Detailed Description

Built under the Wix name, part number 51311 is engineered for service intervals commonly specified by the OE vehicle manufacturer, including normal and severe driving conditions such as stop-and-go traffic, short trips, dirt roads, construction zones, and highway use. The filter media is designed to trap contaminants efficiently while maintaining flow, and the flexible silicone anti-drain back valve helps protect against dry engine starts when the vehicle sits between oil changes. This part cross-references FRAM PH2800 and NAPA Gold Filters 1311 for the same application.

Installation Notes and Tips

Verify the thread size, gasket sealing surface, and filter clearance before installation. Replace the filter during the oil service interval specified for the vehicle, and pre-fill only when the engine and service procedure allow it. For Volvo 850, 940, 960, S70, S80, V70, V90, and C70 applications, confirm the exact model year and OE service recommendation before ordering.
