You never want to use a synthetic with a rotary engine from Mazda. It actually has to burn oil so it can lubricate the Apex seals in the engine. Synthetic is more resistance to burn off and there for causes a very high failure rate in their motors. Conventional or Mazda's specifically engineered blend can be used.
IIRC, Mazda itself backed away from the "no syn" directive a good number of years ago. I doubt that they'd be selling this if they hadn't. Note the language on the can (FULL synthetic for the Renesis (rotary) engine).
