engine oil

I am not happy with the oil temperature on my 1UZ: I have a relatively big Monster radiator with two powerful Bosch thermostat controlled fans. I am using the red anti freeze fluid in black plastic cans, Toyota pre mixed coolant. There is between 10 and 11 liters of coolant in the system...
