A father and son who would not move.

O’Reilly Auto Parts grew out of a family’s long work in the parts trade. According to the International Directory of Company Histories (St. James Press, 1999), Michael O’Reilly left Ireland during the famine and settled in St. Louis in 1849, where he earned a law degree and worked as a title examiner. His son Charles Francis O’Reilly started in 1914 as a travelling salesman for Fred Campbell Auto Supply in St. Louis, and in 1927 was transferred, at his own request, to the Springfield, Missouri area.

By 1932, the Directory says, Charles F. O’Reilly was a manager of Link Motor Supply in Springfield, and his son Charles H. “Chub” O’Reilly was already working there. In 1957 Link was bought by Meyers Motor Supply of Joplin, Missouri, and the reorganisation that followed would have retired the father and sent the son to Kansas City. In an interview quoted by the Directory, Chub O’Reilly said he did not want to live in Kansas City because it was “too big,” and did not want to uproot his family.

So the two broke away. The Directory says they founded O’Reilly Automotive in November 1957, with Charles F. O’Reilly as president and his son as vice-president, in a rented and remodelled building in Springfield, and that some employees owned stock in the new firm. The company’s own history gives the opening date as 2 December 1957. Its website says O’Reilly Auto Parts began in Springfield in 1957 as a single store.

The Directory says Link tried to stop manufacturers from selling to the new company, but that the O’Reillys’ long dealings with the manufacturers’ sales representatives won them the brand-name parts they needed. At first the company sold mostly wholesale, to garages and industrial customers that employed professional mechanics, and gradually sold more to people fixing their own cars.

Ozarks roots, a jingle and a national footprint.

The business grew slowly and stayed close to home for years. In October 1960, the Directory says, O’Reilly set up Ozark Automotive Distributors to buy parts directly from manufacturers and supply both its own store and independent parts sellers around Springfield; a branch store in Springfield did not open until July 1965. In 1975 the company built a warehouse in Springfield to serve its stores, all of them then in southwest Missouri.

The company went public on 23 April 1993, Wikipedia says, with its shares traded on Nasdaq under the symbol ORLY. Growth then came through acquisitions of regional chains. Wikipedia says O’Reilly merged with Hi/LO Auto Supply of Texas and Louisiana in January 1998, bought KarPro Auto Parts of Arkansas in 2000 and Mid-State Automotive Distributors in 2001. In July 2008 it acquired CSK Auto Corp. of Phoenix; a year later the Springfield Business Journal reported that many of the CSK stores had yet to be rebranded under the O’Reilly name, and that the purchase had left the company short of office space in Springfield.

One part of the identity is sung rather than drawn. Wikipedia, citing the company’s own history of the jingle, says the O’Reilly jingle was created in 1999 by John Dillon, a founding member of the Springfield rock band The Ozark Mountain Daredevils, and that the current version dates from 2003. As Wikipedia quotes it, the jingle repeats “O’ O’ O’” before the full name, “O’Reilly Auto Parts.”

The name has also gone onto racing. Wikipedia says O’Reilly sponsored the NASCAR Cup Series’ O’Reilly Auto Parts 500 from 2017 to 2020, and that from 2026 NASCAR’s second-tier national series has carried the O’Reilly Auto Parts name, replacing Xfinity, as The Athletic reported in August 2025.

Design and documentation.

Car-service and tire brands are read from the road before they are read anywhere else. A fascia over a row of service bays, a pole sign at the curb and the lettering above each bay door are meant to be seen from a moving car or from across a parking lot, which is one reason such names are often short, their colours few and their letterforms heavy. Inside, the same marks can repeat on a smaller scale: on the tire wall, where stacked sidewalls sit under a branded header, on the counter, on the waiting-room wall and on the printed or emailed receipt.

Uniforms carry an identity into the bay itself. A name patch, a coloured shirt or a branded cap marks out the technician, and the same colours can run on to vans, tool chests and the paperwork that leaves the shop with the car. Where a name is franchised, a central owner can set the fascia, the sign and the colours while local operators run the bays.

Each guide below follows one name from its founding through its owners to the signs and stores that carry it today, and notes where an account rests on the company’s own word.

Still in Springfield.

The legal name is O’Reilly Automotive, Inc., which does business as O’Reilly Auto Parts. It is a public company listed on Nasdaq, and it has kept its head office in the town where it began. On 2 July 2009 the Springfield Business Journal reported that O’Reilly had begun site work for a new headquarters building in Springfield, just south of its existing corporate office on Patterson Avenue, with construction expected to finish in March 2010; the newspaper linked the project to the growth in corporate staff that followed the CSK purchase. Wikipedia says the company has been headquartered in that building since 2010.

The company has since moved beyond the United States. Wikipedia says O’Reilly announced in August 2019 that it would acquire Mayasa Auto Parts of Mexico; opened a distribution center and its stores in Puerto Rico in May 2023, according to a company release; and in December 2023 announced the acquisition of Groupe Del Vasto, which trades as Vast-Auto and is based in Montreal, taking the company into Canada. The company’s website now describes its stores as spread across the United States, Puerto Rico, Mexico and Canada. Wikipedia names Brad Beckham as chief executive.

The company also describes a set of values it calls the “O’Reilly Culture.” On its website it sums this up as “Our COMMITMENT To Our Customers and Our Team Members,” and it says that philosophy has been the foundation of the way it works since the beginning.

For a design guide, O’Reilly Auto Parts shows how a family surname, repeated in a jingle, can become a central part of a retail identity. Compare AutoZone, another American auto-parts retailer, and Valvoline, the motor-oil name. For this guide we use an Ozark green, a pine and a counter cream with a condensed sans, an unofficial interpretation; no product or logo is reproduced.
