<shitty/high> gas mileage


- And I want a new car! And I want the City to pay for it all! (........) Something with reclining leather seats, that goes really fast and gets really shitty gas mileage!
RoboCop, movie

The relatively low cost and high gas mileage are the making of Chevrolet's Geo Metro cars.
(American Idioms)

Are both 'shitty' and 'high' supposed to be 'good' gas mileage? (a large number of miles using a particular amount of fuel)

    As JulianStuart says, 'shitty gas mileage' is poor gas mileage, lots of fuel used per mile. Large, powerful motors use lots of fuel per mile. 'Shitty gas mileage' in the case of RoboCop is an indirect way of saying that he wants a large powerful motor that will make the car go really fast and accelerate rapidly. He wants a muscle car.
