Actually, because such short runs only serve to accelerate the contamination of the oil, entrain more air, and heat the oil up; this only serves to accelerate the oxidation chain I described above, worsening the formation of the organic acids.
We store several high end cars for select clients in a secure environmentally controlled storage facility. None of the car are started for the entire storage period. Over the 30 or so years we have offered this service, UOA's taken in the spring have shown no degradation of the oil, and bore scope cameras have shown no apparent rust formation of any rust or corrosion.
