I am currently using Aeroshell 15W-50 (per the install manual). But the Maintenance Manual says that in the heat of a Las Vegas summer, I should be using a 120 weight oil? I change the oil and filter every 25 hours but am concerned about cooking the oil. Now add to this, one of the Jabiru Engine distributors that I spoke with at Oshkosh this year says that they are recommending switching to a straight mineral oil. Possibly a Phillips brand but my brain lost that point (maybe I'll find it later).  I am running the oil cooler that came with the FWF kit. It's a Long brand oil cooler measuring approximately 11" wide by 2 7/8" tall by 1 5/8" thick with 12 plates and suppose to handle 7500 BTUs. So my questions are" 1) what are other flyers in hot environments using for their engines? 2) does the factory have any suggestions?

As a follow-up to this, I just got an email from Nick at Arion Aircraft (Flylightning.net). He says that they are now using, and recommending, Phillips 20/50 XC. That it is a multi-weight oil but NOT a synthetic. Apparently Jabirus do not like synthetics because they are hard on the rings that they use.That I could also use Aeroshell 100 or 80 straight weight with no problem. And he mentioned that a mineral oil is required for the Breakin Period.
