why would you not be able to use synthetic motor oil in the rotary engine? my dad and his co-workers forumulated the leading synthetic and one of the nonsynthetic motor oils out there (you can probably guess which one) and he tells me that there should be ABSOLUTELY NO reason that synthetic would not be better or equal to nonsynthetic for this car or any other.
in fact, most synthetics out there are actually a blend of nonsynthetic and synthetic motor oils, and chemically the only difference is that synthetic contains less particulates and debris. SAE grades both types of oil identically also, and you can mix the two at will w/o any adverse effects (besides lowering the boiling point and raising the pour point).
If anyone knows a GOOD reason for not allowing synthetic motor oil other than "the manual says so" please tell me.
