This was taken off of "oil guard" and if you look at there filters its a tightly woven "string" just like the OE fuel filters for the deuce. There very hard to find the Old stock string ones but they work.
Filter Element Replacement Cost – Yes a roll of toilet paper or a roll of paper towels is cheaper than an OilGuard element. But these items were not designed or manufactured to be oil filters. You wouldn’t use a high quality OilGuard element to dry off your hands or take care of your bathroom business, and there is no reason why you should use a common roll of paper towels or toilet paper to filter your oil and protect your expensive engine.
The filtration engineering and quality standards that go into every OilGuard filter made, are not even considered by the manufactures of toilet paper and paper towels. The paper quality is not intended to hold up to the combination of heat, pressure and loading of oil contamination.
Why OilGuard is Superior:
OilGuard provides a specifically engineered system of filtration and filter elements that were designed for the task of filtering oil to 1 micron.
OilGuard's patented element is guaranteed to deliver both reliability and performance at a cost lower than many other types of bypass filters. Each size is priced dramatically less than elements used by other types of bypass filters.
Problems with Commercially Available
Toilet Paper or Paper Towel Rolls Bypass Filters
This category is suseptible to each of the above problems. Additionally, tissue manufacturers DO NOT design these rolls with the necessary tension and dimensional control required to be a filter. Simply put, it is not recommended to utilize a product for something other than its original purpose.
The paper quality is not intended to hold up to the combination of heat, pressure and loading of oil contamination.
