Gerotor pumps are nearly unaffected by heat and oil viscosity and do not lose oil pressue.
Nearly every race motor ever made uses one or more gerotor oil pumps.
The Merlin oil pump return is so efficient that it not only increases the oil supply and scavenging in the motor, it also improves the breathing system and increases horsepower.
Increased oil flow through the motor means less heat build up and less engine wear.
