I use Valvoline 0W-20 full synthetic and an OEM filter.
I used to run the 10w-40 Valvoline high mileage synthetic blend from Walmart.
I use conventional 20W-50 VR1 for oil, love it.
Idemitsu to both, because it’s designed and tested on rotaries.
As a Shop owner that Services a ton of Euro Cars we pretty much use all the Valvoline Euro Spec'ed Oil. They meet all the OEM requirements as we've also sent it in for testing. I have a 2014 CC APR Stage 3+ and thats what I run, Valvoline 5W40 Euro. No Issues.
I use idemitsu rotary 20w50
I stick to Idemitsu. I have a Sohn adapter fitted, so it's 10-30 Idemitsu in the engine, twice a year and Idemitsu Premix in the Sohn adapter and in the fuel tank.
Valvoline vr1 20w50 I'm convinced they basically make it for rotary's to begin with.
I've been using the valvoline personally and like it better than the pennzoil platinum.
Used this for years in my 4 strokes. Quality oil.
