Abstract
Equipment for draining and refilling the lubricating oil sump of a motor vehicle comprises a large capacity main oil reservoir. Inlet means to the reservoir from the sump include a vessel which is evacuated to suck oil from the sump and pressurized to cause the oil to flow into the reservoir. Oil rejuvenating means are included in the inlet. Means are provided for discharging a metered dose of oil back to the sump from the reservoir.
