“Needed to replace an old Watchdog Sump Pump battery. Got a Duracell and kept the old yellow cap with the hole for the water sensor. Employee was AMAZING and provided advice and guidance on what to do and how to be safe. I will be coming back here. Great service!!”
“Robert the manager went above and beyond! I’m a local store manager and my battery was cooked and couldn’t start it and with work being hard to get in somewhere. He not only helped me with my purchase he came to my work and installed it for me in the parking lot!!! Not only that snowing like crazy and windy and he knocked it out in 20 min. Companies and employees like this that make you a lifetime customer! Will never purchase a battery anywhere else! Thank you again from one manager to another!”

“These guys are great. I've been buying my batteries here for years and they always take care of me and are super knowledgeable on what you need. No games, just straight excellent customer service with a great product.”
“So today I found myself driving my 2008 Hyundai Tucson with NO low beam headlights. This should have been an easy fix but I ended up visiting 2 autozones, 1 advance auto parts, and another O'Reilly in my neighborhood. Not one of them was willing to help with the replacement. Then I found Eduardo at the Algonquin O'Reilly's auto parts. In spite of the drizzling, damp weather, Eduardo was able to replace both of the headlamps. He truly is a hero and I am truly grateful. Give Algonquin O'Reilly's your business, they truly earned it.”

“They always seem to have hard to get parts, even if they have to get it from another location..it's usually about a day. in most cases, be there by 4 the same day..”
“Awesome place. My wife had to get the battery replaced in her car and Edwin, the Store Supervisor took care of everything for her, including installing it and cleaning the corrosion off the posts. All this while being the only employee on site at the time and having to take care of other customers at the same time. He didn't make excuses or tell anyone he couldn't help them. He stepped up bigtime and took care of everyone!! Great employee!!”
“I don’t usually leave reviews, but Mark at the Cary, IL O’Reilly Auto Parts absolutely deserves one. From the moment I walked in for a new battery, Mark went above and beyond—knowledgeable, patient, and genuinely invested in helping me get exactly what I needed. He didn’t just point me to a shelf; he asked the right questions, double-checked compatibility, and made sure I left confident in my purchase.
What really stood out was his professionalism and attitude. You can tell Mark truly cares about customers and takes pride in his work. That kind of service is rare these days, and it completely changed my expectations of an auto parts store. Because of Mark, this O’Reilly’s will be my go-to from now on. If you’re in Cary, do yourself a favor and ask for him—you won’t be disappointed.”
“I had an amazing experience at O’Reilly Auto Parts! From the moment I walked in, the staff was friendly, knowledgeable, and genuinely willing to help. They took the time to answer all my questions, made sure I got the right parts for my vehicle, and even offered helpful advice without making me feel rushed or overwhelmed.
What really stood out was their professionalism and attention to detail. It’s not every day you find a team that actually cares about customer service the way they do. The store was clean, organized, and well-stocked, which made the whole process quick and stress-free.
If you’re looking for reliable service, knowledgeable staff, and a smooth experience, this is definitely the place to go. I’ll absolutely be coming back and recommending this location to others!”
“Went in right before close to grab a headlight. Mack volunteered to install it for us without even being asked. He has us in and out in less than 10 minutes. Great service!!!”
“Very helpful, pleasant, and knowledgeable staff! They don’t have it in stock? You can order it this morning and pick up in the afternoon. O’Reilly Auto Parts is the official automotive parts supplier to Solar Van Man!!”
