Finding your Purolator oil filter starts with your vehicle's year, make, and model

Purolator makes oil filters for most vehicles on the road, but the filter that fits your car is not the same as the one for your truck or your neighbor's sedan. The easiest way to find the correct filter is to use Purolator's online filter finder tool on their website, where you enter your vehicle information and get back the exact part number you need. You can also look up the filter by checking your owner's manual, calling a parts store with your vehicle details, or reading the part number off your current filter if you are replacing one.

The filter you need depends on your engine size, the year your vehicle was made, and sometimes the transmission type. A 2015 Honda Civic takes a different filter than a 2015 Ford F-150, even though they are the same model year. Purolator's lookup system accounts for all these variables so you do not end up with a filter that does not fit or does not seal properly.

Key Takeaways

  • Purolator's online filter finder at purolator.com lets you search by year, make, model, and engine size to find your exact part number.
  • Your vehicle's owner's manual lists the correct filter part number and cross-references it to Purolator's catalog.
  • Auto parts stores can look up your filter by vehicle information without you having to search yourself.
  • The part number on your current filter tells you what Purolator filter is compatible with your vehicle.
  • Purolator filters come in different grades and capacities, so matching the exact part number ensures proper fit and oil flow.

Using Purolator's online filter finder tool

Purolator's website has a dedicated filter lookup page where you select your vehicle's year, make, and model from dropdown menus. After you choose those three pieces of information, the tool shows you the correct part number, the filter type (standard or synthetic), and sometimes a photo of the filter so you can see what you are ordering. The page also lists where to buy that specific filter, including Purolator's own online store and major retailers.

The tool is free to use and does not require you to create an account or enter personal information. You can bookmark the page or write down your part number for future reference. If you have multiple vehicles, you can run the lookup for each one and keep a list in your phone or car.

Reading your current filter's part number

If you already have an oil filter in your vehicle, the part number is printed on the side or top of the filter itself. The number usually starts with letters followed by numbers—for example, PL14610 or PL51000. You can use this part number to order a replacement directly without running a lookup, since the same part number means the same filter will fit.

This method works only if you are replacing a Purolator filter with another Purolator filter. If your vehicle currently has a different brand of filter, you will need to use the online lookup tool or check your owner's manual to find the Purolator equivalent.

Checking your owner's manual for the filter specification

Your vehicle's owner's manual lists the correct oil filter part number in the maintenance section, usually near the oil capacity and viscosity grade. The manual may list the original equipment manufacturer (OEM) filter—the brand that came on your vehicle from the factory—but it also cross-references Purolator and other aftermarket brands. Look for a section titled "Recommended Fluids and Capacities" or "Maintenance Schedule."

If you do not have a physical copy of your manual, you can read a PDF from the manufacturer's website or search for your vehicle's manual on free sites like ManualsLib. Having the manual on hand is useful because it also tells you the correct oil viscosity and how often to change the filter, which affects which Purolator product you should buy.

Asking a parts store to look up your filter

Auto parts retailers like AutoZone, O'Reilly, NAPA, and Advance Auto Parts can look up your filter for you at the counter or over the phone. You give them your vehicle's year, make, model, and engine size, and they tell you the Purolator part number and show you the filter in stock. Many stores will also install the filter for a small fee if you buy it from them.

This approach is useful if you want to see the filter in person before buying or if you want installation help. Some stores offer this lookup service over the phone, so you can call ahead and have the part number ready before you visit.

Understanding Purolator filter types and part number variations

Purolator makes several lines of filters under different brand names and quality levels. The PL series is their standard line, the PureOne line is their mid-range synthetic option, and the Boss line is their heavy-duty option for trucks and commercial vehicles. The part number tells you which line the filter belongs to, so PL14610 is different from PL51000 even though both are Purolator filters.

The correct part number for your vehicle is specific to that line. If your owner's manual or the online lookup tool says you need a PL14610, you cannot substitute a different Purolator part number and expect it to fit. The diameter, thread size, and internal bypass valve are engineered for your engine, and using the wrong filter can cause oil pressure problems or leaks.

Where to buy Purolator filters after you have the part number

Once you know your part number, you can buy the filter from Purolator's official website, Amazon, Walmart, Target, auto parts chains, or local independent shops. Prices vary by retailer and by filter type—synthetic filters cost more than standard filters. Buying online often costs less than buying in-store, but you have to wait for shipping unless you choose in-store pickup.

Some retailers offer bulk discounts if you buy multiple filters at once, which makes sense if you have several vehicles or plan to change your oil regularly. Checking prices across a few retailers before buying can save you money, especially on synthetic filters where the price difference between stores can be significant.

Frequently Asked Questions

What if my vehicle is very old or very new and does not show up in the Purolator lookup tool?

Older vehicles may not be in the online database, but calling Purolator's customer service line or visiting a parts store with your vehicle information can still get you an answer. For very new vehicles, the lookup tool is usually updated within a few months of the model year release. If your vehicle is not yet in the system, a parts store can often cross-reference your OEM filter to find the Purolator equivalent.

Can I use a different Purolator part number if the one recommended is out of stock?

No. Each part number is designed for a specific engine, and substituting a different Purolator filter can cause fit or performance problems. If your part number is out of stock, order it online for delivery, check other retailers, or ask the store when they expect it back in stock. Using the wrong filter is not worth the risk of oil leaks or engine damage.

Does the Purolator filter part number change if I switch from conventional to synthetic oil?

The part number stays the same. The filter itself is the same whether you use conventional or synthetic oil—the difference is in the oil, not the filter. However, Purolator makes synthetic-specific filters under the PureOne line that may have a different part number, so check the lookup tool to see if your vehicle has a synthetic option if you want one.

What if I have an engine swap or a non-standard engine in my vehicle?

The Purolator lookup tool works only for factory engines. If your vehicle has a different engine than it came with, you need to know the year, make, and model of the engine itself, not the vehicle. Use that engine information in the lookup tool, or bring the engine details to a parts store and they can cross-reference it for you.
