So do not use a synthetic lube of any kind in the assembly of a rotary unless you are using the seals over again, then by all means use synthetics everywhere. . New seals means no synthetics until after break in.

I have no personal contact with Mobile one, but early in its production there were some problems. Now it is good enough for Corvettes. What pour weight to use I do not know. I used 40 and 50 weight Redline because it pours like lighter fluid. Not a single oil related problem.

What is the current feeling on mobile 1 and if positive what weight and should it be used for break-in?

Then 40 or 50 weight Redline racing oil. Never over 180 degrees on the coolant.  Then a lap at part throttle then good for 9,600 RPM at full throttle. No oil related failures in 35 years of racing.

You could do 4 hours at 2000 RPM no load or part load on fleet oil. Should be plenty. Never over 180 degrees.
It worked for me...............Lynn E. Hanover

Less than 4000RPM for the first 600-1000 miles.

I don't see that happening. I don't think I can keep the RV-4 level at
less than 4,500 RPM, depending on prop.

And I sure want full power at takeoff and climb to pattern altitude.

I guess I could run it on the ground for 10 hours at varying RPMs below
4000, but really?

What did you do with a new Renesis?
