If you want a versatile, dual-size plier set that handles everything from compact car filters to PVC plumbing jobs, choose WORKPRO Oil Filter Wrench; if you need a heavy-duty, single-purpose swivel tool specifically engineered for large trucks, RVs, and industrial engines in tight spaces, choose Spurtar Oil Filter Wrench.
• WORKPRO: Offers unmatched versatility with a 2-piece set (9" and 12") and adjustable jaws for small-to-medium filters, but lacks the specialized swivel mechanism needed for deep, obstructed engine bays.
• Spurtar: Delivers superior reach and leverage in confined areas thanks to its 180-degree swivel handle and robust stainless steel band, yet it is limited to one specific large size range and cannot handle smaller filters.
• Who it's for: The WORKPRO set is the ideal choice for general mechanics and DIYers who need one tool to cover a wide variety of filter sizes and occasional plumbing tasks.
• Who it's for: The Spurtar wrench is the definitive pick for professional mechanic shops working on full-size trucks, SUVs, and heavy machinery where clearance is tight and filter diameters are massive.
The WORKPRO Oil Filter Wrench Set stands out because it refuses to be a one-trick pony. This isn't just a single tool; it is a two-piece system comprising a 9-inch and a 12-inch wrench, giving you immediate options depending on the job at hand. Whether you are pulling an oil filter off a standard sedan or wrestling with a slightly larger canister on a light truck, having both lengths in your kit means you aren't forced to overreach or struggle with insufficient leverage. The design philosophy here is clearly about adaptability.
What makes this set particularly compelling for a busy workshop is the 5-position slip joint. The ability to adjust the jaws allows the user to fine-tune the grip for different diameters. The 12-inch model spans from 2-1/2 to 3-3/4 inches, while the 9-inch version covers 1-3/4 to 3 inches. This range captures the vast majority of passenger vehicles and many motorcycles. Furthermore, the angled gripping teeth are designed to bite into surfaces in either direction, which reduces the frustration of slipping when you encounter a slippery, oil-covered filter.
However, this tool has a clear limitation: it is not built for extreme confinement. While the extended handles offer good reach, they lack the flexibility to navigate around obstructions like frame rails or exhaust pipes. If you are working in a tight bay where you cannot get a straight line on the filter, these rigid pliers might not fit. Additionally, because they are carbon steel with a gray phosphate finish, they are durable but rely entirely on the mechanical strength of the slip joint rather than a swiveling mechanism.
This product is perfect for the mechanic shop that sees a high volume of diverse vehicles—sedans, small SUVs, and light trucks—and also needs a tool that can double as a pipe wrench for minor plumbing or assembly tasks. It is also excellent for the serious DIYer who wants a comprehensive solution without buying three or four different single-use tools. If your work involves a mix of automotive maintenance and general repairs, the WORKPRO set provides the breadth of capability you need.

The Spurtar Large Oil Filter Wrench takes a completely different approach, prioritizing raw power and accessibility over versatility. This is a single-purpose instrument designed specifically for the toughest environments. The defining feature is the flexible 180-degree swivel handle. In the real world, this is a game-changer. When you are under a vehicle with limited overhead clearance or facing an oil filter buried behind other components, a rigid wrench simply won't work. The swivel head allows you to position the handle out of the way while still applying torque directly to the filter band.
Durability is another core pillar of the Spurtar design. Constructed from stainless steel with reinforced joints, this tool is built to withstand the corrosion and grime of heavy-duty environments. It targets a specific niche: large vehicles. This puts it squarely in the territory of full-size trucks, vans, RVs, construction equipment, and industrial generators. You will not find this tool suitable for a compact car, but for anything bigger, it offers a level of security and ease that smaller pliers cannot match.
The soft PVC handle adds a layer of comfort that is often overlooked in heavy-duty tools. Removing a stubborn, seized oil filter requires significant force, and the anti-slip grip ensures that your hands do not slide off when you apply maximum pressure. This reduces fatigue during long shifts in a professional shop. The color scheme of red and silver also helps the tool stand out in a cluttered toolbox, making it easy to locate when time is of the essence.
However, you must accept the trade-off: this tool does nothing else. It cannot handle smaller filters, and it has no "slip joint" adjustment beyond its fixed swivel range. It is a specialized weapon for a specific type of battle. Therefore, this wrench is best suited for the professional mechanic shop that specializes in fleet maintenance, heavy trucks, or commercial machinery where the vehicles are large and the filters are notoriously difficult to reach.
• Best for versatility → WORKPRO Oil Filter Wrench: Its dual-size design (9" and 12") and adjustable jaws allow it to handle a broad spectrum of filter diameters, plus it doubles as a pipe wrench.
• Best for tight spaces → Spurtar Oil Filter Wrench: The 180-degree swivel handle is the only feature that truly matters when clearance is restricted by engine components or chassis parts.
• Best for heavy-duty applications → Spurtar Oil Filter Wrench: Designed specifically for large filters (4-9/16" to 5-1/4") found on trucks, RVs, and industrial engines, offering a more secure hold on massive units.
• Best value for mixed fleets → WORKPRO Oil Filter Wrench: One purchase gives you two tools covering small to medium sizes, eliminating the need for multiple single-size wrenches.
• Best for durability in harsh conditions → Spurtar Oil Filter Wrench: Stainless steel construction and reinforced joints offer superior resistance to corrosion compared to the carbon steel used in the WORKPRO set.
• Best for general DIY → WORKPRO Oil Filter Wrench: Most home garages deal with passenger cars and light trucks, making the adjustable range of the WORKPRO set far more practical than the fixed large size of the Spurtar.
• Best for professional fleet shops → Spurtar Oil Filter Wrench: If your daily workflow involves changing filters on large commercial vehicles, the speed and leverage provided by the swivel mechanism save valuable time.
• Best for multi-tasking → WORKPRO Oil Filter Wrench: The inclusion of PVC pipe fitting capabilities makes it a true utility tool for any shop environment.
In my opinion, I would buy the WORKPRO Oil Filter Wrench Set for my personal garage and a general repair shop because its adaptability covers 90% of what most people encounter. However, for a professional mechanic shop dedicated to large vehicles, heavy-duty equipment, and commercial fleets, I would strictly recommend the Spurtar Oil Filter Wrench. The swivel handle solves the most common pain point in automotive repair: lack of space. If you work on big rigs or RVs, the WORKPRO set will eventually feel too small and too rigid. You need the leverage and reach of the Spurtar to keep your workflow efficient and your back safe.
No, the WORKPRO 12-inch wrench maxes out at 3-3/4 inches, which is too small for the large filters (4-9/16" to 5-1/4") typically found on trucks and RVs that the Spurtar handles.
It is not adjustable like the WORKPRO slip-joint pliers, so it will not fit smaller passenger car filters.
The Spurtar Oil Filter Wrench is superior for wet or corrosive environments because it is made from stainless steel, whereas the WORKPRO uses carbon steel with a phosphate finish.
If your shop services a mix of small cars and large trucks, yes. Many professional mechanic shops keep the WORKPRO set for sedans and the Spurtar wrench exclusively for their heavy-duty fleet.
