Even though latest cars are equipped with an advanced EVAP system to prevent evaporation from happening, gas will still evaporate from the tank if your vehicle is parked in the sun. Parking in the shade will keep your vehicle cooler and reduce fuel from evaporation.<\/li>\n\n\n\n<li>You must try to fill fuel in your vehicle during the early morning or late night. It remains warmer during the afternoon and early evening. This would prevent gas from getting evaporated.<\/li>\n\n\n\n<li>To keep the EVAP system operating properly, you must re-install your vehicle\u2019s gas cap immediately after refueling. Addition to that, you must apply for a good rust protection to keep the system line corrosion to a minimum. Make sure you always check the engine lights.
