Detailed Description

The WIX 51391 oil filter is engineered for conventional, synthetic, and synthetic-blended motor oils when used according to the vehicle manufacturer’s service schedule. WIX recommends this filter for OEM oil and filter change intervals, typically 3,750 to 10,000 miles and not to exceed 12 months. In severe driving conditions such as stop-and-go traffic, dirt roads, construction sites, short trips, and interstate travel, the filter’s capacity and efficiency help manage contaminants collected during service.

This part cross-references FRAM PH9342 and Purolator L 22821 for the same application. The WIX 51391 is a practical choice for Suzuki Grand Vitara oil filter replacement, Suzuki XL-7 oil filter service, Chevrolet Tracker oil filter replacement, and Suzuki Vitara maintenance.

What It Helps Address

• Engine wear caused by circulating dirt and contaminants
• Dry starts after the vehicle sits between oil changes
• Reduced filtration performance during severe driving cycles
• Routine maintenance needs for scheduled oil service
• Contaminant buildup in engines using conventional or synthetic oil

Installation Notes and Tips

Verify the thread size, gasket sealing surface, and filter dimensions before installation. Replace the filter during each oil service and follow the OE-recommended oil change interval for the vehicle. Confirm the application by year, make, and model before ordering, especially for 1999-2008 Suzuki Grand Vitara, 2002-2006 Suzuki XL-7, 2001-2004 Chevrolet Tracker, and 2004 Suzuki Vitara.
