Choosing the Right Oil Filter
When choosing an oil filter for your Kohler 25HP engine, consider the following:
- Compatibility: Always cross-reference your engine model with the filter’s compatibility chart. Kohler’s 25HP engines are used in various configurations, so make sure the filter fits your exact model.
- Micron Rating: This indicates the size of particles the filter can trap. A lower micron rating generally means better filtration.
- Anti-Drain Back Valve: This feature prevents oil from draining out of the filter when the engine is off, reducing engine wear during startups.
- Durability: Filters should withstand pressure, heat, and vibration. Heavy-duty materials increase longevity.
- OEM vs Aftermarket: OEM filters are designed by the manufacturer for exact fit and specs, while aftermarket brands may offer cost savings and additional features.

How Often Should You Change the Oil Filter?
Kohler recommends changing the oil and oil filter every 100 hours of operation under normal conditions. However, if the engine operates in dusty, dirty, or hot environments, more frequent changes (every 50 hours) are advisable. Regular maintenance helps:
- Prevent engine sludge
- Improve engine performance
- Extend the life of internal components.
Always pair oil filter changes with high-quality motor oil suitable for your Kohler engine, typically SAE 10W-30 or 10W-40, depending on climate and usage.

FAQs
Do all Kohler engines use the same oil filter?
No, not all Kohler engines use the same oil filter. Kohler produces a wide range of engines, such as the Command, Courage, Confidant, 7000 Series, and more, and the correct oil filter depends on the engine model and horsepower. While some engines may share compatible filters (like the Kohler 52 050 02-S).
Can I use 10W40 in my Kohler engine?
Yes, you can use 10W40 oil in your Kohler engine if it’s recommended in your engine’s operating manual. Kohler typically recommends SAE 10W30 for most environments, but SAE 10W40 is acceptable in high-temperature conditions.

How do I figure out which oil filter I need?
To determine the correct oil filter for your Kohler engine:
- Check the engine model number, usually found on a label or plate on the engine shroud.
- Refer to the owner’s manual, and the correct part number for the oil filter will be listed.
- Use Kohler’s parts lookup tool or consult a local dealer, inputting your engine model will show compatible parts.
- Cross-reference with aftermarket brands, once you know the OEM part number (e.g., 52 050 02-S), you can find compatible alternatives from brands like WIX, Fram, or Stens.
What is the difference between yellow and black Kohler oil filters?
The color of the oil filter (yellow vs. black) is primarily a cosmetic or production variation and doesn’t indicate a functional difference. However:
- Both typically share the same part number and performance specs.
- Some yellow filters are used in retail-packaged or extended-life versions.
- Always match by part number, not just color.
So, if two filters have the same number (e.g., 52 050 02-S), they are functionally equivalent regardless of color.
Are Kohler oil filters any good?
Yes, Kohler oil filters are high-quality and OEM-approved for use with their engines. They are designed to:
- Provide proper filtration for Kohler’s high-performance engines
- Resist pressure, vibration, and heat
- Include anti-drain back valves for cold-start protection
- Extend engine life and improve performance
While aftermarket options exist, many users prefer OEM Kohler filters for their guaranteed fit, quality assurance, and warranty compliance.
Final Thoughts
Keeping your Kohler 25HP engine running smoothly depends heavily on choosing and maintaining a high-quality oil filter. Whether you go with the OEM Kohler 52 050 02-S or opt for high-performance alternatives like WIX or Fram, regular filter changes are essential for maximizing the lifespan and reliability of your engine.
