In GTA IV, its gas stations are located in several places around Liberty City. The player cannot refuel or purchase Pharte gas from these stations, although they can blow up the gas pumps, cylinders and gas tanks around the RON oil facility in Leftwood and the Globe Oil complex near Port Tudor, both located in Alderney. The company's logo can be seen on Burritos around the city.
The company is also present in GTA V, once again having its livery on Burritos. On the vans, it says "Pharte Gas. Taken from humans by humans".
The company name is an obvious pun on "fart gas", a fact backed up by their slogan: "It's perfectly natural".
