What Walmart carries in oil filter wrenches and where to find them
Walmart stocks oil filter wrenches in the automotive section, typically near the oil and filter supplies rather than with general hand tools. The selection varies by store size and location — larger Supercenters carry more options than smaller neighborhood markets. You will find both cup-style wrenches (the most common type, which grip the filter from the outside) and strap wrenches (which use a fabric or rubber band to grip), priced between roughly $5 and $20 depending on the brand and style.
Walmart's in-store inventory changes, so calling ahead or checking the Walmart app before you visit saves a trip. The app shows real-time stock at your nearest location. If your local store does not have the specific size or type you need, you can order online for pickup or delivery, usually within one to two days.
Key Takeaways
- Cup-style filter wrenches are the most common type at Walmart and work on most vehicles, but you need to know your filter diameter before you buy.
- Strap wrenches cost less and work on any size filter, making them a good choice if you are unsure of your filter size or work on multiple vehicles.
- Walmart's automotive section stocks these tools, but availability varies by store location and size.
- The Walmart app shows which wrenches are in stock at your store right now, saving you from a wasted trip.
Cup-style wrenches: the standard choice for most filters
Cup-style wrenches are the most popular type because they grip the filter firmly and give you good leverage. They come in different diameters — common sizes are 74mm, 76mm, 80mm, 86mm, and 93mm — and you need the right size for your specific filter. If the wrench is too small or too large, it will not grip properly and you risk stripping the filter or damaging the wrench.
To find your filter size, check your vehicle's owner manual or look at the filter itself — the diameter is usually printed on the label. Walmart typically carries the most common sizes (76mm and 86mm cover many vehicles), but less common sizes may require ordering. Cup wrenches usually cost $8 to $15 and last for years if you take care of them.
Strap wrenches: the flexible option when size is uncertain
A strap wrench uses a fabric or rubber band looped around the filter, tightened by pulling a handle. The advantage is that one strap wrench works on any filter size, so you do not need to know the diameter beforehand. This makes strap wrenches useful if you work on different vehicles or are not sure which size you need.
Strap wrenches typically cost $5 to $12 at Walmart and are lighter and easier to store than cup wrenches. The trade-off is that they require more hand strength to use and can slip if the filter is very tight or if your hands are oily. For occasional home oil changes, a strap wrench is often the better choice.
Brands and price ranges you will see at Walmart
Walmart carries several brands of oil filter wrenches, including Craftsman (a mid-range option), Kobalt (Walmart's house brand for tools), and various generic brands. Craftsman wrenches typically run $10 to $18 and are known for durability. Kobalt wrenches are usually $7 to $12 and offer decent quality for the price. Generic or unbranded wrenches may cost $5 to $8 but vary more in build quality.
Price alone does not determine how well a wrench will work — a $6 strap wrench from any of these brands will loosen a filter just as effectively as a $15 cup wrench. The difference shows up over time: cheaper wrenches may bend or crack after several uses, while mid-range brands hold up through dozens of oil changes. For a one-time use or occasional maintenance, the cheapest option works fine. If you change your own oil regularly, spending a few dollars more on a Craftsman or Kobalt wrench is worth it.
How to measure your filter and pick the right wrench
Before you go to Walmart or order online, measure or identify your filter size. The easiest method is to look at your current filter — the diameter is printed on the label or stamped into the metal. Write down the number (it will be in millimeters, like 76mm or 86mm). If you cannot see the filter, check your owner manual under "maintenance" or "oil change specifications."
Once you know the size, search Walmart's website or app for that specific diameter. If you are buying a strap wrench instead, size does not matter — any strap wrench will work. When you are at the store, hold the cup wrench up to the filter (if you brought it with you) or compare the diameter markings on the wrench packaging to your filter size.
Alternatives if Walmart does not have your size in stock
If Walmart's local inventory does not include your filter size, you have several options. Order online through Walmart.com for pickup or delivery — the app will show you estimated arrival dates. You can also check other local retailers like AutoZone, O'Reilly Auto Parts, or NAPA, which often stock a wider range of sizes. A strap wrench from any retailer will work on any filter, so that is always a backup choice if you need the tool when ready.
Some people borrow a wrench from a friend or neighbor rather than buy one for a single use. If you do borrow, return it in the same condition — a wrench that has been bent or damaged is less useful to the owner. If you plan to change your own oil more than once, buying your own wrench is more practical than borrowing repeatedly.
Frequently Asked Questions
How do I know if a cup wrench will fit my filter?
The diameter must match. Look at your filter label or your owner manual to find the size in millimeters. At Walmart, the wrench packaging shows the diameter it fits. If you are unsure, a strap wrench works on any size and costs less than guessing wrong.
Can I use a regular wrench or pliers instead of an oil filter wrench?
Pliers can damage the filter housing and are hard to grip without slipping. A filter wrench is designed to grip the curved surface without denting it. Even a cheap strap wrench from Walmart is safer and easier than improvising with tools not meant for the job.
Do I need to buy the wrench at Walmart, or can I get it elsewhere?
Walmart is one option, but AutoZone, O'Reilly, NAPA, and online retailers like Amazon carry the same brands and sizes. Walmart's prices are competitive, and the app lets you check stock before you go. Choose based on what is in stock near you and how soon you need it.
Will a strap wrench work as well as a cup wrench?
Both work, but differently. A cup wrench gives more leverage and is faster if you know your filter size. A strap wrench requires more hand strength but works on any size and costs less. For most home oil changes, either one is fine.
What if the wrench I buy is the wrong size?
Walmart accepts returns on tools within 90 days with a receipt. If you bought in-store, bring the wrench back to customer service. If you ordered online, start a return through your account. Keep the packaging and receipt to make the return easier.
