Use 20W-50. It's a thicker oil, and thus won't break down under the extreme heat of the rotary. Also, remember that the engine is oil cooled, so you don't want super thin oil that turns into water when it heats up.
10W-30 if it's really cold, 20W-50 otherwise.

When oil gets hot is has a certain thickness and it has a different thickness when cold. Your engine was designed with a certain amount of space to allow a ceretain thickness of oil to pass through for max performance of part and longer life. All engines when built should use this tool Its called PlastiGuage. This allows for clearance for oil on surfaces where needed.
If your running thicker oil your actually getting lets oil to the surface being its thicker moves slower and it too thicker to fit between the clearance.
Oil lubricates by moving fresh oil to the hot surface, the more flow the better, not heavier the better, being its getting hotter breaks down faster and is allowing for wear during start up and driving.
Just do what the factory says.. 10-30...

Mr. Eccentric-we agree-The 5/30 created to protect piston engines under normal driving conditions as well as a minimal increase in fuel mileage which all manufacturers are looking for. Combination of 10/30 (winter) & 20/50 (summer) you can't go wrong.
Used plastigage extensively along with micrometers to measure rod and main bearing clearances on piston engines when rebuilding.

20- 50 is only good for a worn out engine, as it has enough clearance to allow the 20-50 to get in and do its job...
I have ran 20-50 in my car I live in southern Florida. All 20-50 did was make the car rev slower and killed some power, and got worse mileage, than 10-30.... my .02 cents...
