Oil temperature

[GuppyWN]

Limited info on the search function but is 180 an acceptable oil temperature? I taped half the oil cooler and the oil temp reached 200 but the cylinder temp was pushing 215.

I don't see anything wrong with those temps.

Jim,

The 180 oil or the 215 cylinder? 220 is my indicated redline so I’m a little nervous taping as much of the cooler as I did to get the oil temp to 200.

you are from boise, no way that's a problem. leave it alone. I have a thermostat on my oil and I think it keeps it 180. I've flown over 2000 hrs with that and have never seen water in my oil. I'm just north of you a couple hundred miles. leave it and go fly.

The experts say 180 is the minimum temperature needed to remove water form your oil. The oil temp is actually getting hotter elsewhere in the engine, that is why 180 works. I would say 180-200 is ideal.

Which engine do you have? The 912ULS CHT max is 275F. The 912UL CHT max is 300F. Oil temps between 190F and 230F are normal. The Rotax 912 operating manual is the source for those numbers.
