Premium Guard PG4631 Engine Oil Filter

Premium Guard PG4631 Oil Filter Overview

Premium Guard PG4631 is a spin-on engine oil filter built for a wide range of Chevrolet, GMC, Cadillac, Hummer, Ford, and Pontiac applications. It uses enhanced cellulose media, a 15~25 micron rating, and a 25L/min flow rate to support clean oil circulation in engines that rely on this filter size and thread pattern.

The Standard Life line focuses on dependable everyday service for older and late-model truck, van, and SUV applications. PG4631 is a direct replacement choice for many GM V8 and truck platforms, including Chevrolet Silverado 2500, Chevrolet Tahoe, and GMC Yukon applications that call for this filter specification.

Detailed Description

Premium Guard PG4631 is an engine oil filter designed around the standard spin-on format used across many GM truck, van, SUV, and classic car applications. Its enhanced cellulose media balances filtration and oil flow, while the anti-drain back valve helps keep oil in the filter during shutdown so pressure can build more quickly at startup. The bypass relief valve setting of 14-17 supports oil delivery when the filter media becomes restricted, and the NBR gasket is specified for sealing consistency in service.

This part cross-references Wix 51060 and Baldwin B1428 for the same application. It is a strong match for long-tail searches such as oil filter for 2000 Chevrolet Tahoe, oil filter for 1996-2002 GMC Savana 2500, and PG4631 filter for 1988-2000 Chevrolet K3500.

What It Helps Address

• Engine oil contamination from normal wear particles
• Oil pressure delay after engine shutdown and restart
• Restricted oil flow caused by a loaded filter element
• Routine maintenance needs on high-mileage truck and van engines
• Service replacement for vehicles using the 13/16"-16UNF-2B spin-on filter thread

Installation Notes and Tips

Verify the filter thread size, gasket diameter, height, and outer diameter against the removed filter before installation. Clean the mounting surface, lightly lubricate the gasket, and tighten the filter according to the vehicle manufacturer’s service procedure. Confirm that the engine calls for a spin-on filter with this size and bypass specification before use.

Compatible fitment includes 2000-2002 Chevrolet Silverado 2500, 1996-2002 Chevrolet Express 3500, 1992-2000 GMC Yukon, and 2004-2006 Chevrolet Silverado 3500. Additional applications include 1975-2005 Chevrolet P30, 1988-2000 Chevrolet C3500, and 1996-2002 GMC Savana 1500.
