30 wht. non det. petrolium oil. Break in cam dump oil Refill with same. Run to operating temp and cool completely for about 6 times. This is to allow (work hardening) to pistons which will harden the soft alu of the piston and become harder than before and scrub the rings to the cyl. After that you can go to a better oil
(syn, or petrolium) and hammer down. Good luck. GEO
