The job of the Lexus RX350 Oil Filter is to protect the engine by trapping dirt and metal particles while maintaining a constant flow of oil. Built around cellulose, synthetic, or blended media, this Oil Filter is up to 99 percent efficiency as contaminants are trapped for thousands of miles before capacity is reached. Two filtration systems make up the bulk of RX350 history, a full flow design which flushes all of the lubricant through the element for instant bearing protection and a bypass route that polishes oil for additional cleanliness for longer drain intervals. Early versions of the RX350 applied disposable spin-on units, while later versions of the RX350 adopted the replaceable cartridge style that reduces the amount of waste while withstanding the high pressures a modern Lexus V6 can develop, and both styles incorporate pressure relief and anti-drainback valves as integral parts of the Oil Filter assembly to prevent oil starvation at startup and rupture under high load conditions. Every Lexus owner must know that a clean Oil Filter ensures the viscosity remains stable, the sludge is less, and ensures the smooth operations that come with the Lexus, hence keeping the Oil Filter serviced on time is important.
