Fram Xg10575 Ultra Spin-on Oil Filter on 2040-parts.com

FRAM ULTRA Oil Filters feature dual layer synthetic media reinforced with a durable metal screen to deliver up to 15,000 miles of engine protection. With 99 percent dirt-trapping efficiency, this filter traps and holds more than double the dirt. The silicone anti-drain back valve holds a reserve of oil in the filter to help protect the engine during start-ups. With an ideal balance of dirt-trapping efficiency and dirt-holding capacity, every FRAM oil filter uses filter media with a special blend of fibers and resin providing excellent engine protection. The most commonly used filter media is cellulose, which is a natural material that presents a random and irregular field of fibers to the oil. By itself, it can only deliver about 80 percent dirt-trapping efficiency. By adding microscopic synthetic fibers, small windows are created that trap the smaller dirt particles without affecting the flow of oil. Blending synthetic fibers with cellulose increases a filter's dirt-trapping efficiency and its dirt-holding capacity for higher levels of engine protection and longer filter life.
