what would make a vehicle smell like gas
Use up a full tank of the premium gas. By this time, the smell of the high-octane gas should have worked its way around your car, giving it a smell of racing fuel. Pour about 16 ounces of premium fuel into a jerry can or gas can. Pour a small amount of fuel from the jerry can onto a high-density cloth. Dab the cloth lightly on the underside of the two front seats of the car. Then use a damp cloth to dab the same areas to remove any excess fuel. This will slightly amplify the racing gas smell of your vehicle, if you require such action.
