one end of the roll to the other", so to speak, through about four and one-half inches of densely rolled paper. The oil has nowhere to go except through the paper, which is highly effective in trapping fine particles. The bottom edge of the roll rests upon a metal screen which holds it in place. Filtered oil passes through this screen and is returned to the crankcase.
Why does the Frantz Oil Filter work so well?
Consider the standard full-flow filter from your car manufacturer. It usually consists of a piece of paper or cardboard curved into a circle and is usually corrugated for strength – not for filtering! Then it is placed in a metal housing with a by-pass feature many are unaware of. It is not unlike your coffee filter whereby your coffee water flows through a thin membrane trapping coffee grounds (not always). The coffee filter is VERY thin and porous. The by-pass feature is a safeguard by your manufacturer to allow unfiltered oil to pass through the filter allowing dirty oil to be circulated in your engine. The Frantz Oil Filter TP Element is designed to have your engine oil flow through four or four and one half inches of densely-rolled 2-ply paper before being returned back to your engine and it needs no by-pass valve. After all, it is a by-pass filter!
A bypass filter is a device allowing the removal of solid contamination from lubricating oil. This type of filter is capable of removing extremely small size particles from the oil by providing filtration in depth through a densely packed filtering media. Oil flows through the bypass-type filter and is controlled at a rate so deliberate that it can trap and remove from the oil the extremely small solid particles. Important: This type of filter does not have a bypass valve built into the filter like the car manufacturer’s full-flow filter has. This means that when the filtering element is plugged up in a full-flow filter the oil filtering stops! Not so, with the Frantz Oil Filter which is a by-pass filter, not a full-flow filter.
Why is the Frantz Oil Filter better than other bypass filters?
The Frantz Oil Filter is better simply because it is more efficient. That’s what you want! The TP Element provides a larger amount of filtering material through which the oil must pass thus permitting it to remove more contaminants and solid particles of a much smaller size than the conventional filter. Filtering occurs through 4 ½” of the TP Element instead of just the thickness of a coffee filter in your stock car filter. In addition, it can remove up to 6 ounces of water from the oil. This helps prevent acid development in your engine. Acid requires water to develop.
How efficient is the Frantz Oil Filter?
On the basis of laboratory reports which have been received from independent oil testing facilities, the Frantz Oil Filter is the most efficient oil filter that is commercially available for automotive engines today. Even after many thousands of miles of use, oil filtered through a Frantz Oil Filter will be free of contamination to such a degree that it is considered analytically clean and suitable for further use. There are some who actually no longer get oil changes since the oil retains the lubricating properties and additives removing only contaminates.
What is a full-flow filter?
A full-flow filter is a device for filtering, removing solid contamination from lubricating oil. Full-flow filtration can be the ultimate in oil filtration in that all oil flowing directly to the bearings must first pass through the full-flow filter. However, because of the cost and size limitations, the full-flow filter is no more than a coarse strainer and must be built to guarantee against restricting the oil supply to the engine. The demands of the engine require that bypass valves be built into the system to ensure an oil supply to the bearings when the filter will not handle the required volume. These bypass valves bleed at 3 p.s.i. and open wide at 9 p.s.i. differential pressure across the filter. These pressures may be frequently exceeded on starting the engine and also during normal operation when the filter becomes restricted with contamination. When this occurs, unfiltered dirty oil bypasses the filtering material inside and flows directly to the bearings. Despite its practical limitations of keeping the oil clean, it does provide the bearings with some protection by removing particles larger than 10 microns in size.
Will a full-flow filter or a bypass filter provide the best protection for an engine?
The best filter protection that can be economically provided for an engine today is the combination of a dual filtering system to include a full-flow filter and a bypass filter.
Is there any way that I can visually distinguish a bypass filter from a full-flow filter?
Generally on automobile engines, a bypass filter is connected independently to an engine with external lines. The full-flow filter is normally attached directly to the engine block without external lines. Occasionally a full-flow filter may be installed with external oil lines like with classic year cars; however, these lines will be larger in diameter.
Will the Frantz Oil Filter lower my engine oil pressure?
No. The engine oil pump will produce many times the volume required by the engine and the by-pass filter. Most of the oil pumped is excess and returns directly to the crankcase through the oil pressure regulator valve. The Frantz Oil Filter utilizes a specially-designed orifice which the oil passes retaining the normal oil pressure your engine requires.
Will the Frantz Oil Filter solve the problem of fuel dilution?
Fuel dilution of lube oil is a problem that no filter can solve. Fuel dilution is not a problem in a properly-adjusted engine as the fuel is evaporated from a hot engine crankcase at a rate which is dependent on the engine temperature reached and the time maintained relative to the number of starts made or the amount of raw fuel added by an engine malfunction.
Will the Frantz Oil Filter remove acid from the oil?
The Frantz Oil Filter will not remove acid from the oil but it can prevent the formation of corrosive acid by removing the water from oil. Without water, corrosive acids cannot be formed. Numerous laboratory analyses have shown no acidity content in oil filtered through the Frantz Oil Filter even after many thousands of miles of use.
What is the oil-cleaning capacity of a Frantz Oil Filter?
Each single unit will clean up to 8 quarts of lubricating oil and can be up to 10 quarts with more frequent element changes. Two single Frantz Oil Filters may be installed in a "parallel" sequence to provide sufficient cleaning capability for those engines with a crankcase capacity exceeding 8 quarts and up to 20 quarts.
Why are clamps needed in addition to the push-on hose fittings?
Although push-on hose fittings were originally designed to form a perfect seal, it has been determined that the additional use of Oetiker clamps provides prolonged safety and security of the hose connections. This is highly recommended by the current manufacturer for long term use and satisfaction.
Does the Frantz Oil Filter oil or fuel line wear out?
The oil line used with the Frantz Oil Filter is the best quality fuel line obtainable for its purpose. It will give years of satisfactory service with little or no maintenance; however, like any rubber-like material, it can become weathered over a period of years. If the Frantz Oil Filter is transferred to a new car, we recommend that the hose be replaced as a safety precaution. When oil line shows any indication of deterioration (hardening or cracking) it should be replaced.
What is the effective life of the base tetra seal?
Gaskets of ALL materials have a limited life. The standard practice in the filter industry is to replace the gasket each time the filter is removed whether or not it is deteriorated or damaged. Rubber-like gasket materials take a permanent set under compression, particularly under elevated temperatures which tend to speed age hardening. A good practice would be to change the gasket on every 4th filter change. Thoroughly clean the gasket and groove when reusing or installing a new gasket. Dirt is frequently the cause of leakage.
Is the steel locking clamp safe?
Yes. This "over the center" locking clamp is one of the most positive pressure clamps available. Tests that were first conducted by an Engineering Department of the previous manufacturer in Stockton, California, revealed that this locking clamp firmly held the cylinder kit to the oil cleaner base at pressures above 400 p.s.i. Needless to say, this oil pressure far exceeds of any normal oil pressures which would be encountered in actual use. Note: The Model C, 2nd edition, manufactured from 1976 to 1988 and the newly manufactured Model 2000 uses an "over the center" clamp with a "T" bolt and black knob for better stability. This new type clamp is required on many aircraft engine low and high pressure oil fittings and other engine parts including fuel and oil pump assemblies.
Can the Frantz Oil Filter be used to clean lubricating oil on marine engines?
Yes. The Frantz Marine Unit is recommended for this type of installation. With the Model 2000, the canisters are made of solid stainless steel and the aluminum bases are "powder coated" to resist corrosion and rust.
What happens if the tissue element is not serviced for an indefinite period?
The tissue element will become clogged with solid contamination and shut off the flow of oil through the Frantz Oil Filter.
What is the flow rate of oil through a Frantz Oil Filter?
The normal rate of flow of 30 weight oil at a temperature of 180 degrees and 30 p.s.i. is approximately one quart per minute. This flow rate will vary depending on oil viscosity temperature and oil pressure.
How efficient is the Frantz Oil Filter?
It has the ability to remove any solid particle down to 1/10 of a micron (.000039") and up to 6 ounces of water.
What quality or type of hose is used for the Frantz Oil Filter?
The oil line supplied for use with the Frantz Oil Filter is a "lock-on" type fabric reinforced neoprene line for use with lubricating oil and fuel. This oil line is rated at 200 p.s.i. constant work pressure at 300 degrees and a guaranteed minimum burst pressure of 800 p.s.i.
What is the base gasket made of?
The base seal, or gasket, is made from the finest quality material available. It will give many months of trouble free service under normal conditions. Each time the Frantz Oil Filter cylinder is removed for servicing; the base gasket should be wiped clean and inspected. Eventually, the gasket will harden and develop a groove from the edge of the cylinder, which will lead to oil leakage. Gaskets should be replaced at least once a year to assure reliable service.
The flow rate of the Frantz Oil Filter is primarily controlled by a restricting orifice located at the "inlet" opening in the filter base "or supply line to filter". This orifice is the standard size for bypass filters as required by Federal Specifications F-F 351a, and is the size used by most oil filter manufacturers in their bypass filters for automotive engines.
The lubricating oil pump, in any engine, has the capacity to produce many times the volume of oil required by the oil system of the engine. Most of the oil volume produced is bypassed by means of an oil pump regulator valve and dumped directly back into the crankcase. The very small amount of oil diverted by the Frantz Oil Filter is supplied from the excess oil produced by the pump. When properly installed on a normally functioning engine, the Frantz Oil Filter cannot lower the oil pressure or "starve" an engine of oil to the extent as to cause damage.
What does it mean when you say the Frantz Oil Filter can be used as a "barometer" for preventive maintenance?
Due to the unique filter media and construction of the Frantz Oil Filter, it is one of the greatest indicators of engine malfunctions. "Reading" the used tissue element and making a visual comparison with the Instant Engine Analysis chart provides an early detection of engine malfunction when abnormal deposits are seen. Such early detection of engine trouble can prevent more extensive damage and save you costly repair bills.
What are the recommended Service Intervals for a Frantz Oil Filter?
After you install your Frantz Oil Filter, the first element change should be at 500 miles. Thereafter, these standard guidelines should be followed.
- Gasoline engines: Change your TP Element every 2000-3000 miles.
- Diesel Engines: Change your TP Element every 1500-2500 miles.
- Change more often for dusty driving conditions.
How am I supposed to service my Frantz Oil Filter?
Always service your Frantz Oil Filter after your engine has been turned off for at least 1/2 hour. The steps to replace the TP Element are:
- Remove the Clamp.
- Pull off the Canister.
- Remove the TP Element.
- Replace with a clean new TP Element. (TP must be 2 ply, 500 sheets per roll, for optimal performance.)
- Replace Canister.
- Replace Clamp.
- Top off your engine Oil Level: (Usually less than a quart)
My Frantz Oil Filter does not have the same kind of clamp you show on your website. Do I have the wrong one?
There are several types of clamps used with the Frantz Oil Filter. The latest and newest is a black knob with a "T" bolt type. An older version is an "over center" type. If you have not had any problems with the older version coming undone, you should be fine. To change out your TP Element, you either unscrew the black knob and lift off clamp or swing the safety "D" clip out of the way, and snap the clamp open and then lift off. Occasionally you will see a very old outdated model that has two long bolts with large knobs at the top.
Now that I have removed the clamp it seems as though the canister won't come off. What do I do?
To remove the canister, rock back and forth and twist a few times to release the vacuum. When off, use pull ring to remove old TP Element. Wipe canister with a clean rag. Replace pull ring into a new roll of TP Element and push it back into the canister. If using commercial toilet paper you may need to remove a couple wraps to get the TP Element into the canister; just be sure it is snug & not too tight or too loose. TP Elements ordered from me do not require and size adjustments like that. Simply push the TP Element in with the heels of your hands as far as it will go. Wipe the base gasket clean. Slip the canister top over the base tube and give it one hard hit with your fist for a good seat. Replace the clamp making sure that as it tightens, it pulls the canister flange toward the base evenly and together. If your clamp has the "D" clip, make sure you snap it in place too.
Does a Frantz Oil Filter have to be mounted in a certain position for proper operation?
No. Since the Frantz Oil Filter is pressurized, it can be mounted in any position. (Right side up, Upside Down, Sideways or at an Angle)
If I do not have access to the oil pressure sending unit on my vehicle, how else can I provide the pressure feed into the Frantz Oil Filter?
If access to your vehicles oil pressure sending unit is either difficult or impossible, we offer for an additional cost, an adapter ring that can be placed between the engine block and your spin-on full-flow filter for an easy installation.
Can't I still use any brand or type of TP for my Frantz Oil Filter?
When the Frantz Oil Filter was first invented, the variety of toilet paper choices was slim! It is true, that you used to be able to go into any grocery store and buy the brand on the shelf. Unfortunately, this has changed in the last 20 years. The choices of toilet paper available today can confuse the average person! For optimal performance of the Frantz Oil Filter, it has always been recommended to use a 2 ply 500 sheet per roll, facial quality toilet paper. The purpose for these specifications is so that you will obtain the most densely packed roll of TP available. If you cannot find a 2 ply 500 sheets per roll in your favorite grocery store, we suggest that you try the commercial or janitorial supply companies to find some. If you still cannot find or buy any, we do have it for sale either in four packs or by the case!
I changed my Frantz Oil Filter from my old car to my new one and I now have a leak problem around the base clamp. What is wrong?
If you have moved your Frantz Oil Filter from an older vehicle to a newer one and have a leak problem, you may need our 1/16" orifice restrictor to help control the pressure of oil flow into the unit now. This can happen with vehicles that have a higher than normal oil pressure pump. Leaking is caused when oil is forced into the Frantz Oil Filter faster than it can exit.
Since toilet paper is bio-degradable won’t my Frantz Oil Filter disintegrate causing paper to flow throughout my engine and cause damage?
While toilet paper is designed to disintegrate in water, it has a quality of retention in oil properties. It also rests on a screen base and has a snug fit inside the filter container.
Can I use the Frantz Oil Filter on other engines besides car and truck engines?
Yes, absolutely. The Frantz Oil Filter will work perfectly on most any combustible gas or diesel engine including boats, tractors, heavy equipment, busses, generators, compressors, motorcycles, jet skis, snowmobiles, and even cooking oil for our home-made fuel friends.
Can I use more than one Frantz Oil Filter on my engine?
Yes, you can but it is probably unnecessary. Each single unit will clean up to 8 quarts of lubricating oil and can be up to 10 quarts with more frequent element changes. Two single Frantz Oil Filters may be installed in a "parallel" sequence to provide sufficient cleaning capability for those engines with a crankcase capacity exceeding 8 quarts and up to 20 quarts.
Where can I install the Frantz Oil Filter if I am cramped for space under my hood?
That will depend on your vehicle’s design and characteristics but it is not uncommon for a pick-up truck to mount the filter in the front of the truck bed behind the driver. In fact, many mount the Frantz engine oil, fuel, and transmission filter units along side each other in that location making for an impressive look and functionally-efficient also. Still others mount the filter in front of the radiator behind the grill or even in the trunk area. With the use of longer fuel hose from the engine to the Frantz Oil Filter it can virtually be mounted almost anywhere. Just remember that the fuel lines and the filter do get hot as the oil flows through them and be careful of moving parts such as fan belts or pulleys.
My car is special. It is a show car. Do you have something for me?
You’re in luck. We have a highly-polished chrome model unit just for you. It will enhance the best looking engines for show. When you pop that hood your friends will ask “what is that cool-looking unit?” Now you can share the Frantz Oil Filter story and tell them where to get their own – right here from me of course. They will appreciate it and so will I.
My car is also so special that I use synthetic oil. Will the Frantz Oil Filter work with synthetic oil?
Absolutely! Many of our customers have an extreme care of their engine operation and use synthetic oil. The Frantz Oil Filter works excellent with all kinds of oil products.
What is a Sandwich Adapter and how is it used with the Frantz Oil Filter?
A Sandwich Adapter is a machined metal insert that is installed or sandwiched between your car's stock spin-on oil filter and the engine block where the oil filter screws onto. It may be used to tap into the car engine's oil pressure for sampling to the Frantz Oil Filter for continuous filtering of your oil instead of installing a "T" fitting at the oil sending unit to acquire the oil pressure source.
What is this oil return line Swivel Fitting I have been hearing about?
When installing your Frantz Oil Filter you may wish to have the oil filter return line go to the oil filler cap and with the use of the swivel fitting, the oil is returned to the engine through the oil filler cap. This is a specially-designed fitting which will still allow you to turn the oil filler cap without twisting or kinking the return oil line. This is a Frantz Oil Filter optional accessory but often is well worth it when trying to find a return path for your clean oil.
