What about the nano filtration. Do you now TRABOLD filters? I get infomration that if you used this filter you avoid the change of any kind of mineral oil.

No matter what type of filtration system you use you will have to change the oil at some point. A filter does nothing more than remove solid contaminates. The additive package of the oil will still get depleted, acids will form, water condenses in the oil, oil oxidizes.... and so on. A filter is only one part of a properly implemented maintenance program.
