quote:It depends on where the return oil galleries drain into the pan (or even how the car is tilted at that moment). If upstream opposite from the drain plug, there might be some rinsing action. You could catch this rinse oil in a clean container, and decide for yourself if it's worth it for your case. To me it seems as if there's actual crud on the bottom of the pan, it would be best dislodged during the main first drain, when the flow is fastest. And if there is some glob of dirty oil hanging by surface tension onto the drain hole lip, a little clean oil upstream would force it out. Is it worth it?
