First, synthetic oil is perfectly fine for rotary engines. Despite the bad information being parroted for the last 15 or so years, ad nausium, in a properly tuned engine synthetics cause less carbon buildup than mineral oils. Anyone who wishes to dispute this, please provide an accounting of how many thousands of engines you've dissasembled and evaluated, and how many of those were running synthetic vs. mineral oil. We've been using synthetics for perhaps 15 years now and recommend them to all our customers.

That said, it is a totally different question whether you should switch to synthetics. The answer is probably not. Synthetics may prevent wear better and last longer, but they can't reverse wear and thus are a waste on an older engine. Turbo rotaries, especially, have a tendency to dilute the oil with fuel (a solvent) and that means you don't even get the benefit of the extended oil change interval. Non-turbo rotaries can at least double (or more) the interval, though you still need to change filters at the usual time. But, all said, it's really not worth using synthetics in any engine with any consequential mileage...say, 50K+. I'm not sure I would even bother on an engine with 20K. Mineral oils are very, very good if you change them religiously and also very affordable. Of all the things to worry about, it's at the bottom of my list.
