oil temperature

I covered one row of fins on the oil cooler and was able to get the temperature up to 200F on climb and about 180F at cruise; is this an acceptable temperature for continuous operation?

After covering up one row of fins on oil cooler I was able to reach 200F on climb out and cruise at about 180F (see photo of cruise data).

Safe for continuous operation at these temps?

In my opinion it's still a bit cool.

Try for over 100 C(212 F) + on CO & mid to high 90C (194 F) in Cruise.

Remember to cover a bit of the coolant radiator as well as the oil cooler/radiator.

There are three systems that should work together;

Coolant Radiator

Oil Cooler/Radiator

Cooling fins on cylinder barrels

Covering the coolant radiator is not an easy task, as it requires removal of lower cowling.  As temps fluctuate this would be a real challenge.  The issue is getting the moisture from combustion out of my oil…if I can get the oil temperature up to where the moisture cooks off, what other issues am I missing?

Considering a Thermostasis oil temperature control unit; anyone have experience with this?

Joseph,

"The issue is getting the moisture from combustion out of my oil…if I can get the oil temperature up to where the moisture cooks off, what other issues am I missing?"

It's not just removing the volatile fractions (inc water) it's also about optimum operating temperature for the oil.

"Covering the coolant radiator is not an easy task, as it requires removal of lower cowling."

Like you I must remove the lower cowling to partially cover my coolant radiator (& my oil cooler)is a pain in the derriere however if you start with my suggested 1/3 covering, you will quickly find out if this is too much or too little and adjust accordingly.

Consult with other pilots (using the same engine) in your climate zone. My understanding is that fitting such a device (added weight/complexity/cost) is of particular application in cold climates. In New South Wales, Australia,  the cost effectiveness is doubtful😈
