My car seems to be running out of gas quicker than usual. What could be the cause of this?

It might be just a coincidence. Or you might be getting poor mileage, or something else could be causing it. I’d suggest you keep a record of how much gas you put in each time, and how far you drive.

Oh, so you’re in a car right now and you’re running out of gas?  I’m afraid I don’t have any specific expertise about cars.  Perhaps I could do some research for you?
