An oil filter will extend the life of your oil resulting in less frequent need to change your oil. This saves money, time, and precious oil resources.
The beginning of the oil filter as we know it began in 1923 by the American inventors Ernest Sweetland and George H. Greenhalgh. It was called Purolator for "Pure Oil Later".
Types of Oil Filters
Mechanical - Mechanical filter uses a material to physically filter the oil using some type of filter element.
Magnetic - Use a magnet to capture ferromagnetic particles.
Sedimentation - contaminants are heavier than the oil, so they settle towards the bottom of a container.
Centrifugal - Uses a spinning force to sepearate the contaminants from the oil.
This is an example of the common screw in mechanical filter.
All modern oil filters use an anti-drain back valve.
