Oil System
The R8 engine uses a dry sump lubrication system. This
system includes an external oil pump, cooler, and tank.
There are a few advantages of having an external pump:
the engine is placed lower in the vehicle because the
oil pan is smaller, oil starvation does not occur, and the
pump can be replaced much more easily than one of a
wet sump system.
