Demonoil is an engine lubricant brand that appears in Grand Theft Auto Online as part of the Arena War update, and Grand Theft Auto: Vice City - The Definitive Edition.
Description[]
Grand Theft Auto Online[]
Demonoil is featured in the Maze Bank Arena during the Arena War gamemode, appearing on animated ad screens and as a minor sponsor on various Arena War vehicle liveries. The brand is also occasionally advertised on the television in the Arena Workshop along the Career Wall.
Grand Theft Auto: Vice City – The Definitive Edition[]


Demonoil later makes a brief appearance in Grand Theft Auto: Vice City - The Definitive Edition on a model calendar in the Print Works featuring its branding, replacing the Pervelli Calendar brand from the original. As with other HD Universe brand appearances in The Definitive Edition trilogy, this appearance is considered non-canon to the 3D Universe.
Influence[]
Demonoil may draw inspiration from Motul and Havoline, with branding that shares notable similarities, while also faintly resembling the Japanese motor oil company Moty's.
