Demonoil

Demonoil is a motor oil and engine lubricant company in Grand Theft Auto Online added as part of the GTA Online: Arena War content update.

Description
Demonoil is a motor oil company appearing inside the Maze Bank Arena, Arena War on animated billboard screens, as well as liveries. It can also be seen sometimes advertised on the TV on the Arena War Career path wall in the Arena Workshop.

Demonoil could likely be based on the real life Motul and Havoline motor oils, which share similar colour schemes. Demonoil's colour scheme and branding is also similar to the japanese motor oil company Moty's.

Trivia

 * The name Demonoil is likely a play on the word "Demonoid".
