Common Oil Filter Sizes
Most modern oil filters fall into one of several common size ranges:
| Filter Size | Dimensions |
| Small | 2 1/2 to 2 3/4 inches diameter |
| Medium | 3 to 3 1/2 inches diameter |
| Large | 3 3/4 to 4 1/2 inches diameter |
The most common oil filter sizes are the small and medium filters in the 2 1/2 to 3 1/2 inch range. Large truck and specialty vehicle filters can range up to 5 inches or more in diameter.
Oil Filter Wrench Sizes
There are oil filter wrenches made to fit each of these general size ranges:
| Wrench Type | Opening Size |
| Small | 2 1/2 – 3 inches |
| Medium | 3 – 3 1/2 inches |
| Large | 3 1/2 – 4 1/2 inches |
| Extra Large | Over 4 1/2 inches |
The most common are small and medium oil filter wrenches that fit the majority of filters. Large and extra large oil filter wrenches are needed for bigger filters.
Small Oil Filter Wrenches
Small oil filter wrenches have an opening size ranging from about 2 1/2 to 3 inches. This covers most small engine filters such as those used on:
- Compact cars
- Motorcycles
- Lawn mowers
- Outboard motors
- ATVs
- Snow blowers
These small wrench sizes allow access to filters in cramped engine compartments where a larger wrench won’t fit. Sturdy small adjustable filter wrenches are best for getting better grip on small slippery filters.
Medium Oil Filter Wrenches
The medium size oil filter wrenches have an opening ranging from about 3 to 3 1/2 inches. This is suitable for the majority of canister and cartridge type filters used in:
- Most passenger vehicles
- SUVs
- Light trucks
These are by far the most commonly used oil filter wrench sizes. Medium non-adjustable band wrenches or adjustable strap wrenches work well for most oil changes.
Large Oil Filter Wrenches
Large oil filter wrenches have a larger opening of around 3 1/2 to 4 1/2 inches. These are required for the bigger oil filters used in:
- Heavy duty trucks
- Commercial vehicles
- Farm equipment
- Construction equipment
- Some large marine engines
Sturdy adjustable or band type filter wrenches are needed to handle the big, thick filters found in these heavy duty applications.
Extra Large Oil Filter Wrenches
Extra large oil filter wrenches have openings exceeding 4 1/2 inches for the monster oil filters on things like:
- Over-the-road semi trucks
- Busses
- Industrial generators
- Heavy equipment
These oversize filters require an extra large filter wrench to grab hold of the big outer housing. Large adjustable wrenches or giant band wrenches are made specifically for these huge oil filters.
Choosing the Correct Size Oil Filter Wrench
– For small filters under 3 inches diameter, use a small 2 1/2 to 3 inch oil filter wrench
– For most common canister and spin-on filters, a medium 3 to 3 1/2 inch oil filter wrench works best
– Big filters over 3 1/2 inches need a large or extra large oil filter wrench of equal size
– Adjustable oil filter wrenches allow flexibility to fit a range of sizes
– Sturdy band type oil filter wrenches also work well on a variety of filter sizes
– Compare your filter size to the oil filter wrench opening to make sure they match
– Consider space constraints when choosing standard or low-profile filter wrench types
Selecting the properly fitting oil filter wrench makes removing and installing oil filters quicker, easier and damage-free. Always verify wrench size to match your particular application.
Specialty Oil Filter Wrench Types
Beyond the standard adjustable and band wrenches, there are also some specialty oil filter wrench designs:
Low-Profile Oil Filter Wrenches
Low-profile oil filter wrenches have a thin, flat design that can reach filters in tight engine compartments. Common types include:
– Thin profile band wrenches
– Low-clearance cup wrenches
– Short-handled adjustable strap wrenches
These minimized filter wrenches are made to access hard-to-reach oil filters.
Ratcheting Oil Filter Wrenches
Ratcheting oil filter wrenches use geared mechanisms to get added turning leverage on stubborn filters. The ratcheting design also allows working in tight spaces.
Oil Filter Pliers
Oil filter pliers have adjustable gripping jaws that firmly clamp onto the filter for removal. These give tremendous grabbing and turning power for the toughest stuck filters.
Powered Oil Filter Wrenches
Powered oil filter wrenches use pneumatic, electric or cordless power to automatically spin off tightly sealed filters. Popular types are air impact wrenches and high torque cordless filter wrenches. These make quick work of even the most difficult oil changes.
Oil Filter Cutter Tools
Oil filter cutter tools are used to saw open the oil filter if it is too tight to unscrew. This allows draining the trapped oil inside before prying the filter off. A long approaches for removing hopelessly stuck filters.
Tips for Using an Oil Filter Wrench
– Clean area around the oil filter and pre-lubricate the filter gasket with fresh oil prior to installation for easier removal next time.
– Take care not to overtighten the new oil filter more than necessary.
– Position the wrench on the filter and turn counterclockwise to break the seal then unthread the filter.
– An initial rocking motion helps break the seal before unscrewing.
– Adjustable wrenches allow clamping the jaws tightly around the filter for a solid grip.
– Ratcheting oil filter wrenches provide added leverage for stubborn filters.
– Avoid low quality thin metal band type wrenches that can flex and slip.
– Be patient with difficult to remove filters rather than damaging the engine with excessive force.
