Wondering if the engine is getting hot and is not being adequately cooled causing the heat from the engine block to be passed through onto the oil.
Is the radiator fan working?
I am assuming that there is the correct level of coolant in the system - check the level in the overflow reservoir when the engine is cold.
Are the water pump and coolant thermostat working OK?

To check the water pump and the thermostat, with a COLD engine, apply the handbrake (emergency brake) and engage the transmission in Neutral (manual trans) or Park( auto)

To check the water pump and the thermostat, with a COLD engine, apply the handbrake (emergency brake) and place the transmission in Neutral (manual trans) or Park( auto)
Next remove the radiator cap and then start the engine.
Observe the coolant in the neck of the radiator.
BE SAFETY AWARE _ THE ENGINE IS RUNNING!!
After a while as the engine warms, at a preset temperature (set by thermostat), the coolant will start to swirl (or flow) in the neck of the radiator.
This indicates that the thermostat has opened and that the coolant pump is working, pumping the coolant through the engine.
Be careful as the coolant will expand as it gets warm and will want to flow out of the neck of the radiator.
Turn off the engine as soon as you detect movement in the coolant and securely replace the radiator cap.
If the coolant doesn’t start to flow, '''turn off the engine''' and feel the 2 hoses connected to the radiator. One should be hotter than the other. This indicates that either the thermostat didn’t open or that the pump is faulty.
Try removing the thermostat (see YouTube videos for your model) and check if it is OK.
If it is then the water pump is next on the list :-)
