In 1927, the company's gasoline was being tested on U.S. Highway 66 in Oklahoma, and when it turned out that the car was going 66 mph, which was fast at the time, cementing the idea of "66", the company decided to name the new fuel Phillips 66. YES, I do remember in 1953... Gallon of gas was 10 cents!
