Automotive requirements for oil filters:

Filtration accuracy, filter out all particles > 30 um,
Reduce particles that enter lubrication gaps and cause wear (< 3 um - 30 um)
The oil flow corresponds to the oil demand of the engine.
Long change intervals, at least longer than the life of the oil (km, time)
The filtration precision meets the requirements of protecting the engine and reducing wear.
Large ash capacity, suitable for harsh environments.
Can adapt to higher oil temperature and corrosive environment.
The lower the pressure difference when filtering the oil, the better, to ensure that the oil can pass smoothly.
