Your oil might still appear black after a change due to residual buildup in the engine that did not get removed during the oil change process. This is especially common in older engines or those that haven't had regular oil changes. To mitigate this, consider using an engine flush before your next oil change to remove sludge and buildup, and ensure regular oil changes moving forward to maintain engine cleanliness and performance.
