AMSOIL Oil Filters feature advanced, full-synthetic media that traps and holds a greater amount of small, wear-causing contaminants compared to conventional filters. They provide extended service intervals for increased convenience while helping reduce engine wear.
AMSOIL Oil Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 99% at 20 microns – one of the best ratings on the market. Some competitors also claim 99% efficiency, but at larger particle sizes of 30 to 40 microns.
