The model number of an oil filter can usually be found on the filter housing, which typically includes the manufacturer's part number. Alternatively, you can refer to the vehicle's manual. An oil filter, also known as an oil element, comes in two main types: full-flow and bypass. The full-flow filter is connected in series between the oil pump and the main oil passage, filtering all the lubricating oil entering the main passage. The bypass filter, on the other hand, is connected in parallel with the main oil passage and only filters a portion of the oil pumped by the oil pump. Structurally, oil filters can be categorized into replaceable, spin-on, and centrifugal types. The filtering materials used include filter paper, felt, metal mesh, and non-woven fabric. A high-quality oil filter should possess strong filtering capability, low flow resistance, and a long service life.
