Mas Fuego Energy Drink is an energy drink featured in Grand Theft Auto IV.
Unlike Orang-O-Tang and Sprunk, this drink is not available for the player to drink. According to its radio commercial, Mas Fuego is for "men without balls". It sponsors the San Juan Sounds radio station and there is a billboard in Alderney City.. The name means "more fire" in Spanish. It might be a parody of the Burn Energy Drink.
