Very helpful info. My engine already has about 20 hours as it is Bulient's old rotary.

I may run a straight weight nonsyn for the first few hours as the engine has set up for over a year. Any other suggestions as what I should do like inject some trans fluid in the spark plug holes, etc? Seems as though there is good compression on turning the engine over.

My local Napa auto parts store
stocks the Amsoil, but I guess I need to get their oil filter as well to
get the better filtration. Pretty interesting. I will probably run it
when I run my engine on the test stand as the plane isn't quite ready
for the engine and I want to do some testing.
After a rebuild, or for a new engine,  Use a name brand straight weight oil in the sump and
if the OMP is not used, premix a non synthetic 2 cycle oil. Run this for the first 2 hours at 2,000 RPM. Cut open the filter and look for bearing sparklies.
 
Change the oil to whatever you plan to fly on. If no OMP is used, premix a synthetic 2 cycle oil. 
The bearings are way oversized for the loads involved. Just about any oil is fine. At airplane RPM stresses are low. I use Redline 40 Wt. synthetic in the dry sump and Redline 2 cycle synthetic as the premix. Shifts are at 9,600 RPM. No lost bearings since 1980.
 
If you start off with synthetic oil in a new engine or fresh rebuild, it will take months of use to break in the pieces. Our best power is on the 4th weekend after a rebuild. With 24 end gaps, the engines gather up combustion debris faster than piston engines. Oil changes should be at least as often as a piston engine.
