With his filtration model, and filtration unit, dialysis of the entire system was, performed. Contamination from the oil, plus contamination caked in pipes and components immersed in oil was, removed. Removing friction increases the life of components immersed in oil and that of the oil. After filtration, the oil properties stay similar to new oil, and filtered oil becomes cleaner than new oil. Filtered oil does not have to be, discarded for, say, 100 years. Thus, land and air do not get contaminated or polluted.
