I think that I am getting it.now . What you are saying is to use 1/2 oz/gal  poor quality crank case oil per gallon as a pre-mix and not use the standard pre-mix oil at all during the break-in. (am I close?)

Thanks for bearing with me.

Len, just to clarify,

Do you mean to put an additional 1/2 oz per gal conventional oil in the already added premix (about 1.5 oz total pre and conventional oil?).

Additionally in a newly overhauled engine do you still recommend the water technique to get rid of the carbon created by the break-in period of the oil mixture.

Additionally additionally is standard oil miscible with both pre-mix and fuel?

Additionally additionally  and as well---Do you think that the water treatment should be done periodically and if  so how often?  When I rebuilt my motor after only about 14K the rotors had significant carbon (which was a bit#h to remove.) perhaps to do the water as a prophylactic treatment.

Thanks again again, again
Rich

Cheap conventional oil in the premix at about 1/2 ounce per gallon as well as in the crank case. The round rings are oil scrapers and are supposed to keep crank case oil out of the combustion chamber, same as a piston engine. Do not tell anybody about this.......with a warm engine at 2,000 RPM...slowly add 1 cup of water to the intake over several minutes. It will remove all of the carbon from the rotor face and free up sticking apex seals in most cases.  Works on piston engines as well....like MAGIC. Saves hours of scraping.

Since the bearings, bushing and eccentric shaft have been relatively untouched, (14K on engine since rebuild) it seems as synthetic in the case would be OK however, the rotors seem to have different needs on break-in
