White smoke - how white? If it has a grey.blue hue to it, it's oil. If not, it might be coolant (head/gasket) or transmission fluid. The latter happens to me when I let off completely at (quite) high speeds - the manifold vacuum is so great, and my module leaks a bit, and causes tranny fluid to get sucked into the engine and be burned. The larger the leak in the module, the more smoke when you let off at high speeds, or the less vac is required. If your engine is overheating, it will be too lean - huge power loss. If you're getting smoke from oil, it could be rings or valve stem seals. Burning oil can foul plugs, causing power loss - but usually, at highway speeds, plugs become cleaner from oil burning, not dirtier.
