I'd keep driving...
Danger Will Robinson - - sorry - I'm old - while the oil may not go bad the stuff added to the oil decays over time - there are detergents and other "stuff" added to those dead dinos that help keep your engine alive - I'd change the oil and the filter - that's why they recommend both mileage (like "every 3000 miles) and time (like "every six months") -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.This is the dumbest (sorry) question I have EVER heard!

The problem would be water contamination and gasoline contamination. BUT if the car was stored, I don't think it would be a real issue. Oil sitting in the pan is just like in the bottle, the worst condensation would be the humidity in the crankcase but there is only so much water in there.In that case I'd consider the annual oil change a preventative measure, unless you use an oil analysis program. Reason, combustion products that make it past the rings and into the crankcase can become corrosives over time. Without at least once a month running of the engine, water can also develop in the oil due to condensation, especially in coastal areas like yours. This water will mix with the combustion products over time and cause the corrosive to develop. Alternately drive your Saab, mon and make this a moot point. :lol:
