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.
The fans start at about 92/93 degree celsius.
The coolant temp is steady between 90 and 94 degrees celsius.
I am happy with that.
I have fitted a relatively large Monster oil cooler.
The place the cooler is fitted is not great. Its right behind the engine
so the cooler doesn't get much of a natural air flow.
To compensate for low natural air flow I have 5*25Watt fans mounted on the
back of the cooler, (fans running all the time).
There is about 5.5 liters of Toyota fully synthetic 5/40 in the system.
When running at about 2000-2300 rpm the oil temp is below 100 celsius (just).
When increasing rpm to 2500 and a bit above the oil temp goes to 105 and above. I don't like that.
Now, what would you guys say that the oil temp ought to be be?
Am I completely on the wrong track when I expect the oil temp to be close to the coolant temp?
