Thats considered a fine operating temperature.

I once fitted an oil cooler without a thermostat and it kept oil temps to about 80deg, and caused my oil to go like mayonnaise.
The oil needed to get to a higher temperature to evaporate the moisture.
I dred to think the long term damage it would of caused  :stupid:

100-120 degrees is acceptable. I had issues with oil temp on my 135i, switching to 10-50 oil has helped.

If the temps get too high then the oil gets too thin and cant lubricate.

James, what oil do you use?

Yes.  Go to a 5w40 competition oil.  You should notice the temp drop slightly too.

I would recommend the Millers cfs 5w40 nt.  Running this in my car and loads of others on here are too.  Highest temps I saw at a brunters track day was 110.  On the road I'm usually around 90.
