my low fuel light usually comes on when my iformation center rads 50-60 miles left on the tank of gas. i drove another 40 miles one time from nyc to north brunswick,nj. i dont know how these cars get such good gas mileage but it seems the faster i go on the highway the more gas mileage i get. i drove from ga. to ny and had to fill up once, i had gone like 470 miles b4 i stopped for gas and i still had just under a quarter tank left
