If I had to guess I would say that the Protek R is simply repackaged two
stroke oil.  Cameron at Pettit is a pretty bright guy, but I doubt that
he has the knowledge to discern exactly what is required in a turbo
rotary as opposed to a two stroke.  A chemist he is not.  As for the
recommended mix ratio, keep in mind that it is meant to be added in
addition to the oil that the stock metering pump supplies.
