Caltex began in 1936 as the California Texas Oil Company, a joint venture between the Texas Company (later named Texaco) and Standard Oil of California (later named Chevron Corp.) to market oil from newly gained concessions in Saudi Arabia. It was renamed Caltex Petroleum Corp. in 1968. (As an interesting side note: in the Vincent Price movie 'The Last Man on Earth' released in 1964--he gets his gas from a Caltex tanker.----). The two parent companies merged in 2001 to form ChevronTexaco (renamed Chevron in 2005) and Caltex remains one of its major international brand names.
Caltex Petroleum Australia Pty. Ltd. (ASX: CTX) until March 2015, Caltex was owned 50 percent by Chevron, and 50 percent by Australian shareholders. In March 2015, Chevron sold down its 50% holding to Australian shareholders.
On 27 May 2009 Caltex announced a proposal to acquire 302 Mobil and Mobil Quix service stations in Sydney, Melbourne, Brisbane and Adelaide, subject to approval of the Australian Competition and Consumer Commission. The ACCC subsequently opposed the takeover on the grounds that the acquisition could result in diminished competition. Caltex subsequently abandoned the acquisition, with Mobil entering into an agreement to sell the same sites to 7-Eleven Australia.
Caltex operates the largest oil company retail network in Australia, however the supermarkets Woolworths and Coles have a larger market share than any of the oil companies operating in Australia.
As of August 2012, Caltex operates two petroleum refineries in Australia: one at Kurnell in Sydney, New South Wales, and one at Lytton in Brisbane, Queensland. The Kurnell Refinery will cease operations in 2014, and part of the existing infrastructure such as wharfs and tanks will be converted to a fuel importation terminal.

Caltex branded sites can have any of the following types of convenience stores.
Star Mart: A large store containing a bakery, coffee and hot food as well as convenience items and an ATM. Toilets are usually located inside. Usually open 24 hours. The New Zealand operations were sold off and rebranded as Fix stores.
Star Shop: A smaller store with just convenience items and packaged foods and limited operating hours.
Woolworths: Sites that accept a varying but basic four cents per litre discount offer from Woolworths. Shops are branded as Woolworths. Most are the same as a Star Mart, but some are the size of a Star Shop.
Woolworths joint venture
In 2003 Caltex Australia entered into a joint venture agreement with large supermarket retailer Woolworths Limited. Shortly after in 2004, a similar fuel discount offer was launched by rival Coles Group. Woolworths' existing "Plus Petrol" service stations received Caltex branding and, similarly, Caltex service stations received Woolworths branding—the joint venture outlets became Caltex Woolworths. However this was the case only with certain Caltex service stations close to Woolworths supermarkets and many remain unassociated with the fuel discount offer.
From 1987 until 1993, Caltex was the title sponsor of Colin Bond Racing. From 2000 until 2007, it was title sponsor of Stone Brothers Racing with Russell Ingall winning the 2005 championship. In 2016, Caltex will again become title sponsor pf the Triple Eight Race Engineering car of Craig Lowndes, having previously been an associate sponsor of the team.
Caltex South China Investments Limited operate over 20 stations in Guangdong through various local joint ventures. GS Caltex, from South Korea, have moved into China and operate a few oil stations in Shandong Province.
Texaco began kerosene sales in Hong Kong (and neighbouring China) in 1913 and Caltex began operating in Hong Kong in 1937 with a diesel terminal. The terminal was situated in Tsuen Wan in the New Territories. The road leading to the terminal was therefore named as Texaco Road. The oil terminal was later moved to Tsing Yi where it is and the land plot in Tsuen Wan was developed into apartments named Riviera Gardens. Caltex operates over a dozen service stations through Hong Kong Island, New Territories and Kowloon.
In South Korea, Chevron has operated under the brand name GS Caltex since 1967.
Caltex was established in the Philippines in 1917 when Texas Company began marketing its products in the Philippines through a local distributor, Wise and Co. In 1921, Texaco (Philippines) was formally established and opened its office in Binondo, Manila. Eleven years later, its Pandacan oil depot was converted into a key distribution terminal to bring products by barge to nearby provinces. Caltex celebrated its 75th anniversary in July 2011. They only sell two kinds of gasoline namely Caltex Gold (95 octane) and Caltex Silver (91 octane) and one kind of diesel named Caltex Diesel. All these products contain Techron. 
A quarter of Caltex's service stations are located in South Africa making it one of the country's top five petroleum brands. As a subsidiary of Chevron it also owns a refinery in Milnerton, Cape Town which has a production capacity of 100,000 barrels per day and produces a range of petrochemical products which include petrol, diesel, jet fuel, liquefied petroleum gas, fuel oil and paving asphalt. The company also has a lubricants manufacturing plant and laboratory in Durban.
Some Asian operations are run by Caltex (Asia) Limited, based in Taipei. Caltex has a joint venture aviation refueling business in Taiwan airports with Formosa Plastics. It also sells small quantity of lubricants into Taiwan market.
