Just do the SeaFoam treatment a hundred miles or so before your next oil change, then drain the old oil and add the full synthetic. Don't mix full syn with dino juice...might as well buy a blend if you're going to do that. The synthetic will help clean the engine, but you shouldn't need to change it before your regularly scheduled routine as long as you use a quality oil filter. Gaskets and seals that have become saturated with dino oil MAY pose a leakage problem with full syn oil, but IMO the benefits outway the risk.
