1. How often do I need to clean my filter?

The service cycle for your Trufilter is dependent on many facators. But we recommend that you change your oil at 1,500 miles for the first oil change. This is because the Trufilter product removes many of the particles that were left behind by your previous filter. After the initial oil change we suggest you change your oil at 3,000 miles and evaluate the oil for contamients. If the filter has collected a lot of material, stay with 3,000 mile intervals until the filter is reletively clean. Then add 1,500 miles to each cycle until your oil begins to degrade or your filter has collected a reasonable amount of contaminents.

2. How can I get replacement parts?

Our resellers carry replacement filter elements and o-rings for Trufilter products. Contact one of our resellers for parts. You can find a list of our resellers by click the main menu item "Where to Buy" on our home page.

3. Is the technology proven?

This technology has been in use for many years and has proven itself in NASCAR, Formula One racing and the Aerospace industry. These filters have been in use in the off road motorcycle and off road racing world for over 5 years. This is not a new  idea, just a new application of proven technology. And of course, we run these filters on our personal cars, truck, boats, bikes, street and dirt.

4. What materials are used in Trufilter products?

The filter housing and filter element end caps are carved out of a solid chunk of 6061T6 billet aluminum, which not only looks trick but aids in dissipating heat. The filter element is made from laser cut, medical grade, type 304 stainless steel micron filter cloth to provide unmatched protection against oil contamination and resultant engine damage.  The adhesive used in the filter assembly process is good to 600 degrees Fahrenheit, far above the normal operating temperature of 180 to 230 degrees. The Viton ® gasket doubles the seal between the filter housing and the engine.

5. How does this type of filter compare to paper filters?

Testing has show how paper filters handle the smallest and largest sized particles that would pass through the material. We sent the material off with no names, just numbers for identification so the lab wouldn’t have any idea who’s filter they were testing. The results we got back showed that the smallest particle the three would catch ranged between 9 and 20 microns. The LARGEST particle the three would allow to pass through the material ranged from 56 to 300+ microns. Paper filters are rated on an average of what they will let pass, so each of these three would each be rated at numbers that are somewhere between their individual extremes. The medical grade stainless steel cloth that we use is rated at an absolute 30 microns, meaning nothing larger than 30 microns should pass through the material. This “absolute” rating is important because this type of filter material is also used in medical applications like blood filtration. Bottom line is paper is rated differently than the stainless cloth (average vs. absolute), and either one works to filter stuff out of your oil. Personally I like the idea of keeping the big stuff out of the engine.

6. What is a micron?

A micron is one thousandth of a millimeter. That’s approx. .00003937 inches. 35 microns is about .00138“, (just over one-thousandth of an inch). The lower limit of visibility to the human eye is about 40 microns. Pollens range from about 30 to 50 microns. A white blood cell is about 25 microns.
