1916–1969

During September 1919, Harry Sinclair restructured Sinclair Oil and Refining Corporation, Sinclair Gulf Corporation, and 26 other related entities into Sinclair Consolidated Oil Corporation. In 1932, this new entity was renamed Consolidated Oil Corporation. In 1943, it was renamed Sinclair Oil Corporation. Near the beginning of the

and reached the international press, Mussolini accelerated the negotiations, with a deal signed on May 4, 1924 (although without an official meeting, to avoid public outcry). Because of this, Sinclair Oil Company is known for having made "large payments to leading Fascists — all acting as intermediaries for Benito Mussolini — in return for an exclusive monopoly to drill for oil on Italian soil and in the Italian colonies". The deal was reported in a press release by the Head of Government (Mussolini) issued on the night of May 15, 1924, and published by most newspapers on the following day. The press release assured the public that Sinclair Oil had been awarded its contract on a competitive basis and had provided guarantees it had no relations with the international oil trust. This case of corruption was reported by the anti-fascist politician

): Matteotti accused Sinclair Oil of being a pawn of Standard Oil, as well as revealing "grave irregularities concerning the concession." Matteotti's theses were echoed in the notes of Epifanio Pennetta, who contributed to the preliminary investigation on the murder: "To all appearances," companies like Nafta and Saper "were in competition with the Sinclair company, while in fact they were in cahoots with Sinclair" and added that Sinclair Oil was actually working "in concert" with Standard Oil. During the Great Depression, Sinclair saved many other petroleum companies from

, and the Rio Grande Oil Company in California. The purchase of Prairie also gave Sinclair a 65% interest in Producers and Refiners Corporation (or Parco), which Sinclair subsequently acquired when Parco entered receivership in 1934. Lastly, in 1936, Sinclair purchased the East Coast marketing subsidiary of Richfield Oil Company, which had operated in receivership for several years. Richfield then reorganized, resulting in the creation of the Richfield Oil Corporation. Sinclair was instrumental in transferring capital and managerial assets into Richfield. Thirty years later, Richfield merged with Atlantic Refining, located on the East Coast, forming Atlantic Richfield. At the Chicago World's Fair of 1933–1934, Sinclair sponsored a dinosaur exhibit meant to play on the link between the formation of petroleum deposits and the time of dinosaurs, now a largely discredited misconception. The exhibit included a 2-ton animated model of a ''

As a result, the East Coast operations of Sinclair were sold to BP. After the ARCO acquisition, many Sinclair stations in the Midwest continued to use the dinosaur logo and opted out of using ARCO's "diamond spark" logo. Some northwest Sinclair stations partially retained the Sinclair brand for a time, using ARCO's blue rectangular logo, including the "spark" graphic, but with the word "Sinclair" substituted for ARCO.

The high-octane fuel blend was called "Dino Supreme" and regular gas was "Dino", trade names used since 1961 when many oil companies still used trade names for their fuels instead of generic terms such as "regular," "premium," or "unleaded". Before that time, Sinclair's trade names for its gasoline products included "Power X" for high-octane fuel and "Sinclair H-C" for regular gas. Sinclair also has marketed products such as Dino, Dino Supreme, and Opaline motor oils. In August 2021, HollyFrontier announced the acquisition of Sinclair Oil. A new company named ''HF Sinclair Corporation'' would be formed in 2022. Under the agreements, Sinclair Oil's branded marketing business and all related commercial activities and its refineries and related operations and assets in Casper and Sinclair, Wyoming, would be combined with HollyFrontier. Sinclair Oil's logistics and storage assets, including approximately 1,200 miles of pipelines, two crude oil terminals and eight light product terminals, would be combined with Holly Energy Partners (HEP). It was expected that the vast majority of Sinclair Oil employees would be invited to continue in their positions following the combination. The transaction did not include exploration and production assets owned by Sinclair Oil & Gas Co.
