I used off the shelf TCW III in my KA-37 and it seemed OK as the motor itself is in great condition internally. I did manage to pick up a liter of aviation oil while at the airport recently but I want to try it in a worn Light Four to see if it will improve the running characteristics over the TCW III oil. It will be getting used sparingly as it cost over $10 per liter!
