The majority of vehicles manufactured around the world come with wet sump lubrication systems where the oil is contained in the pan and is circulated by an internal pump generally driven off the camshaft. Some engines, like the Chevrolet LS, feature a crank-driven oil pump.
A large number of race cars and high performance street machines feature dry sump lubrication systems where the oil is contained in a remote sump tank and circulated with an externally-mounted pump that’s belt-driven.
And then there’s a “hybrid” setup that uses a remote oil sump tank, an externally mounted pump to evacuate the lubricant from the pan, and the OEM oil pump to supply the pressure. This is a popular way to overcome the shortcomings of the factory LS lubrication system.
