A lot of speculation here... I ran used and new for thousands of miles and generally used runs and starts better but can.be overruled easily with a bit of petrol in either. As for the dewatering this isnt necessarily a requirement as long as you leave the oil to stand for a long time as most of the water seperates (not all of it in any case however the tiny percentage will not do enough damage over the thousands of miles vs the time/effort/cost involved in heating and dewatering) bearing in mind what a bosch pump actually costs.
As long as your smart about it and not dragging the oil off the top of a canal or something and putting it straigh into your tank.
