Expert Reviews

What experts liked

Stands out due to its low profile design, which means it is very compact and therefore, it fits easily around oil filters even if there is little clearance. This makes it one of the best oil filter wrench for tight spaces.
Features an adjustable oil filter wrench that has a patented 3-jaw design. This feature makes it very easy for its user to remove oil filters. It also has a universal design and it works on almost all passenger and SUV oil filters. It should be noted that a wide range of oil filter sizes could be removed from 1 and 1/2-inch to 4-inch filters.
The low-profile design also helps you to get into low clearance areas. Simply attach this wrench to any 3/8” or 1/2” drive ratchet for easy use. You could also utilize a breaker bar if that’s easiest; just connect it with the adaptor included in the package.
The adaptable spider wrench by Neiko is optimal if you don’t have much clearance to maneuver other tools around in. It’s capable of grasping diameters from 2.5 to four inches. This makes it compatible with the majority of standard passenger vehicles.

What experts didn't like

Driving ratchet, wrench or bar not included.
Made of low-quality materials. Might not be able to fully grip the oil filter.
A few users experienced difficulty accessing recessed units. For removal only.


Since oil filters are greasy, they can be difficult to remove without the proper tools. An oil filter wrench is a must-have, as it is able to provide a tight grip, even if the filter is oily. Whether you’re a professional mechanic looking to add an oil filter wrench to your tool collection or someone who enjoys doing their own vehicle maintenance, you’ll want to keep the following features in mind as you shop.

Check that the oil filter wrench is comfortable to hold. Some models come with rubber handles that allow for a good grip, while others have handles that are textured. You’ll also find models, like the Lisle 57030 Standard Oil Filter Swivel Wrench, that swivel a full 180 degrees. That allows for getting the tool into those hard-to-reach spaces.

Review which size filters the oil filter wrench is able to remove. It is possible to purchase a set with a small wrench that works on filters up to 4 inches in diameter and a large wrench that is able to accommodate filters of up to 6 3/8 inches in diameter. Other wrenches are made using a universal design that works on most passenger car and SUV oil filters.

Look for an oil filter wrench that is built to be tough and durable. For example, the Motivx Tools Oil Filter Wrench is constructed from a high-quality 6061 T5 aluminum that won’t crack under pressure. Other wrenches are made from stainless steel, which is known for its ability to resist rust.

Determine if the oil filter wrench comes with any extra features that make it a better buy. Some options come with an adapter that allows you to use them with any 3/8- or 1/2-inch drive ratchet or breaker bar. There are also models that are completely waterproof.
