Wow. What an accomplishment. Congrats.

I'd heard oil needs to see 212f minimum at some point so that it can boil off moisture that develops. Such a terrible problem to have eh?

I have have about 5 hours on the plane since the latest updates and I find that even using moderate levels of boost in climb, Coolant temps peak at 80C (176F) in a prolonged climb and cool to 60-70C (140-160F) in cruise even at 180KTAS. Oil runs only slightly warmer in prolonged steep climb as high as 94C(200F) but it also quickly cools to the 60-70C range in cruise.

Besides unnecessary drag, is there any problem with with continuous temps that low? Someone wrote that oil temps in particular should not be that low and will tend to cause sludge. My oil temps have always been that low, and I wonder if that may have contributed to my stuck side seals x2. I use mobile-1.
