...CAUSING THIS? I have a 1993 Cadillac deville that has 122,894 miles on it. Runs fine and engine sounds good but I only get 12 miles to a gallon on average.I read online and it seems most people with my car get around 16mpg in the city and 25mpg highway-i get 12 in city and on highway...any idea what could be causing this?
