The reason I was more concerned at this point, is that at the end of August I am taking the RV6 to S France for two weeks, where currently it is +30c !! There are no cowl flaps and the inlet at the front is quite small compared to a Piper or Cessna.
Quite right to be concerned.
Last month near Bordeaux (33deg) the 360 in our Piper Arrow was nudging the red in the climb to FL70.
Felt it prudent to level off for a while to see oil temp drop.
