By stating some facts about oil and oil filtration, you will get a better understanding of how the proper combination can work together to protect and prolong the life of your engine and save oil too. The fact that oil itself does not wear out has been clearly established through laboratory oil analysis and by the U.S. Bureau of Standards.
However, three major enemies of oil dirt, moisture, and heat can render the oil useless if left unfiltered. By removing dirt and moisture from the oil and holding it in the filter media, a Roilgard filter element greatly lessens the job needed to be done by the additives. Therefore the additives last much longer.
