How does the 15400-PLC-004 oil Filter improve fuel efficiency?
Dual-valve configuration prevents abnormal fuel consumption
Bypass valve (opening pressure: 1.0 bar): When the filter element is severely clogged after long-term use or oil viscosity spikes at low temperatures, the valve opens in time. This allows unfiltered oil to enter the lubrication system temporarily, preventing dry friction (a major cause of sudden fuel consumption surges) due to insufficient oil supply.
Anti-drainback valve: When the engine is shut down, this valve seals to prevent oil in the filter from flowing back into the oil pan. This keeps the filter filled with oil, enabling the engine to build up oil pressure quickly during restart and reducing fuel waste caused by dry friction in the start-up phase.
