O'Reilly oil filters are sold at O'Reilly Auto Parts stores and online, and they come in different types depending on your vehicle's engine and maintenance schedule

O'Reilly Auto Parts carries several lines of oil filters under their own brand, plus filters from other manufacturers. The O'Reilly brand filters themselves come in standard, synthetic, and high-mileage versions. Which one you need depends on what your vehicle's owner manual says and what type of oil you're using — if you run synthetic oil, you want a filter rated for synthetic; if your engine has over 75,000 miles, a high-mileage filter may help with seal conditioning.

O'Reilly filters are made to fit specific vehicle models, so you'll need your vehicle's year, make, model, and engine size to find the right one. You can look this up on O'Reilly's website, call a store, or bring your vehicle information in person. The price varies by filter type and vehicle, but O'Reilly filters generally cost less than OEM (original equipment manufacturer) filters from the car maker.

Key Takeaways

  • O'Reilly oil filters come in standard, synthetic, and high-mileage formulas, and you choose based on your vehicle manual and the oil type you use.
  • You need your vehicle's year, make, model, and engine size to find the correct filter, since filters are vehicle-specific.
  • O'Reilly filters cost less than OEM filters but are designed to meet the same performance standards.
  • O'Reilly stores can help you locate the right filter in person or by phone if you're unsure which one fits your vehicle.

Standard vs. synthetic vs. high-mileage O'Reilly filters

A standard O'Reilly filter works with conventional mineral oil and is replaced every 3,000 to 5,000 miles, depending on your vehicle and driving conditions. These are the most affordable option and work well for vehicles on regular oil change schedules.

A synthetic O'Reilly filter is designed to work with synthetic motor oil, which lasts longer than conventional oil. Synthetic filters have media that can handle the higher temperatures and longer intervals of synthetic oil — typically 7,500 to 10,000 miles or more. If you use synthetic oil but put a standard filter on your vehicle, the filter may clog before the oil needs changing.

High-mileage O'Reilly filters are made for engines over 75,000 miles and include additives meant to condition seals and reduce oil leaks in older engines. These cost more than standard filters but may help prevent leaks that develop as engines age. Check your owner manual to see if your vehicle manufacturer recommends a high-mileage filter.

How to find the right O'Reilly filter for your vehicle

Start by gathering your vehicle's information: the year, make, model, and engine size. You can find engine size in your owner manual or on a sticker under the hood. O'Reilly's website has a filter finder tool where you enter this information and it shows you compatible filters.

If you're shopping in a store, bring your vehicle keys or a photo of your registration — staff can look up the correct filter using your vehicle identification number (VIN), which is printed on your registration and visible on the driver's side of the windshield. You can also call your local O'Reilly store with this information and they'll tell you which filters are in stock.

Once you know the filter model number, you can compare prices between O'Reilly's website and in-store, and check whether the store has it in stock or can order it for you.

O'Reilly filter pricing and where to buy

O'Reilly oil filters range in price depending on the type and vehicle. Standard filters typically cost between $5 and $15, synthetic filters between $8 and $20, and high-mileage filters between $10 and $25. Prices vary by location and current promotions, so check O'Reilly's website or call a store for the exact price of the filter you need.

You can buy O'Reilly filters at any O'Reilly Auto Parts store, on their website with in-store pickup or home delivery, or through third-party retailers that stock O'Reilly brand products. Some people buy the filter from O'Reilly and install it themselves, while others purchase it and have a mechanic or quick-lube shop install it during an oil change.

What to check before you buy

Confirm the filter's part number matches your vehicle. O'Reilly's system will show you the correct part number once you enter your vehicle information, so write it down or take a photo before you go to the store or order online.

Check the filter's thread size and diameter to make sure it physically fits your engine. The product description on O'Reilly's website includes these measurements. If you're unsure, ask an O'Reilly employee to verify the fit before you buy.

Look at the filter's bypass valve rating, which tells you at what pressure the filter will allow unfiltered oil to flow if the filter gets too clogged. This is listed in the product specs and should match your vehicle manufacturer's recommendation — O'Reilly filters are designed to meet these standards, but it's worth confirming if you're switching from another brand.

Installing an O'Reilly filter yourself

If you change your own oil, installing the filter is straightforward. Locate the filter on your engine (usually a cylindrical canister on the side), use a filter wrench to unscrew the old one, and screw the new one on by hand until the rubber gasket on top touches the mounting surface, then turn it an additional three-quarter turn. Do not over-tighten, as this can damage the gasket and cause leaks.

Before you install the new filter, fill it about three-quarters full with fresh oil from the new oil you're putting in your engine. This primes the filter so it doesn't starve the engine of oil when you first start it. Wipe the mounting surface clean with a rag to remove any old gasket material or debris.

After installation, start your engine and let it run for a minute, then turn it off and wait five minutes for the oil to settle. Check the oil level on your dipstick and top off if needed. If you see any leaks around the filter, turn off the engine and tighten it slightly — but only slightly, as over-tightening is the most common cause of leaks.

Frequently Asked Questions

Can I use an O'Reilly filter with a different brand of oil?

Yes. O'Reilly filters work with any brand of oil, as long as you match the filter type to the oil type. Use a standard filter with conventional oil, a synthetic filter with synthetic oil, and a high-mileage filter if your engine is over 75,000 miles. The filter brand and oil brand don't have to match.

How often should I replace an O'Reilly oil filter?

Replace it every time you change your oil. With conventional oil, that's usually every 3,000 to 5,000 miles; with synthetic oil, every 7,500 to 10,000 miles or more. Check your owner manual for your vehicle's specific interval, as it varies by engine and driving conditions.

What's the difference between an O'Reilly filter and an OEM filter?

OEM filters come from your vehicle's manufacturer and are often more expensive. O'Reilly filters are made to meet the same performance standards and fit the same way, but cost less. Both are designed to protect your engine equally well if you choose the correct type for your vehicle.

Do O'Reilly filters come with a warranty?

O'Reilly brand filters typically come with a limited warranty covering defects in materials or workmanship. Check the product packaging or ask an O'Reilly employee for the specific warranty terms, as they can vary by filter type and location.

Can I return an O'Reilly filter if it doesn't fit?

Yes, O'Reilly has a return policy for unopened filters. If you open the filter or install it, return policies vary by store location. Keep your receipt and bring the filter back to the store where you bought it to discuss your options.
