i just bought a 92 deville and it only has 75k on it. on the average mpg is says im getting 15.5 when in reality im only getting 9-10. Is this because i use AC and it takes away from the gas? I dont ever hit the petal past quarter. Also the motor mount needs to be replaced but other than that it should be in perfect condition?
92 Cadillac deville is only getting 10mpg?
