And, in my experience, there is no such thing as "the oil gets too cold". Shortly after T/O, I set prop pitch to coarse, engage carb heaters at 5500 ft - with these actions, my oil temps were fine all the time.

Ok. I thought I saw some connection between engine failure and low oil temp but if I understand you correct then the crucial thing is the engine temp which I should try to keep between 200 and 250?

Could you confirm this...
- Open rads lowers engine temps (and vice versa)?
- Activated carb heaters raise engine temps (and vice versa)?
- Throttling up i.e. higher rpm raise engine temps (and vice versa)?

How does coarse pitch affect the temps? I mean, lower rpm gives lower temp but coarse pitch give higher load on engine.

I ment wheel brakes. Sorry.

Thanks!
