The biggest problem that arises with a slippery floor is the difficulty in precision maneuvering. Large fans or leaf blowers will allow for even less precision than the wheels, so it doesn't really solve anything (it would look cool, though). The only way to increase your stopping distance, turning radius, etc. is to increase your normal force without increasing your mass, as the post above describes. Other than that, your pretty much stuck with the oil slick.
