Grand Theft Auto IV
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. The abandoned factory on Industrial, Bohan has the Xero logo painted on storage tanks and on parts of the building, indicating that it was their former refinery before abandoning it and moving to 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.
Grand Theft Auto V
The company owns several inaccessible filling stations across San Andreas. ATM's and Jerry Cans are usually found at these gas stations. There is also an industrial building on Greenwich Parkway in the Los Santos International Airport, as well as a refinery in Blaine County. In the enhanced edition of GTA V, Xero has its own blimp.
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. It might also be based on Chevron, given the fact that much like Chevron, it has refineries on the East Coast, yet no presence in gas retailing there.
- The name of the brand is a parody of the term "zero gas", a mockery of the oil crisis.
- Based on the strong similarities between their logos Xero has with Xoomer from GTA: San Andreas, it is possible that Xero is a re-branded Xoomer, as the two chains share very strong similarities.
- It is possible to destroy the Paleto Bay branch during The Paleto Score, although when the heist is finished, its appearance will revert back to normal.
