The vehicle oil slick is a weapon in GTA2 mounted in a car in a car shop which you throw in the ground and make other vehicles slip on ground without damaging it. Vehicles are unmanageable when they slip on the oil slick. Oil slicks can be used to get rid of a pursuer or block the passage to some weapon on a multiplayer game. The oil slick does not damage cars by themselves, but it is possible to to cause the victim to drown into the water or explode in a vehicle mine.
