How does the H35WK01 oil Filter improve fuel efficiency?
H35WK01 oil filters are equipped with an anti - drain back valve. This valve can prevent engine oil from flowing back to the oil pan when the engine is shut down, ensuring that the engine components are pre - lubricated when the engine is restarted. This reduces dry friction, minimizes engine wear during startup, and helps the engine reach its optimal operating state more quickly, thereby indirectly improving fuel efficiency.
