I am considering replacing most fluids with synthetic in my 195 960 sedan and wondered if anyone had any thoughts on this. I would use Amzoil engine oil, brake fluid, and transmission fluid. I am hopeful it will result in less wear, and better performance. I do know that in either event, I need to have the systems professionaly vacuumed when switching, and that filters should be changed frequently after the switch to synthetic because of the better cleansing properties of synthetic. All thoughts are welcome.
