If the oil does not contain water and is reasonably clean (looking) it will be fine sitting. If the car is used for short trips in a cold climate there will be free water from condensation, and water is not good in the oil tank or in the engine

On other cars and bikes I have always replaced oil at 3000 miles intervals, but with the stupid cost of good oil here and the 12 liter capacity it is always tempting to stretch it. Typically a good quality Pelican Forum approved oil is 400-450 dollars for 12 liter, and that is painful.
