I have a 2002 buick lesabre with 204k miles. It seems to be running fine but lately my gas mileage has fallen to 13 mpg. Since I have had it about a year it has been as high as 22 mpg. What could be causing this severe drop in mpg ? Thanks. Jeff

Did you go from mainly highway driving to city driving? A 50%+ decrease in MPG is pretty substantial.

No, sometimes more idling but not much
