Using Purolator's Filter Finder to Match Your Vehicle

Purolator publishes a cross-reference chart that matches your vehicle's year, make, and model to the correct filter part number. You can access this chart on Purolator's website or request a printed version at most auto parts retailers. The chart lists filters by vehicle process rather than by filter name, so you need your vehicle's exact year and engine size to find the right one.

Start by locating your vehicle's year, make, and model in the chart's left column. Then move across the row to find your engine size — this matters because the same model year can have multiple engine options, and each requires a different filter. The chart will show you the Purolator part number that fits your vehicle. Write down this number before you go to the store or order online, because part numbers are how retailers look up filters in their systems.

If you cannot find your vehicle in the chart, or if you own an older or less common vehicle, call a Purolator customer service line or visit a local auto parts store with your vehicle information. Staff can cross-reference your vehicle against their database and confirm the correct part number in seconds.

Key Takeaways

  • Purolator's chart matches your vehicle's year, make, model, and engine size to a specific part number you need to purchase.
  • The chart is available online at Purolator's website and in printed form at most auto parts retailers.
  • You must know your engine size to use the chart correctly, because the same vehicle model can have multiple engine options.
  • If your vehicle does not appear in the chart, auto parts store staff can look up the correct filter using their own database systems.

Where to Find the Official Purolator Chart

Purolator maintains a searchable filter chart on its official website. You can enter your vehicle information directly into their online tool, and the system will return the correct part number and filter specifications. This online version is updated regularly as new vehicles are released and is usually faster than flipping through a printed chart.

Most auto parts chains — including AutoZone, O'Reilly, NAPA, and Advance Auto Parts — keep printed Purolator charts behind the counter or in their filter aisles. These printed versions are organized by vehicle make and are free to use in the store. If you prefer to look it up before you leave home, the online chart is your best option.

Reading the Chart: Year, Make, Model, and Engine Size

The chart is organized in columns. The first column lists vehicle makes (Ford, Chevrolet, Toyota, and so on). The second column shows model names (F-150, Silverado, Camry). The third column shows the year or year range the filter fits. The fourth column specifies engine size, usually written as a displacement in liters (2.5L, 5.0L) or sometimes as a number of cylinders.

Engine size is critical because it determines oil flow rate and filter capacity. A 2.5-liter four-cylinder engine needs a different filter than a 5.0-liter V8 in the same model truck, even though both are the same year and make. If you are unsure of your engine size, check your vehicle's owner manual, look at the engine bay (the size is often stamped on the engine block), or ask your mechanic.

Once you locate your vehicle's row in the chart, follow it to the right until you reach the Purolator part number column. This number — typically starting with "PL" or "PUR" — is what you need to order or purchase.

What the Part Number Tells You

A Purolator part number like "PL14610" or "PUR14610" is a unique identifier for a specific filter design. The number encodes the filter's thread size, bypass valve setting, and internal specifications. Two filters with different part numbers will not fit the same engine, even if they look similar.

When you order or purchase a filter, always use the part number from the chart rather than the filter's common name. A parts counter employee can look up the part number in their system and confirm it is in stock, fits your vehicle, and matches what you need. If you order online, entering the part number into the search box will show you the exact filter and its price.

Cross-Referencing with Other Brands

If you want to compare Purolator filters to other brands, most auto parts retailers have their own cross-reference systems. You can tell a parts employee your Purolator part number, and they can show you equivalent filters from Mobil 1, Fram, Bosch, or other manufacturers. This is useful if another brand is on sale or if you prefer a different filter type (synthetic, extended-life, or standard).

Keep in mind that equivalent filters from different brands may have slightly different specifications, even though they fit the same engine. Purolator's chart shows only Purolator products, so if you switch brands, confirm the replacement filter's part number with the new manufacturer's chart or with a parts retailer before you buy.

Handling Older Vehicles and Special Cases

Vehicles older than about 15 years may not appear in current Purolator charts because the manufacturer stops printing entries for discontinued models. If your vehicle is older, call Purolator's customer service line or visit an auto parts store with your vehicle's year, make, model, and engine size. Many older vehicles still have filters available, but you may need to look them up by phone or in person rather than using the printed chart.

Some specialty vehicles — commercial trucks, RVs, marine engines, or equipment — may require filters not listed in the standard automotive chart. Purolator publishes separate charts for these applications. If your vehicle is not standard passenger car or light truck, ask the parts retailer whether a specialty chart exists for your process.

Frequently Asked Questions

What if the chart shows multiple part numbers for my vehicle?

Multiple part numbers usually mean your vehicle came with different engine options in different years or model generations. Find the row that matches your exact year and engine size, then use that part number. If you are still unsure, confirm your engine size with your owner manual or mechanic before ordering.

Can I use a different Purolator filter if my exact part number is out of stock?

No. Each Purolator part number is designed for a specific engine and oil system. Using the wrong part number can result in incorrect oil flow, bypass valve pressure, or thread size, which can damage your engine. If your part number is out of stock, wait for it to be restocked or contact Purolator to find an authorized equivalent.

Where do I find my vehicle's engine size if it is not in the owner manual?

Engine size is usually stamped on the engine block itself, visible when you open the hood. It appears as a number followed by "L" (for liters). You can also call your vehicle's dealership with your vehicle identification number (VIN), and they will tell you the engine size. A mechanic can also identify it in seconds.

Does the Purolator chart work for diesel engines?

Purolator makes filters for diesel engines, but they are listed in a separate section of the chart or in a dedicated diesel filter guide. Diesel filters are not interchangeable with gasoline engine filters. Confirm your engine type before using the chart, and if you have a diesel vehicle, look for the diesel section or ask a parts retailer for the diesel-specific chart.

Can I order a Purolator filter online using the part number from the chart?

Yes. Once you have the part number from the chart, you can enter it into any auto parts retailer's website, Purolator's own website, or general online retailers. The part number will pull up the exact filter, show you the price, and let you check availability before you order.
