The Pioneer Oil Refinery was the first successful oil refinery in California, built in 1876 off Pine Street in Newhall, Santa Clarita, California. The Pioneer Oil Refinery was designated a California Historic Landmark (No.172) on March 6, 1935. Pioneer Oil Refinery is the oldest existing refinery in the world. The Lang Southern Pacific Station railroad line served the refinery. In 2020, the refinery was added to the National Register of Historic Places; it is the only site on the National Register of Historic Places within the city of Santa Clarita.
Pioneer Oil Refinery was built by California Star Oil Works, which became part of Standard Oil of California and then part of Chevron. Chevron still owns the Pioneer Oil Refinery land. Chevron has plans on the table to restore the site. Some of the original parts of the refinery were taken away after it closed in 1884, some to museums and other parts to private collectors. The large kettles used to refine the crude oil in to kerosene and benzene are still on the site, along with an old wooden drill tower. Chevron still gives some tours of the site.
