Abstract

A lubrication system having an oil filter modified to replace or supplement the performance of lubricant additives that may be used within an internal combustion engine to increase the performance of a lubricant is described. Oil filter is a chemical filter that includes filtration media (24) which includes particles(30) including an internal pores (32) formed within individual particles and interstitial pores (34) formed between adjacent particles (30) wherein the internal pores (32) and the interstitial pores (34) collectively define filtration media pores and a strong base material is associated with at least some of the internal pores (32). The filtration media (24) has a surface area greater than or equal to 25 square meters per gram that is derived from filtration media pores that are large enough to receive a combustion acid-weak base complex contained within oil flowing through the chemical filter.
