Using a standard wrench or your hands can result in slipping, damage to the filter, or even injury. An oil filter wrench solves this problem by providing a firm grip and leverage, making the removal and installation process faster, safer, and more efficient.
There are several types of oil filter wrenches, including strap or chain wrenches, cap wrenches, claw wrenches, plier-style, and adjustable jaw types. Each type is suited for different filter sizes and working-space constraints.

What to Look for in a Lawn Mower Oil Filter Wrench
When selecting a wrench for your mower’s oil filter, consider the following factors:
- Compatibility / Size Range – Ensure the wrench fits the diameter of your mower’s oil filter. Most small-engine filters range from approximately 1.9 to 5.1 inches, but it’s best to check your mower’s manual.
- Type of Wrench – Strap or chain wrenches are versatile and good for awkward spaces, while cap wrenches suit filters with knurling. Adjustable-jaw or plier-style wrenches provide more leverage.
- Durability and Build Quality – A strong metal or alloy construction ensures long-lasting performance and makes it easier to remove tight filters.
- Ease of Use in Confined Spaces – Compact or adjustable designs are useful for filters located in tight areas on your mower.
- Value and Versatility – If you maintain multiple machines, a universal or adjustable wrench set can be more cost-effective and practical over time.

How to Use an Oil Filter Wrench Safely on Your Lawn Mower
- Check Your Mower’s Manual – Confirm the filter size, type, and recommended replacement interval.
- Warm Up, Then Cool the Engine – Running the engine briefly helps loosen debris. Turn it off and allow it to cool before starting maintenance.
- Drain Old Oil – Remove the drain plug and collect the old oil in a suitable container to prevent spills.
- Attach the Wrench – Depending on the type of wrench, attach it securely around the filter or place a cap over it. Turn counterclockwise to loosen.
- Remove the Filter Carefully – Unscrew by hand once loose, drain remaining oil, and clean the mounting surface. Lightly coat the gasket on the new filter with fresh oil, then install it by hand, tightening as recommended.
- Refill with Fresh Oil – Add the correct type and amount of oil as specified for your mower. Check for leaks after running the engine briefly and dispose of the old oil and filter responsibly.
Why an Oil Filter Wrench is Worth the Investment
Many lawn mower owners overlook oil filter replacement, focusing only on blade maintenance or oil checks. However, a clogged or dirty filter restricts oil flow, causing poor lubrication, increased friction, overheating, premature wear, and potential engine damage.
An oil filter wrench makes this essential maintenance task quick, clean, and safe. Whether you mow occasionally or operate a landscaping business, using the right tool saves time, prevents injuries, and helps maintain your mower’s engine performance.
Given their affordability and frequent use, investing in a high-quality oil filter wrench is a small cost for long-term savings in engine longevity and reliability.

FAQs
What can I use instead of an oil filter wrench?
If you don’t have an oil filter wrench, you can use a strap, chain, or adjustable pliers to grip the filter. In some cases, a large rubber jar opener or a piece of sturdy rubber hose wrapped around the filter can provide enough friction to turn it. However, these alternatives may require more effort and carry a higher risk of slipping.
How to remove lawn mower oil filter without wrench?
To remove a lawn mower oil filter without a wrench, you can try the following:
- Use a rubber glove or a piece of cloth for extra grip and twist by hand.
- Wrap a sturdy rubber strap or old belt around the filter for leverage.
- For filters with a flat edge, use adjustable pliers carefully, taking care not to crush the filter.
- Always ensure the engine is off and cool, and drain the oil first to avoid spills.
How to know what size oil filter wrench to get?
Check the diameter of your lawn mower’s oil filter, which is usually listed in the mower’s manual. Most small-engine filters range from about 1.9 inches to 5.1 inches. If you plan to service multiple engines, an adjustable or universal wrench that covers a wide size range is often the most practical option.
Do you really need an oil filter wrench?
While it’s possible to remove some filters by hand, an oil filter wrench makes the process much easier and safer. Filters can be tightly installed and coated in oil, which makes them slippery and hard to turn. Using a wrench reduces the risk of injury, damage to the filter, or spilling oil.
How to make a DIY oil filter wrench?
A DIY oil filter wrench can be made using simple household items:
- Rubber strap or old belt – Wrap around the filter and twist to loosen.
- Plywood or strong metal plate – Cut to size and bend into a loop for leverage.
- Bungee cord – Loop around the filter, tighten, and twist carefully.
- DIY methods work best for occasional use, but a proper oil filter wrench is safer and more durable for repeated maintenance.
Final Thoughts
If you perform your own lawn mower maintenance, an oil filter wrench is an essential tool. It simplifies oil changes, reduces the risk of damage, and ensures proper engine protection. From universal adjustable pliers to mower-specific wrenches, there are options to suit different needs and budgets. Using the right wrench allows you to maintain your mower efficiently, keeping it running smoothly season after season.
