How many quarts of oil should be put in my car for an oil change?

in most cases it will not hurt the vehicle....however, too much oil in the pan could cause higher oil pressure which in turn can cause oil to be forced past the rings and into the cylinders......you'll then burn oil, gumming the ignition system......that in turn will effect performance and engine life.....i personally would have drained a bit off as well just to be safe
