farbrerio is right. its not that fram filters are bad for rotaries, they're just bad filters...
also, modern synthetics are not bad for rotaries, using synthetics in a 20 yr old motor that ha 100k+miles on conventional is another story... synthetics are detergant by nature and thus "clean" away deposits left by conventional oils that aid in sealing, this leaks can form. this is why alot of engine builders recommend using a quality conventional oil during the break-in period and then switching to a synth if you want (which doesnt make much sense to me since one would think that the deposits would still be swept away?).
also, i dunno how accurate it is but some say that synthetics will cause swelling in seals in old engines as there is a different type of runner used. like i said, i dunno about that part. im no chemist

Non synthetic;
Castoral GTX 10W30 or 20W50....the 20W50 is for summer and track days when the engine is going to be running warm for long periods of time.

Get an analysis, it's not expensive < tells you exactly what you have/need. And actually all modern oils are pretty close.
And an oil temp gauge. that will tell you what you ought to be running. Too thick it'll get too hot, too thin it gets too cool.
You will find Rotella is the shiznit
