    You'll be fine for 2021 from the original certification of your plane in the US. 2020 is all, but gone. 2021 is almost here. You're welcome to come to Tucson anytime you want. The huge majority of my clients come from all over the US from coast to coast.

    Glen.  As a multiple science degree holder, your explanation is by far the most erudite and correct that I have seen regarding the vapor pressure of water and the misconception of requiring boiling point temps to facilitate water removal from oil.  This will be helpful for others to read.  I have read that engine efficency is better at higher tempeartures, as well as bearing lubrication.  I think these were the issues I am most concerned about.  In the past Roger has said to keep oil temps above 190 F.  The recommendation for coolant temps have never been clear to me.  Do you know of any Rotax generated  engone efficiency curves as a function of temperature which are available for the 912?
