Rad temperature on green but oil temp up

Howdy
Since 2 weeks ago when I changed the clutch disk oil pressure is up even after 20 minutes of driving (close to 7/8). Strange thing is that radiator temperature stays down in green. I assume both gauges are working correctly. I have emptied and refilled the radiator and changed the cap just last week. Oil is in full (although filter has not been changed since 8000km ago). Any idea what is causing this?
tx a bunch in advance

First off, change the oil and filter - you may have a clogged filter kicking in the bypass on the filter housing.

Secondly, if electric gauges and LR original check the voltage regulator behind the paneland make sure it's doing what it should - falely high readings are not at all unusual for those gauges.

Thank you.
