Wix 51056 Oil Filter for Small Engines — Compatible with Briggs & Stratton, Silicone Anti-Drainback, High-Capacity

WIX 51056 is a premium oil filter engineered to protect small engines and lawn-equipment motors when using synthetic or high-mileage oils.

Designed for a range of small engines including Briggs & Stratton, Hatz, Kawasaki, Kohler and Lister, the WIX 51056 combines a high-capacity filter element with a silicone anti-drainback valve and blended media to keep oil cleaner, longer. It’s built to handle the heavier contaminant loads and extended service intervals that come with modern synthetic and high-mileage oil formulations, so your mower, compact tractor or generator runs more reliably between changes.

How does the WIX 51056 improve protection for small engines?

The 51056 uses an advanced synthetic-blend media that captures very fine particles, helping prevent abrasive wear on bearings and other moving parts. A high-capacity design traps more debris before flow restriction occurs, supporting consistent oil circulation during extended use.

• 99% dirt-trapping efficiency at 26 microns (media performance measured on comparable WIX test models)
• High-capacity pleated element holds more contaminants
• Durable construction resists collapse under pressure

Will this filter work with synthetic or high-mileage oils and longer service intervals?

Yes — the 51056 is formulated to perform with synthetic and high-mileage motor oils, supporting longer drain intervals when recommended by the oil and engine manufacturer. Its media and structural design help sustain filtration efficiency over extended mileage or run-time between changes.

• Compatible with synthetic and high-mileage oil formulations
• Engineered for extended service life up to manufacturer-recommended intervals
• Meets or exceeds original equipment filter standards

How does the silicone anti-drainback valve help during startup?

The built-in silicone anti-drainback valve prevents oil from draining out of the filter when the engine is turned off, maintaining oil at the filter and passages. That reduces the risk of a brief oil-starved start and the extra wear that can follow cold starts or infrequent use.

• Prevents dry starts by retaining oil in the filter
• Silicone material resists heat and aging for reliable function
• Improves protection after idle periods or storage

Which engines and equipment are compatible with the WIX 51056?

The 51056 is commonly used on a range of lawn, garden and small-tractor engines from well-known manufacturers. Always confirm fitment with your machine’s parts list or by using a fitment lookup before purchase to ensure correct threads, gasket size and filtration capacity.

• Compatible with many Briggs & Stratton, Hatz, Kawasaki, Kohler, and Lister small engines
• Suitable for lawn mowers, compact tractors, generators, and other garden equipment
• Verify fitment using your model/year or the manufacturer part finder

Who is this for: The WIX 51056 is aimed at owners and technicians who maintain lawn and garden equipment, compact tractors, or small stationary engines and who prefer synthetic or high-mileage oils and longer service intervals. If you value stronger particulate capture, reliable anti-drainback performance, and a filter that meets or exceeds OEM standards, this model is a practical choice for routine maintenance and heavy-use scenarios.
