This mod adds to GTA 4 gas stations, a fuel tank (gasoline runs out, you can refuel), the ability to turn on an alarm, the ability to turn on the speedometer and car damage indicators.
If you stall, you can call a tow truck or a mobile gasoline tanker. Prices vary from gas station to gas station. In general, realism in GTA 4 goes to a new level. Installation in the archive.
