Must-Have Tools in Your House If You Work Regularly
Changing your car’s oil is a fundamental part of keeping it running smoothly. It’s a task many car owners can tackle themselves, saving money and gaining valuable experience. However, one of the trickiest parts of this process can be removing the old oil filter. It’s often stuck tight, and without the right tool, it can turn a simple job into a greasy, frustrating ordeal. Don’t worry, though! We’re here to guide you through the world of oil filter wrenches. We’ll explore the different types available, helping you find the perfect one to make your next oil change a breeze.
Understanding Different Types of Oil Filter Wrenches
The oil filter is a vital component of your engine, trapping contaminants and keeping your oil clean. When it’s time for a replacement, you’ll need a specialized tool to grip and turn that often stubborn filter. Fortunately, there are several effective oil filter wrenches designed for this specific job, each with its own advantages. Knowing these different types of oil filter wrenches is the first step to mastering your DIY oil changes.
Why You Need the Right Oil Filter Wrench
Imagine this: you’ve got all your supplies ready for an oil change – fresh oil, a new filter, a drain pan, gloves – and then you encounter the old oil filter. It’s on there TIGHT. Trying to twist it off with just your hands is usually futile, and using pliers can damage the filter housing, leading to messy oil spills and potential cuts from sharp metal edges. This is where an oil filter wrench becomes your best friend. It provides the leverage and grip needed to loosen even the most stubborn filters safely and efficiently. Using the correct wrench not only saves you time and frustration but also prevents damage to your engine or other components.
The Most Common Types of Oil Filter Wrenches
Let’s dive into the most popular and effective types of oil filter wrenches you’ll encounter. Each has a unique design to tackle the challenge of removing an oil filter, and understanding their differences will help you choose the best one for your needs and your car’s specific filter.
1. Oil Filter Pliers (or Adjustable Oil Filter Pliers)
These are perhaps the most recognizable and widely used oil filter wrenches. They resemble a pair of large pliers with curved, toothed jaws designed to grip the cylindrical body of the oil filter. The handles are long, providing good leverage.
- How they work: You position the jaws around the filter, squeeze the handles, and turn. Many have an adjustable jaw opening to accommodate various filter sizes.
- Pros: Easy to use, readily available, generally inexpensive, good leverage.
- Cons: Can sometimes crush the filter if not used carefully, might not fit in very tight spaces, teeth can damage the filter housing (though this is usually not a concern as you’re replacing the filter anyway).
- Best for: General use, most common filter sizes, DIYers who need a versatile tool.
2. Oil Filter Strap Wrenches
Strap wrenches use a durable strap (often rubber, fabric, or metal) that wraps around the oil filter. The strap tightens as you turn the wrench, providing a secure grip.
- How they work: You loop the strap around the filter and then use the handle to turn. The strap cinches down, gripping the filter.
- Pros: Excellent grip, less likely to crush the filter than pliers, can work on filters in slightly awkward positions, good for various filter diameters.
- Cons: May require more effort to position the strap correctly, some rubber straps can slip if greasy.
- Best for: Filters that are difficult to access, users who prefer a gentler grip on the filter, a wide range of filter sizes.
3. Oil Filter Cap Wrenches (or Socket-Style Wrenches)
These are specialized sockets designed to fit specifically over the end of the oil filter. They have a hexagonal or multi-sided shape that matches the fluting on the end of many oil filters. They attach to a ratchet or breaker bar.
- How they work: You slide the cap wrench over the end of the oil filter and then use a ratchet or breaker bar to turn it.
- Pros: Provides a very secure grip, minimizes the risk of crushing the filter, excellent for tight spaces where pliers or straps might not fit, very efficient.
- Cons: You need the correct size cap for your specific filter (which can be a downside if you work on multiple vehicles with different filters), can be more expensive than basic pliers.
- Best for: Precision work, mechanics who know the filter sizes they commonly encounter, tight engine bays.
Tip: Many automotive parts stores offer oil filter wrench sets that include several common cap sizes, or they can help you find the exact cap for your vehicle.
4. Oil Filter Band Wrenches
Similar to strap wrenches, but they typically use a metal band with a gripping surface. The band wraps around the filter, and a handle allows you to turn it.
- How they work: The metal band tightens around the filter as you apply pressure with the handle.
- Pros: Very strong grip, durable.
- Cons: Can be more prone to crushing the filter than strap wrenches if too much force is applied, can be bulky.
- Best for: Stubborn filters, situations where a very strong grip is needed.
5. Oil Filter Claw Wrenches (or Spider Wrenches)
These tools feature three or four legs that grip the filter. As you turn the wrench, the legs tighten their grip on the filter. Some are spring-loaded for automatic adjustment.
- How they work: The legs automatically adjust to grip the filter as you turn.
- Pros: Versatile for different filter sizes, good grip.
- Cons: Can sometimes slip if the filter surface is very smooth or greasy, might require a bit more space to operate than cap wrenches.
- Best for: Users who want a versatile tool that handles multiple filter sizes without needing to switch attachments.
Choosing the Right Oil Filter Wrench for Your Needs
With so many options, how do you pick the best oil filter wrench? It really depends on your specific situation, the types of vehicles you work on, and your personal preference.
Considerations for Selection:
- Vehicle Type and Filter Accessibility: Do you work on one car, or several? Are the oil filters in your vehicles easily accessible, or are they tucked away in tight spaces? For tight spots, cap wrenches are often superior. For general accessibility, pliers or strap wrenches are excellent.
- Filter Size and Type: While many wrenches are adjustable, some cap wrenches are specific to certain filter diameters. If you know the exact size of your oil filter, a cap wrench can be very efficient.
- Frequency of Use: If you’re a casual DIYer who changes oil a few times a year, a good pair of oil filter pliers or a versatile strap wrench might be all you need. If you’re a professional or a very frequent DIYer, investing in a set of cap wrenches might be more practical.
- Budget: Oil filter wrenches vary in price. Pliers and basic strap wrenches are generally the most affordable, while specialized cap wrench sets can be a larger investment.
- Grip Strength and Comfort: Some wrenches offer more comfortable handles or provide a more secure, non-slip grip.

| Cap Wrenches | Tight spaces, specific filter sizes | Precise fit, no crushing, efficient | Need correct size, can be costly for sets |
| Claw Wrenches | Variable filter sizes, good grip | Automatic adjustment, good grip | Can slip on smooth filters, needs some space |
Getting the Right Size for Cap Wrenches
If you decide a cap wrench is the way to go, getting the right size is crucial. Many oil filters have their diameter stamped on the side, or you can find this information in your vehicle’s owner’s manual. You can also measure the filter itself. Common sizes range from around 60mm to 100mm. Most auto parts stores will have a selection of common sizes, and they often have a lookup tool to find the correct size for your specific vehicle and filter model.
Using Your Oil Filter Wrench Safely and Effectively
Once you’ve got your wrench, using it correctly is key.
Steps for Removal:
- Warm Up the Engine (Slightly): Run the engine for a minute or two. This can help loosen the filter slightly as the oil expands, but don’t let it get too hot to handle safely.
- Position the Drain Pan: Place your drain pan directly under the oil filter. Some oil will inevitably spill when the filter is removed.
- Attach the Wrench:
- Pliers: Position the jaws around the filter and squeeze firmly.
- Strap/Band: Wrap the strap or band around the filter and position the handle.
- Cap Wrench: Slide the cap securely onto the end of the filter. Attach your ratchet or breaker bar.
- Claw Wrench: Position the legs around the filter and engage the mechanism.
- Loosen the Filter: Turn the wrench counter-clockwise (lefty-loosey). Apply steady pressure. If it’s very tight, a longer-handled ratchet or breaker bar can provide more leverage.
- Unscrew by Hand: Once the seal breaks, you should be able to unscrew the filter the rest of the way by hand. Be prepared for residual oil to drain out.
- Dispose of Old Filter Properly: Place the old filter in a plastic bag to prevent leaks and take it to an auto parts store or recycling center for proper disposal.
Installing the New Oil Filter
Installing the new filter is just as important as removing the old one.
- Lubricate the Gasket: Dip your finger in a bit of clean engine oil and spread a thin film over the rubber gasket of the new oil filter. This helps create a good seal and makes removal easier next time.
- Hand-Tighten: Screw the new filter onto the engine block by hand until the gasket makes contact.
- Firmly Tighten: Once the gasket touches, tighten the filter an additional 3/4 to 1 full turn by hand. Most oil filters do not require a wrench for installation. Over-tightening with a wrench can damage the gasket and make removal difficult. Always check the filter manufacturer’s recommendations, which are usually printed on the filter itself.
Why hand-tightening is usually enough: The rubber gasket is designed to compress slightly when the filter is tightened, creating a seal. Overtightening can deform or tear the gasket, leading to leaks. For specific torque requirements, consult your vehicle’s manual or a reliable automotive resource like AutoZone’s guides, which often list torque specifications for common components.
Frequently Asked Questions About Oil Filter Wrenches
We’ve compiled some common questions to help clear up any remaining doubts.
What is the best type of oil filter wrench?
The “best” type depends on your needs. For general DIY use, adjustable oil filter pliers or a strap wrench are excellent starting points due to their versatility and affordability. For mechanics or those working on many different vehicles, a set of cap wrenches is often preferred for precision and ease of use in tight spots.
Can I use regular pliers to remove an oil filter?
While you can try, it’s not recommended. Regular pliers are likely to slip, crush the filter unevenly, and make a mess. They also don’t provide the necessary leverage or grip for stubborn filters. Dedicated oil filter wrenches are designed for the job and will save you frustration and potential damage.
How do I know which size oil filter wrench I need?
If you’re using a cap wrench, you need the specific size that fits the end of your oil filter. Check your vehicle’s owner’s manual, look for markings on the old filter, or consult an auto parts store’s lookup guide. For adjustable wrenches like pliers or strap wrenches, they are designed to fit a range of common filter diameters.
How tight should I tighten a new oil filter?
Most oil filters should be tightened by hand. Once the rubber gasket makes contact with the engine block, tighten it an additional 3/4 to 1 full turn by hand. Always check the instructions printed on the oil filter itself or in your vehicle’s manual, as some specialized filters might have different requirements.
How do I prevent oil from spilling when removing the filter?
Always position your oil drain pan directly beneath the oil filter before you start loosening it. Even with a pan, some residual oil will likely drip out, so it’s a good idea to wear gloves and perhaps keep some shop rags handy for quick cleanups.
Are there any special oil filter wrenches for specific car makes or models?
Yes, some manufacturers or specific engine designs might have oil filters in very unusual or hard-to-reach locations, or with unique filter housing designs. In such cases, specialized oil filter wrenches, sometimes branded for specific makes like BMW, Mercedes-Benz, or Toyota, might be available. These often take the form of specific cap wrenches or oddly shaped tools.
Where can I buy oil filter wrenches?
You can find oil filter wrenches at almost any auto parts store (e.g., AutoZone, Advance Auto Parts, O’Reilly Auto Parts). They are also widely available online through retailers like Amazon, Walmart, and specialized tool websites. Many home improvement stores with automotive sections also carry them.
