FRAM® Extra Guard® oil filters are the number one choice in oil filters among consumers. Oil that lubricates and cools the engine is picked up by the engine's oil pump, cleaned by the oil filter, and reused. It is vital that any dirt or contamination picked up by the circulating oil be removed before it is pumped back into the engine. Tiny dirt particles between 10 and 20 microns do much of the damage to bearings, cylinders and other moving engine parts by rubbing and causing wear. How? FRAM Extra Guard filter uses a thick, multi-fiber media and provides a maze to trap contaminants effectively. Before oil enters the engine lubrication system, it passes through the oil filter. The filter's job is to remove potentially engine-damaging dirt particles. To provide the best engine protection, the maximum amount of dirt should be removed the first time the dirt passes through the filter before it reaches the engine. The Society of Automotive Engineers approved an industry standard test called the "Single Pass Efficiency Test" (SPE) to measure a filter's ability to remove contaminants from the engine's system. The SPE Test is one of the industry standards for evaluating and comparing oil filter performance, and measures a filter's ability to remove less than 20 micron-sized particles of dirt the first time through. The FRAM Extra Guard filter performs at 96. 2% efficiency in the single-pass efficiency tests. And like the FRAM® Tough Guard oil filter, the Extra Guard filter features our advanced synthetic glass and cellulose media, which is a combination of synthetic glass and cellulose uniquely formulated for top-rated efficiency for the life of the filter. SureGRIP® No Slip Finish - More of a Good Thing FRAM® Extra Guard® oil filters only got better when FRAM introduced the new SureGRIP® feature.
