This is the dumbest (sorry) question I have EVER heard! Oil never goes bad. Its been sitting undergound for over 2000 years for goodness sake! It would only go bad after a LONG LONG time! By that I mean sitting in the engine for 30 years.

Sorry the question seemed so dumb! But I have heard that if a car sits for a long period of time,you should put fresh oil in.So,in theory,if you discover a car sitting in a barn for twenty years and want to restore it,you don't need to change the oil.Obviously I don't use my car that much.At the rate I'm going it would be about four years before a scheduled oil change.

Thanks for all the great advice guys! Up until a year or so ago the car was a daily driver,and I changed the oil and filter every two thousand miles( I know it was overkill,but I couldn't help myself;oops.I always did it myself,and enjoyed doing it.Also I always start the car every few days and let it run awhile and drive around the island a little bit.
I use Valvoline 10/40 Maxlife,which is a synthetic blend.Never any problems,and at 200,000 miles I never have to add any oil.I took an early retirement,and living on a two by four mile island there isn't too many places to go. But, tomorrow I'm going to go out and change the oil.
