I do my own changes. I live in apartments where you cant change it yourself, so i go to my gf's and use her driveway. This 2.4L engine is in my friends pontiac grand am, he also lives in the same town houses as me. Well, he had no place to change it, so we bought the oil and had sears put it in for $10. Thing is, they put down that it was a v6 3.4, when in fact it was a 2.4 4 cyl. The dip stick reads about half way above the full line, or reads around another half a quart. Im pretty possitive this isnt nearly enough extra oil to cause any problem. I just wanted to make sure, this isnt my car, and this is my friends first synthetic change, as i talked him into doing it. the car has 43k miles on it, and was well maintained. Anyway, i am sure its fine. Thanks for your help.
