We finally got an O'Reilly's close to me, they just opened one up about a mile or two from my house. I took a stroll through the store for the first time today and saw that they carry Wix which is cool, no other chain store carries them except NAPA where they are sold as their in-house brand. Also O'Reilly's turns brakes and flywheels which is cool since Pepboys stopped doing that a few years ago. Now that I have O'Reilly's as an option I'm wondering what their parts quality is like compared to AutoZone or Advance? Advance is the farthest away, though their stuff has been vastly improved since they acquired Carquest but I still wouldn't put them on quite the same level as NAPA. AutoZone has the best rewards program but their Duralast parts are hit and miss on quality. Seemed to me that the Duralast stuff used to be better. For the past few years I've been buying parts from RockAuto and oil from Walmart. I'm fine with continuing to do that, but I'm genuinely curious what people think of O'Reilly's.
