Oil pumps are usually self priming and positive displacement.
Theoretically you should be able to lift up to 37.7 feet with 9 oil at a .9 specific gravity - assuming the reservoir is vented to atmosphere.
Your limiting factors will be the net positive suction head required (NPSHR) for the pump - which accounts for the losses in the pump and the frictional losses from flow in the suction line.
Not likely a problem if your suction line is at least the size of the pump suction and reasonably short. A smaller dia. line will restrict flow and decrease the net positive head available (NPSHA).
Oil does not have a vapor pressure at normal operating temperatures, so you should not have cavitation in the pump.
