Phillips 66

A major American energy company that refines crude oil into gasoline, diesel, and jet fuel, and runs a vast network of pipelines, terminals, and chemical plants. It traces its roots to the Phillips Petroleum Company, founded in 1917 in Oklahoma by brothers Frank and L.E. Phillips, and was spun off from ConocoPhillips in 2012. The "66" in its name dates to 1927, when a test car hit exactly 66 mph on Route 66 while road-testing a new gasoline.
