The manufacturer considers 1 kg/cm^2 or 98 kPa or 14 PSI normal oil pressure at 800 rpm.
At 5000 rpm normal pressure is 3.0 kg/cm^2 or 294 kPa or 43 PSI.
These numbers are MINIMUM acceptable pressure; readings can and will be higher.
Definitely expect higher pressures at cold startup.
I don't use a gauge but have seen 2.0L motors exceed 100 PSI on startup, and exceed 75 PSI during normal use.
