I installed new rings in my motor. They are Gas ported moly coated .038 D shaped top ring. I'm used to .031 dykes rings with a "mirror" finish on the walls. With this setup just starting the motor and idling broke the rings in.
Now I'm using a rougher finish, and different ring (described above). Do I need to cycle them in before switching to synthetic oil? Or can I just use the dyno oil in the garage. Then change it and go run it?
