Hi ive had my 2011 MKZ for five weeks now. i bought it with 43,710. commuting to work ive put about 500 miles on the car. i'd like to know what maintenance i should do besides a fresh oil change. computer says my oil is at 75%. this is my first sedan, im coming from a 98 explorer. my car did not come with the owners manual. i'd like to know what the manufacture suggests and what everyone here has done. thank you in advance.
