Oreillys: How O’Reilly Auto Parts Works, What It Offers, and How to Save

Oreillys

In 1957, a father and son opened a small auto parts store in Springfield, Missouri, with 13 employees. Nearly 70 years later, that business runs more than 6,700 stores across three countries. Most drivers just call it Oreillys, and for many of them it is the first stop when a battery dies, a wiper streaks, or the check engine light comes on.

This guide explains how the company grew, what you can get there beyond parts, how its rewards and return policies work, and how to spend less on your next repair.

Oreillys at a Glance

A Short History

The Family Start

Charles F. O’Reilly and his son, Charles H. “Chub” O’Reilly, opened the first store in Springfield in 1957. Chub had worked for another parts company that wanted to move him to a new city. The family chose to stay and start their own business instead.

From the start, the company served two groups: professional mechanics and people who fix their own cars. That two-sided model still drives the business today.

Going Public and Growing

The company went public in 1993. Through the 1990s and 2000s, it grew by opening new stores and buying regional chains. One of its biggest deals came in 2008, when it bought CSK Auto, which ran chains like Checker, Schuck’s, and Kragen on the West Coast. Those stores were later rebranded under the O’Reilly name.

Expanding Beyond the U.S.

In 2019, the company entered Mexico by buying Mayasa, a parts distributor. In 2024, it moved into Canada by buying Groupe Del Vasto, a Quebec-based business. By late 2026, it had 134 stores in Mexico and 29 in Canada.

How Big Is It Today?

The company keeps growing. In the third quarter of 2026, sales reached $5.12 billion, up 9 percent from a year earlier. Sales at stores open at least a year rose 7.2 percent. The company raised its full-year outlook and expects to open 225 to 235 net new stores in 2026.

Here is how the store count broke down at the end of September 2026:

Part of the reason for steady growth is simple: Americans are keeping their cars longer. Older cars need more repairs, and higher new car prices push more people to fix what they have.

What You Can Buy

Stores carry parts and supplies for nearly every car, truck, and SUV on the road. Common categories include:

• Batteries for cars, trucks, boats, and lawn equipment
• Brakes, including pads, rotors, calipers, and fluid
• Filters for oil, air, cabin air, and fuel
• Fluids like motor oil, coolant, transmission fluid, and washer fluid
• Wipers and lighting, including headlight and tail light bulbs
• Engine parts, from spark plugs to water pumps and alternators
• Accessories, such as floor mats, seat covers, phone mounts, and cleaning products
• Tools and shop equipment

If a store does not have a part on the shelf, it can often get it from a nearby hub store or distribution center, sometimes the same day.

Store Brands vs. Name Brands

Shelves carry national brands and house brands. House brands such as BrakeBest, MicroGard, Super Start, and Import Direct often cost less and come with solid warranties. For many everyday parts, a house brand is a smart way to save. For performance or specialty parts, some drivers prefer name brands.

Free Services Most Drivers Don’t Know About

One of the best reasons to visit Oreillys is the list of free services. Exact offerings can vary by store and state, so call ahead, but most locations offer:

Battery Testing and Charging

Staff can test your battery, starter, and alternator, often right in the parking lot. If your battery is weak, they can charge it. Many stores will also install a new battery you buy there, though some vehicles make this hard.

Check Engine Light Scanning

When your check engine light comes on, the store can read the trouble code with a scan tool. This tells you which system may have a problem. The code does not always name the exact part, but it is a strong starting point. Some states limit this service, so ask your local store.

Loaner Tool Program

Need a special tool for one job? The loaner tool program lets you borrow it. You pay a deposit, use the tool, and get your money back when you return it. This can save you from buying a tool you may only use once.

Wiper and Bulb Help

Many stores will help install wiper blades and some bulbs. Installation help depends on the vehicle and store staff.

Recycling

Stores accept used motor oil, oil filters, batteries, and some other fluids for recycling. Bringing back an old battery can also get you a core credit.

Other Free Services

• Custom hydraulic hoses at some locations
• Rotor and drum resurfacing at some stores, often for a fee
• Parts testing for items like alternators and starters

O’Rewards: The Loyalty Program

The O’Rewards program is free to join. Members earn points on most purchases and get rewards they can use on future buys. Members also get special offers and can track purchases, which helps with warranty claims.

To get the most from the program:

1. Sign up online or in store with your phone number.
2. Give your number at checkout every time.
3. Watch for bonus point offers and member deals.
4. Use rewards before they expire.

Since many drivers visit a parts store several times a year, the points add up.

Returns, Warranties, and Cores

Return Policy

Most new, unused parts in their original packaging can be returned with a receipt within a set time frame. Electrical parts, special orders, and used items may have stricter rules. Keep your receipt or use O’Rewards so the store can look up your purchase.

Warranties

Many parts carry warranties, from 90 days to a limited lifetime. Batteries often have free replacement periods. If a warrantied part fails, bring it back with proof of purchase for a replacement.

Core Charges

Some parts, such as batteries, alternators, starters, and brake calipers, carry a core charge. This is a deposit you get back when you return the old part. It encourages recycling and rebuilding. Always ask about the core charge before you buy so you know what to bring back.

Shopping Online and Picking Up In Store

The website and app let you search by your vehicle’s year, make, model, and engine. You can check stock at local stores, buy online, and pick up in store, often within an hour. Some areas also offer delivery.

Ordering online first has several benefits:

• You can confirm the part fits your vehicle.
• You can compare prices across brands.
• You can check stock before you drive to the store.
• You skip the wait at the counter.

Oreillys for Professional Mechanics

The company earns a large share of its business from professional shops. Its First Call program serves repair shops, dealers, and fleets with fast delivery, trade pricing, training, and support.

For pros, speed matters. A car on a lift that is waiting for a part costs the shop money. The company’s network of hub stores and distribution centers is built to get parts to shops quickly, often several times a day.

This pro business is a big reason the company has outperformed many retailers. When car owners pay a shop instead of fixing cars themselves, the shop still buys parts from a supplier like O’Reilly.

Store Hours

Most stores open early and close in the evening, seven days a week. Many open around 7:30 or 8 a.m. and close around 9 p.m., with shorter hours on Sundays. Some locations stay open later. Holiday hours vary, and many stores close on Thanksgiving, Christmas Day, and Easter. Use the store locator on the website or app to check your local hours.

How It Compares to Other Parts Stores

All three offer similar core services. The best choice often comes down to which store is closest, which has your part in stock, and which has the best deal that day.

Tips to Save Money on Car Parts

Whether you visit Oreillys or another store, these tips help keep repair costs down:

1. Get the code read for free before you buy any parts. Do not guess.
2. Compare house brands with name brands. Read warranty terms on both.
3. Buy online and pick up to catch web-only deals.
4. Join the rewards program and use it on every purchase.
5. Return your cores so you get your deposit back.
6. Borrow tools instead of buying them for one-time jobs.
7. Watch for seasonal sales on batteries, wipers, and coolant.
8. Keep receipts for warranty claims.
9. Do simple jobs yourself. Wipers, air filters, and bulbs are easy wins.
10. Ask questions. Counter staff often know local mechanics and common fixes.

Advice for First-Time DIYers

If you are new to working on your own car, start small. Swap your wiper blades, replace your engine air filter, or change a burned-out bulb. These jobs take a few minutes and need few tools.

Bring your vehicle’s year, make, model, and engine size to the counter. A photo of the old part, or the part itself, helps staff find the right match. Watch a video of the repair before you start, and never work under a car held up only by a jack. Use jack stands every time.

Working at O’Reilly

With nearly 97,000 team members, the company is a major employer. Common roles include retail parts specialists, delivery drivers, store managers, and distribution center workers. Many managers start at the counter and move up. The company has long promoted from within, and its current CEO, Brad Beckham, began his career in its stores.
