The term “short-volume oil change” (SVOC) relates primarily to circulating oil systems. An SVOC occurs when an oil change (either scheduled or condition-based) only involves draining and refilling the oil in the system tank or sump. All or some significant portion of the oil remaining in the oil lines, hoses, bearings, pumps, filters, actuators, valves, heat exchangers, etc., is not changed. In other words, it is a partial oil change.
