puraDYN™ Filter Technologies has introduced the Model PFT60, the next generation of its by-pass oil filtration system. According to the company, the new filters allow engines to run for hundreds of thousands of miles without the need for a traditional oil change. puraDYN users report that they have seen a 90% reduction in the need for new oil and for oil disposal. By continually removing contaminants and replacing vital additives through its patented time-release additive package, puraDYN filters can substantially increase oil change intervals.
