How does the 15201Z9010 oil filter improve fuel efficiency?
Engineered for the ZD30’s high oil flow demands, the 15201-Z9010 has a large filtration surface area + streamlined internal flow channels with a pressure drop of <0.2 bar at rated flow. A restrictive filter forces the engine’s oil pump to work harder, consuming precious engine power (and diesel fuel) just to circulate oil (called parasitic loss). This filter’s low restriction lets the oil pump operate at minimal load, directing more engine torque to vehicle propulsion (towing/hauling) instead of internal mechanical effort — a direct fuel saver for diesel engines with fixed parasitic losses.
