Some people in the classic car world, and i've read people say it on this board too, say that conventional oils are better for classic cars that are used infrequently, since they "stick" to the parts of the engine more than synthetics which have a lower surface tension it seems and drain away from the engine parts quicker so at startup when most of the oil is in the sump there will be more residual oil left on the engine parts.
Is there any truth to this? Is there any particular group of oil that sticks to engine parts better than others?
