Grand Theft Auto V
Xero is a petroleum company featured in Grand Theft Auto IV and Grand Theft Auto V. It is a BAWSAQ-listed company. It could be based on Exxon, as both have an "x" in their names and share the same colors in their logos. Its name and logo design also appear to be similar to that of Xoomer in Grand Theft Auto: San Andreas. 'XERO' is a pun of ZERO GAS, a mockery of the oil crisis.
Unlike its competitors, such as RON, Globe Oil, and Terroil, Xero does not appear to have set up any gas stations in Liberty City, although it does operate a refinery at the southwestern corner of the Acter Industrial Park in Alderney. Xero storage tanks and faded advertising of the brand can also be found in selected parts of Liberty City, and Xero sponsorship vinyls are visible on certain Bati Customs designs.
Many Xero filling stations and their adjacent convenience stores can be found in San Andreas. The company also owns an industrial building at the Los Santos International Airport, as well as a refinery in Blaine County.
