Cold weather unit does not prevent the goo. That is water from condensation in the oil which is a normal thing that happens in a engine. Only long trips get rid of that. The insulation just keeps the water from freezing a little longer then the naked one. Run it long and hard. These engines are made to be revved and enjoyed. There is a red line for a reason. You can run them right up to that and they like it and will actually last longer. Lugging causes more wear that revving.
