2002 Cadillac Deville • 120,000 miles

Ran car out of gas. It smells of fuel when running with the door open and after I turn it off. The gas mileage is terrible! Goes from 5mpg up to 10mpg. Sometimes when I fill it up will go up to 15 mpg. But rarely. It has never gotten good gas mileage, but since I ran out of gas it is terrible.

If you smell gas, there has to be a leak. Check the injectors under the hood to make sure there are no leaks. Also, check the fuel line from the tank to the engine for leaks.
