Several years ago it was stated that they manufacture oil filters for OEM Motorcraft, OEM GM on some applications, AC, Valvoline, AutoZone and the Mobil 1 filter. is a private label supplier for over 30 different automotive and heavy duty filter lines.
A manufacturer may actually make different brands of oil filters, all with different brand labels. We will take a look at a number of brands available today to help you choose what will be your best. With so many brands available today, it can be a challenge to find the best oil filter. Did they test their filter? Are the results that bad they don’t want to share? Too many unknowns for us. Meaning we don’t know the efficiency of how well it traps dirt that is smaller than 20 microns.Īny manufacturer that doesn’t share at least some details as to the efficiency rating on their filters leaves us looking elsewhere. In this case, they can catch 95% of any particle 20 microns or larger.
They claim it to be 95% efficient and the fine print for that fact is as follows:įRAM Group testing of average filter efficiency of PH8A, 3387A and 4967 or equivalent FRAM TG or XG models under ISO 4548-12 for particles greater than 20 microns.įRAM is listing the testing details and the micron size for that rating. Take FRAM’s Extra Guard oil filter for example. Look for the fine print that matches and you will usually find what they are basing that rating on. So when you see manufacturers advertising 95% filtration efficiency, what does that really mean? If you look close enough, most of those statements will always have a little asterisk or symbol at the end. Oil filters are usually not going to catch 100% of the foreign particles in oil. Dirt comes in all sorts and sizes and you want a filter that traps as much as possible. The oil filter’s only purpose is filtering out foreign particles in motor oil.
