The SUV car on gas needs to be sparingly used and the driving habit needs to be radically changed. You should not have the tendency to use sharp break nor should you ever stress on rash driving to avert the blinking orange signal (next one will be red). In case you have multi car option, simply use the car occasionally; in case of single car, use tactics. Check your car finance tenure and the outstanding on this car. Meanwhile ask the nearest car dealer for the price of this car. If you find that the outstanding on the car is more than its market price, you have to adjust your pocket and habit for the gas consumption, otherwise, sell it off and next time go for a fuel efficient car.
