its a minor leak therefore I haven't invested in a repair yet. The car has only 87000 miles at this particular time.

Always having to add oil even about a month after oil change. I know Northstar engines burn oil, but then I noticed underneath of car was wet with oil. (never dripped on driveway until recently). The mechanic changed a bolt or nut that goes under there, but it continued. Mechanic says that I probably have an oil pan gasket leak and that is major work to fix. Tells me to get a new car, but I can't afford one right now.
