Don't most manufacturers recommend going a step up in oil content and only using natural oil during break in? Then the pilot can switch to synthetic at the recommended mixture if he wants to. As I understand it, the natural oil will dissipate heat faster and let the ring seat faster due to not being as good a lubricant.
