Finding the correct oil filter for your Briggs and Stratton engine requires understanding the complex web of part numbers and cross-references. This guide cuts through the confusion, providing specific details to help you identify the right filter for your machine. Whether you are a seasoned mechanic or a homeowner tackling routine maintenance, knowing the exact specifications prevents leaks and ensures optimal engine performance.
Why Accurate Oil Filter Identification Matters
Using the wrong oil filter on a Briggs and Stratton engine can lead to premature engine wear or catastrophic failure. An incorrect filter may have the wrong media, poor gasket sealing, or inadequate bypass pressure settings. These issues restrict oil flow or allow unfiltered contaminants to circulate, directly impacting the longevity of your equipment. Proper identification based on the engine model is the single most important step in maintenance.
Primary Reference by Engine Model
The most reliable method for determining the correct oil filter is to look at the engine identification tag. This tag, usually located on the shroud or near the recoil starter, contains the specific model number. You can use this number to consult the original equipment manufacturer (OEM) parts list, which lists the exact factory-fitted filter part number. Below is a table outlining common engine models and their factory filter specifications.

Decoding Aftermarket Brand Names
Aftermarket brands like Fram, WIX, and Purolator often produce filters that match the OEM specifications exactly, but are sold under different part numbers. These companies typically manufacture the filter for Briggs and Stratton and apply their own branding. When searching for a replacement, look for the dimensions and micron rating on the packaging to ensure compatibility. The table above provides the most common aftermarket equivalents for the factory parts.
Understanding Micron Ratings and Oil Capacity
Beyond the part number, two technical specifications are critical for engine health: micron rating and oil capacity. The micron rating indicates the size of debris the filter can capture; a rating of 10 to 30 microns is standard for small engines, balancing filtration with flow. Furthermore, the oil capacity of your engine dictates the size of the filter. You can find the oil capacity in the engine manual, and the filter must hold enough media to contain the recommended amount of oil without causing pressure issues.
Where to Verify and Purchase
When in doubt, the best resource is the Briggs and Stratton parts website. Enter your engine model number into their configurator to pull up the official parts breakdown, including the oil filter. Local small engine repair shops also maintain extensive cross-reference databases. These professionals can often identify the correct filter by the engine serial number alone, saving you the guesswork of comparing part numbers at the store.
