The diagram below indicates normal temperatures against RPM.
The minimum permissible oil pressure is a function of the oil temperature and
RPM.
See diagram below (applies to engines when new)
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
temperature is higher, oil pressure will be lower
