I’ve struggled with oil filters tucked in tight engine bays, where a standard strap wrench just won’t fit. That’s exactly why I wanted to test the OEMTOOLS 25320 Oil Filter Wrench Pliers. Its 20° angled jaw and adjustable slip joint are designed for those cramped spots.
This tool is really for the home mechanic or DIYer doing their own oil changes. The forged steel construction gives it solid grip strength, but its slip-joint design means it’s not a one-size-fits-all solution for every filter type. Here’s what I found after putting it to work on a few of my cars.

What Stands Out — Key Features
- Wide Adjustable Range: The slip joint lets you fit filters from 2-1/2″ to 4-5/8″ (63.5 mm to 117.5 mm). I found this covered every standard filter on my cars and light truck.
- Forged Steel Jaws: These heavy-duty alloy steel jaws don’t flex. When you’re cranking on a stubborn filter, you can feel the solid strength and it inspires confidence.
- 20° Angled Jaw Design: This bend is the real hero. It gave me the extra clearance I needed to get a good grip on a filter that was tucked right next to a frame rail.
- Non-Slip Teeth: The teeth on the jaws bite into the filter canister well. I noticed they held firm, even when the filter was a bit oily.
- Cushioned Vinyl Handles: The vinyl-dipped grips are comfortable and provide good slip resistance. My hands didn’t feel sore after wrestling with a tight filter.
- Compact and Durable Build: At just over 1 pound, it feels substantial without being clumsy. The overall construction feels like it will last for years in a home garage.
- Simple Slip-Joint Operation: Adjusting the size is quick and intuitive. You just slide the joint to the notch that gives you the best grip on your specific filter.

Pros & Cons — The Honest Take
✅ What I Like
- The 20° angled jaw genuinely improves access to filters in cramped engine bays.
- Forged steel jaws feel incredibly strong and don’t flex, even on the tightest filters.
- The wide 2-1/2″ to 4-5/8″ adjustment range fits most common automotive and light truck filters.
- Vinyl-dipped handles are comfortable and provide a secure, non-slip grip.
- The simple slip-joint design makes adjusting for different filter sizes quick and easy.
❌ What Could Be Better
- On very smooth or rounded filters, the jaws can slip before they bite in, requiring perfect adjustment.
- It’s a specific tool; for filters in wide-open spaces, a standard socket-style wrench might be faster.
For me, the pros heavily outweigh the cons. This tool solved a real access problem I had, and its build quality is solid. Just know it might take a couple of tries to get the perfect grip on a slick filter.
⚖️ How Does It Compare?
When looking at the OEMTOOLS 25320, I see two main types of competitors: other adjustable pliers and different wrench styles. I picked these two because they represent the most common alternatives you’ll find when shopping for a filter tool.

🔵 Alternative 1: HORUSDY 12″ Adjustable Oil Filter Pliers
Best for: Someone who wants a very similar tool, often at a slightly lower price point.
Key specs: 12-inch length, adjustable slip joint, check listing for exact jaw capacity.
Where it beats the main product: It’s often priced a bit lower, making it a tempting budget-friendly option.
Where it falls short: The build quality and jaw strength may not feel as Solid as the OEMTOOLS forged steel.

⚪ Alternative 2: MateAuto Oil Filter Wrench
Best for: DIYers who prefer a cap-style wrench that fits on a ratchet for maximum torque.
Key specs: Multi-size cap set (e.g., 65mm-67mm, 74mm), 3/8″ drive, steel construction.
Where it beats the main product: It provides a more positive, non-slip grip on filters that match its specific cap sizes.
Where it falls short: It’s not one tool; it’s a set of specific sizes, so it won’t fit the full 2-1/2″ to 4-5/8″ range as easily.
If you’re on a tight budget and your filters aren’t notoriously stuck, the HORUSDY is a decent gamble. However, I’d choose the MateAuto cap set only if you know your vehicles use a couple of specific filter sizes and you have good access for a ratchet. For the universal 2-1/2″ to 4-5/8″ range and proven strength in tight spots, the OEMTOOLS pliers are my pick.
How It Actually Performs
Grip Strength & Jaw Integrity
The forged steel jaws are the real deal. I used these on a filter that was on way too tight, and I was impressed that the jaws didn’t flex or spread at all. They provide a very solid, direct bite. The non-slip teeth dug in well, but on a perfectly smooth, rounded filter canister, I did experience a bit of slippage before I adjusted the slip joint to the perfect notch for maximum pressure.
Access in Tight Spaces
This is where the 20° jaw bend earns its keep. On my compact car, the filter is tucked right next to a coolant line. The angled design let me get the pliers onto the filter body where a straight tool simply wouldn’t fit. The 4.63-inch cutting width is compact enough to maneuver in a crowded engine bay, making it live up to its claim of working in confined spaces.
Adjustability & Fit
The slip joint handle works simply and effectively. Sliding it through its range, I could easily adjust to grip filters across the advertised 2-1/2″ to 4-5/8″ spectrum. It secured firmly on a common 3-inch filter and opened wide enough for a larger truck filter. The adjustment isn’t infinite—it clicks into set positions—but the range covered every standard size I encountered.
Comfort & Control During Use
The vinyl-dipped handles make a noticeable difference. When you’re applying serious force, the cushioned grip prevents hot spots on your palms. At 1.05 pounds, the tool has a good heft for Use without being fatiguing. The grip stayed secure even when my hands were a bit greasy, which is a common reality during an oil change.
Who Should Buy This Generator?
Not every tool is right for every person. Based on my testing, here’s who will get the most value from this wrench and who might be better served by something different.
✅ This Is a Great Fit If You…
- Are a DIYer who changes oil on your own cars, SUV, or light truck and need a reliable, go-to tool.
- Frequently encounter filters in cramped engine bays where the 20° angled jaw provides crucial access.
- Want a single tool that can handle a wide range of filter sizes, from 2-1/2″ to 4-5/8″.
- Value durable construction and don’t mind paying a bit more for forged steel that won’t flex under pressure.
❌ You Might Want to Look Elsewhere If…
- You work exclusively on equipment with filters in wide-open spaces; a standard cap wrench on a ratchet would be faster.
- You need to remove filters that are extremely smooth and rounded, where a strap-style wrench might grip better.
- You’re looking for the absolute cheapest possible tool and are willing to compromise on jaw strength and long-term durability.
My top recommendation is for the home mechanic who does their own maintenance and has been frustrated by filters in tight spots. The OEMTOOLS 25320 solves that specific problem very effectively with solid build quality.

Common Issues & Fixes
Even a good tool can have hiccups. Here are a few problems I ran into or can foresee, and how I solved them.
Jaws Slipping on a Smooth Filter
The problem: The pliers slip and can’t get a bite, especially on a slick, rounded filter canister.
My fix: First, make sure the slip joint is adjusted to the tightest notch that still fits over the filter. If it still slips, try wiping the filter and the jaw teeth clean of oil with a rag to improve grip.
Not Enough Clearance to Open the Handles
The problem: The filter is so tucked away that you can’t open the pliers wide enough to get them around it.
My fix: Remember the jaws open independently. You can often slide one jaw into place first, then work the other one around the filter. The 20° bend helps with this angled approach.
Difficulty Loosening a Very Stuck Filter
The problem: You’re applying full force, but the filter just won’t budge.
My fix: Ensure the jaws are gripping the very base of the filter, closest to the engine block, for maximum Use. You can also try tapping the end of the handle with a rubber mallet to help shock it loose.
Handle Adjustment Feels Stiff
The problem: The slip joint mechanism is hard to slide to adjust the size.
My fix: A drop of light machine oil on the pivot point and sliding surfaces works wonders. Wipe off any excess to keep it from attracting dirt.
Warranty & Support
The product listing directs you to click a link for warranty information, which is fairly standard. For support, your best bet is to go through the seller on Amazon or contact OEMTOOLS directly if you have a manufacturing defect. The Amazon return policy can be helpful if you receive a faulty tool.

Frequently Asked Questions
What size oil filters will this wrench fit?
It’s designed to fit filters from 2-1/2 inches to 4-5/8 inches in diameter (63.5 mm to 117.5 mm). I found this covers the vast majority of filters on cars, SUVs, and light trucks. It won’t fit tiny filters on some lawn equipment or massive ones on heavy machinery, but for standard automotive use, it’s got you covered.
Will it work on filters that are really stuck on?
Yes, the forged steel jaws are built for this. They resist flexing, so you can apply a lot of torque. The non-slip teeth help, but if the filter is extremely tight and has a smooth surface, you might need to adjust the slip joint to the perfect notch and ensure you’re gripping at the very base. I’ve used it on some stubborn ones with good success.
Is the 20-degree bend really that helpful?
In my experience, absolutely. That slight angle provides just enough offset to get the jaws onto a filter that’s tucked right next to a component. It doesn’t seem like much on the bench, but in a cramped engine bay, it’s often the difference between getting a grip and not being able to fit the tool in at all.
What’s the difference between this and a cap-style wrench?
A cap wrench is a specific socket that fits one or a few filter sizes and goes on a ratchet. This plier is adjustable for a whole range of sizes. The cap style gives a more positive grip if you have the right size and good access. This plier is the versatile choice for multiple vehicles and tight spaces, making it a great value for a home garage that works on different cars.
Are the handles comfortable?
The vinyl-dipped cushions are a nice feature. They’re not super squishy, but they provide a comfortable, non-slip grip that reduces hand strain. When you’re really cranking on a filter, you’ll appreciate not having bare metal handles digging into your palms.
Can I use this to tighten a new filter?
I wouldn’t recommend it. These are removal tools designed for high torque. For installing a new filter, you should hand-tighten it as specified by the manufacturer (usually 3/4 to 1 turn after the gasket makes contact). Using these pliers risks over-tightening and damaging the new filter or its seal.
My Final Verdict
After testing it on several vehicles, I can confidently say the OEMTOOLS 25320 Oil Filter Wrench Pliers is a well-made, effective tool. The forged steel jaws and 20° bend deliver on their promises for strength and access in tight spaces. I’d strongly recommend it to any DIYer or home mechanic who needs a reliable, adjustable tool for standard 2-1/2″ to 4-5/8″ filters. I wouldn’t choose it for someone who only works on equipment with wide-open filter access or who needs to grip perfectly smooth, rounded cans.
The main limitation is that the slip-joint grip can slip on slick filters before it bites. However, for the vast majority of common oil changes, its versatility and durable construction make it a tool you’ll grab for every time. It solves a specific, frustrating problem very well.
