Not that I've heard. Synthetics have various clear benefits (extreme heat, cold, long oil cycles, engines that shear oil more than others, etc.), but I'm personally unaware of the "Remains on surfaces longer" argument. Perhaps others have heard differently (something other than just the usual rumors).
