Wix Oil Filter 51748 High-Capacity for Cummins & Komatsu Engines — Synthetic/High-Mileage, Silicone Anti-Drainback

The WIX 51748 is a high-capacity oil filter engineered for synthetic and high-mileage oils, built to protect heavy-duty engines including compatible Cummins and Komatsu applications.

The WIX 51748 (shorter version 51741) is a premium replacement oil filter designed for drivers who push their vehicles hard — towing, long-haul highway work, or operating in dusty or stop-and-go conditions. It combines a synthetic-blended media, a silicone anti-drainback valve, and a rugged construction to trap contaminants, reduce wear from dry starts, and support longer service intervals when used with modern motor oils.

How does this filter improve engine protection during heavy use?

The advanced blended filtration media captures very small particles that can accelerate wear, while the filter’s high-capacity design handles higher contaminant loads during demanding duty cycles. That combination helps maintain oil quality and reduces the risk of abrasive damage to internal components.

• 99% efficiency at 26 microns on tested media types
• High-capacity pleats reduce flow restriction under load
• Robust construction for heavy-duty applications

Will this work with synthetic or high-mileage motor oils?

Yes — the WIX 51748 is formulated to be compatible with modern synthetic and high-mileage oils, allowing the filter to perform across extended intervals while retaining contaminant-holding capability. It meets or exceeds many OE expectations for longevity when paired with appropriate oil and service practices.

• Engineered for synthetic and high-mileage formulations
• Designed to support extended service life up to recommended intervals
• Meets or surpasses OE standards for durability

How does the anti-drainback valve protect my engine?

The silicone anti-drainback valve prevents oil from draining out of the filter when the engine is off, preserving oil where it’s needed for immediate lubrication at startup. That reduces metal-to-metal contact during the critical first seconds after ignition, lowering wear from dry starts.

• Silicone valve resists degradation from heat and oil additives
• Maintains residual oil in the filter to prevent dry starts
• Designed for repeated service intervals without loss of function

How do I confirm fitment for my vehicle?

Confirming fitment is simple: use the vehicle part finder or check engine model compatibility lists to ensure the 51748 (or the shorter 51741 reference) matches your engine. Proper fitment avoids leaks, improper sealing, or flow restrictions that can harm performance.

• Enter vehicle year, make, and model into the part finder
• Cross-reference against Cummins and Komatsu compatibility guidance
• Verify gasket size and thread match during installation

Who is this for: The WIX 51748 is aimed at fleet operators, towing enthusiasts, commercial drivers, and owners of Cummins-compatible equipment who want a durable oil filter that works well with synthetic and high-mileage oils. If you need a filter that stands up to towing, extended runs, harsh environments, or longer drain intervals while helping protect engine components, this WIX premium replacement is a practical choice. Always verify fitment for your specific engine and follow recommended oil and service intervals for best results.
