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. 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 ceased operations in 2014, and part of the existing infrastructure such as wharfs and tanks will be converted to a fuel importation terminal.
Most sites stock all of these products, however Bio E10 Unleaded is the least common and Regular Unleaded the most common. Bio E-Flex is stocked in approximately 30 sites on the eastern seaboard.
Each site only sells one of these 3 products.
Autogas is available at selected sites.
Caltex sells Delo, Havoline, and Revtex brands of motor oil.
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.
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.

Caltex operates over a dozen service stations through Hong Kong Island, New Territories and Kowloon.
