Attention: TDR Forum Junkies Hello, this is Deborah. I wanted to clarify something to Mr. Park, and to all the other fine readers of this web page. The purpose of the Frantz Oil Cleaner/Filter is to Clean your Oil!
Once the oil in your engine system is cleaned, the Frantz will continue to keep it clean. 
Technically, the Frantz Units were originally invented as an Oil Cleaner. By keeping the oil in your engine system clean all of the time, the wear and tear on your engine is reduced, because the dirt, soot, particulates and water are removed from your oil. It has been a known fact that there are four functions your oil is supposed to provide for your engine.
The 1st function is to Seal. Oil Seals, by creating a seal between the moving piston rings and the cylinder walls and also between the valve stems and the valve guides. This sealing action keeps the oil out of the combustion chamber and the products of combustion out of the oil. The better the seal, the more power is transmitted to your crankshaft, and the greater the engine's efficiency becomes.
The 2nd function is to Cool. Temperatures in the combustion chamber range between 2,000 degrees F. and 3,000 degrees F. The water in the engine block carries away much of this heat, but if it were not for the oil which cools the cylinder walls and the pistons, yourengine would run red hot and ultimately not function at all. In addition to cooling the cylinders and pistons, it carries heat away from the bearings, valves and other moving parts of the engine.
The 3rd function is to Clean. One of oil's basic functions is to keep your engine clean. Carbon deposits are constantly being formed on cylinder walls (this build-up can be much more rapid in improperly tuned or poorly functioning engines). The piston rings which move on a thin film of oil, tend to remove these deposits in a squeege-like action just as a wiper blade removes the accumulated road grime from your windshield when it rains. These carbon deposits that are removed fall right back into the oil pan. That is why and how your oil gets dirty and where the theory of needing to change your oil often came from. When you want to wash the dirt out of your clothes, how well do you think they will get cleaned if you use dirty water? NOT! The same theory applies to your engine; if you want to clean the carbon from the cylinder walls of your engine you will get better results from using clean oil for 2,000-3,000 miles than by using dirty oil. Clean oil will remove the carbon and dirt better than dirty oil will, it's just plain common sense!
The 4th and final function of the oil is to Lubricate. Maintaining proper lubrication is important for the efficient operation of an internal combustion engine. Oil as a lubricant decreases the power required to overcome friction and reduces wear between rubbing and bearing surfaces. Proper lubrication results in increased power and longer engine life. In theory, if oil were kept 100% clean, and if adequate oil pressure were maintained at all times, there would always be a thin film of oil between the bearings and journals; and with no contaminants present, there would be nothing to cause wear.
Of all the physical and chemical properties that an oil may have, it is generally agreed that the characteristic called viscosity is the most important. All other things being equal, it is the viscosity that determines the friction loss, heat generation, mechanicalefficiency, load carrying capacity, film thickness, lubricant flow and in many cases wear. The viscosity of an oil is a measure of its fluid resistence to flow and is regarded as its internal or fluid friction. The degree of contamination can be an important determinant of viscosity and can adversely affect the lubricating properties of oil.
ONLY CLEAN OIL CAN PROPERLY PERFORM THESE FOUR VITAL FUNCTIONS!
All automotive and lubrication authorities agree that clean oil performs these functions better than dirty oil. That's the primary reason for filtering engine oil... to keep it clean. You can do so continuously by installing a Frantz Oil Cleaner/Filter on every vehicle you own or plan to own!
