Pennzoil's Slogans & Taglines

Pennzoil is an American oil company founded in Los Angeles, California, in 1913. Its origins trace back to 1889 as South Penn Oil Company, a production unit of John D. Rockefeller's Standard Oil Trust. The name Pennzoil emerged in 1916 when distributors began marketing motor oil from Pennsylvania refineries, and the iconic Liberty Bell logo—symbolising American independence—was adopted the same year. The brand's enduring slogans have evolved across eras: from the 1950s "Sound your Z, insist on Pennzoil" to "Quality in every extra mile" in the 1980s, and the modern promise "Long May We Drive," which reflects a purpose to prolong engine life and inspire every journey. Acquired by Royal Dutch Shell in 2002, Pennzoil remains a leader in synthetic motor oils, including the innovative Pennzoil Ultra Platinum made from natural gas. Headquartered in Houston, Texas, it continues to power everything from daily commuters to NASCAR racers, proving that over a century of lubrication expertise can keep engines running stronger and longer.
