lol thats a can of worms you just opened.
IMHO stick with what the car was meant to have 10w40 mineral oil, no disrespect to Gary or RP oils (I have used them in Skyline GTR\'s to great success) but I dont trust synthetic in a rotary.. I have never had a problem with 10w40 76 racing mineral oil and last time my engine was apart everything was clean as hell, unlike some of the engine that had run on synthetic oil. For the definitive view talk to Tim at RX Motors as he\'s done more engines than anyone else in the UK.
