oilio

Oilio is a motor oil and engine lubricant company. Its name and branding are associated with vehicle maintenance products, placing it among the automotive businesses connected to Grand Theft Auto's vehicle culture.

The company first appears in Grand Theft Auto Online with the Los Santos Tuners update. An Oilio banner hangs inside player-owned Auto Shops, where the brand is presented as workshop advertising rather than as a character or a location.

Oilio is also listed as an active business for Grand Theft Auto VI. The available material identifies it as a vehicle-parts business, but does not state where its products are sold, who operates the company, or what role it has in the game's story.
