My 2013 Boss now has 4300 Km, I did my first oil change at 1600 Km ( 1000 miles ) Mobile 1 5w 50. The car is burning 1 litre per 1600 Km. I was hoping this would change as she broke in, I have seen no change in the consumption rate so far. I do mostly weekend trips with the Red Key,lets say spirited driving, I know others have issues with this as well,does this get better with more milage or is there something wrong with my engine? Car runs great no other complaints.
