Porsche 911 GT3 RS User Handbook Manual page 27

The oil pumps are designed so
that there is negative pressure
in the crankcase. This reduces
resistance to the movement of
the pistons to improve power
output and efficiency. Another
pump in the crankcase supplies
the lubricating points in the
engine from the external reser-
voir.
For the engine this means consis-
tent lubrication of the crankshaft
assembly and the two cylinder
banks, even under very high lateral
and longitudinal loads which are
possible with sport tyres.
The new 911 GT3 RS and the 911 GT3 |
The 911 GT3 and the new
911 GT3 RS are factory-filled with
Mobil 1 high-performance fully
synthetic oil. Its exceptional
lubricating properties ensure
reliable starting even in the
coldest conditions and, impor-
tantly, contribute to the long-term
durability of the engine
