You’re standing in your driveway, hood up, grease on your knuckles, and that one specific 10mm socket has seemingly vanished into another dimension. Or maybe the alternator finally gave up the ghost right as you were planning a grocery run. It’s Sunday morning. Most of the world feels like it’s hit the pause button, but your car doesn't care about the calendar. You need parts. You're probably asking, is O’Reilly Auto Parts open on Sunday, or are you stuck waiting until Monday morning to get back on the road?
The short answer? Yes.
Usually.
Honestly, O’Reilly is one of the more reliable options for weekend mechanics. Unlike your local boutique coffee shop or that family-owned hardware store downtown, big-box auto retailers know that Sunday is "Project Day" for millions of Americans. It’s the only time most of us have to actually crawl under a chassis. However, there are some weird quirks about Sunday hours that can catch you off guard if you just assume they’re open late like they are on a Tuesday.
The Reality of O’Reilly Auto Parts Sunday Hours
Most O'Reilly locations across the United States do keep their doors open on Sundays. They understand the market. If they weren't open, you'd just go to AutoZone or Advanced Auto Parts, and they know it.
Typically, you’ll find that O’Reilly opens a bit later and closes a bit earlier on the Lord’s Day. While a standard weekday might see them open from 7:30 AM to 9:00 or 10:00 PM, Sunday hours are often compressed. Think more along the lines of 9:00 AM to 7:00 PM or 8:00 PM. It varies. It really does. I’ve seen stores in rural Texas close at 6:00 PM on a Sunday because, frankly, everyone is at home or at church, while stores in Los Angeles or Chicago might stay humming until 9:00 PM.

Why Geographic Location Matters More Than You Think
Ever heard of Blue Laws? They’re these old-school regulations that restrict certain business activities on Sundays. While they’ve mostly faded into history, some counties—especially in places like Bergen County, New Jersey, or certain parts of the South—still have them on the books. In those specific spots, even a massive chain like O'Reilly might be forced to keep the lights off. It’s rare for auto parts, which are often considered "essential" for transportation safety, but it's not impossible.
Then there’s the staffing reality of 2026. Labor markets fluctuate. If a specific branch is short-handed, the manager might decide to trim Sunday hours first to give their core team a break. It sucks when you’re the one needing a starter motor, but it’s the world we live in.
Is O’Reilly Open on Holiday Sundays?
This is where things get slightly more complicated. If Sunday happens to fall on a major holiday, the rules change.
Take Easter Sunday, for example. Many retail chains choose to close entirely to give employees time with family. O'Reilly has historically stayed open on many holidays where other retailers fold, but Easter is often the exception or a day with very limited "emergency" hours.

If it's just a "regular" Sunday, you're fine. If it's a Sunday that doubles as Christmas Eve or New Year's Eve, expect those doors to lock much earlier than the sign says. Usually, they'll post a physical flyer on the door a week in advance. If you're planning a big Sunday job around a holiday, check that door on Saturday. Trust me.
What Services Can You Actually Get on a Sunday?
It's one thing for the store to be open; it's another for them to have the "expert" on duty. O’Reilly is famous for their "Professional Parts People" branding. On a Sunday, you might get the veteran who has rebuilt ten small-block Chevys, or you might get the college kid who just knows how to work the computer.
However, the core "convenience" services almost always run on Sundays:
- Battery Testing and Charging: If your car won't start, you can lug that heavy lead-acid beast into the store. They’ll hook it up to the diagnostic machine for free. If it just needs a charge, they’ll usually do it, though it takes an hour or two.
- Check Engine Light Scanning: This is the big one. If your dash is glowing like a Christmas tree, they’ll bring the OBD-II scanner out to the parking lot. You get the code, you get the printout of what it probably is, and you can buy the sensor right then and there.
- Wiper Blade Installation: If it’s raining on a Sunday, they’ll usually help you snap those new blades on if you aren't sure how the clips work.
- Fluid Recycling: Most locations will take your used motor oil and oil filters on Sundays, provided their collection tank isn't already full from a busy Saturday.
Ordering Parts on a Sunday: The Hub Factor
Here is a detail most people miss. O’Reilly operates on a "Hub" system. If your local neighborhood store doesn't have a specific water pump in stock, they check the nearby Hub store. On a Tuesday, a delivery driver might bring that part to your local store in two hours.
On a Sunday? Delivery schedules are often skeleton-crews or non-existent. If your local store doesn't have it, you might have to drive 20 miles to the Hub yourself to pick it up, or wait until Monday morning for the shuttle truck. Keep that in mind before you tear your engine apart.

How O’Reilly Sunday Availability Compares to Competitors
Honestly, the "Big Three"—O’Reilly, AutoZone, and Advance—tend to move in lockstep. If one is open, they’re all open. O’Reilly tends to have a slightly more "pro" focus, often catering to independent shops. Since most independent shops are closed on Sunday, the O'Reilly staff on weekends is purely focused on the DIYer.
In my experience, O'Reilly's inventory system is a bit more robust than some of the others, but their Sunday staffing can be hit or miss depending on the region. If you’re looking for something super niche—like a specific gasket for a 1974 Datsun—Sunday is a tough day regardless of which store you choose. You're mostly looking for the basics: oil, filters, batteries, brakes, and bulbs.
Pro Tips for Your Sunday O’Reilly Run
- Use the App for "Buy Online, Pick Up In-Store" (BOPIS): Don't just drive there. Check the inventory on the app first. If it says "In Stock," buy it right then. This "claims" the part so some guy five minutes ahead of you doesn't grab the last one off the shelf while you're sitting in traffic.
- Call Ahead for Battery Checks: If it's a blistering hot or freezing cold Sunday, everyone's battery is dying. The testing machine might be backed up. A quick 30-second phone call can save you a wasted trip.
- Check the "Last Pickup" Time: If you need a part transferred from another store, ask them what time the last "shuttle" runs. On Sundays, it's often early—like noon or 1:00 PM. After that, you're waiting until Monday.
- Bring the Old Part: Sunday is not the day for "I think it looks like this." Take the old, greasy part with you. Match it up at the counter. Nothing ruins a Sunday afternoon like getting home and realizing you have the "left" side brake caliper when you needed the "right" one.
The Verdict
Yes, is O’Reilly Auto Parts open on Sunday is a question with a positive answer 95% of the time. They are the backbone of the weekend warrior's garage. Just remember that "open" doesn't mean "open late."
If you're planning a repair, aim to get to the store before 2:00 PM. This gives you a buffer in case you get the wrong part and need to swap it before they close their doors at 7:00 or 8:00 PM.
Actionable Next Steps:
- Download the O’Reilly App: It’s the fastest way to verify Sunday hours for your specific ZIP code without sitting on hold.
- Verify Inventory: Use the "My Store" feature to ensure the part is actually on the shelf before you leave the house.
- Check the Weather: If severe weather hits on a Sunday, local managers have the discretion to close early for safety. If it’s snowing sideways, call first.
- Locate Your Nearest Hub: Find out which O'Reilly in your area is the "Hub" location. They have ten times the inventory and are the most likely to stay open the longest on a Sunday evening.
Your Sunday doesn't have to be a wash just because a belt snapped. Most O’Reilly locations are ready and waiting to help you get that project finished before the Monday morning commute kicks in. Just don't wait until 10 minutes before closing—nobody likes that guy.
