Abstract: An oil filter suitable for use in the lubricating oil system of an internal combustion engine, the oil filter element of which has an adherent oxygenated boron derivative. The oxygenated boron derivative can be boric acid and/or any of its dehydration products, salts or esters. The methods of dispersing the oxygenated boron derivative in the oil filter element include (1) accelerating the oxygenated boron derivative toward the oil filter element by maintaining a pressure differential across the oil filter element; (2) sandwiching the oxygenated boron derivative between two layers of oil filter element material; (3) making a solution of the oxygenated boron derivative in a liquid vehicle, soaking the oil filter material with the solution and volatilizing the liquid vehicle from the oil filter element.
