In the engines that have been in operation for longer periods, the indicated
values can be lower by about 10%. For instance:
At 2000 RPM: Min. oil pressure 2.0 bar (oil temperature 110°C); if oil
temperature is higher, oil pressure will be lower
At 4000 RPM: Min. oil pressure 2.9 bar (oil temperature 125°C); if oil
temperature is higher, oil pressure will be lower
At 5500 RPM: Min. oil pressure 3.3 bar (oil temperature 135°C); if oil
