Which brands suggest waiting that long to use their product?
Red Line, Bel Ray, Miller's among others last time I checked. I would tend to stay away from an oil that has higher, >15%, ester content until you know you have good ring seal. Why tempt fate.
Q: CAN I BREAK-IN MY ENGINE ON RED LINE MOTOR OIL?
For performance engines, we recommend using conventional 10w30 motor oil to ensure proper piston ring seating. We recommend using this oil in combination with our Engine Oil Break In Additive, which features the antiwear chemicals necessary to protect valve train components like camshafts, rollers and tappets. Though most conventional oils are missing the important antiwear components that you find in Red Line's synthetic motor oils, the conventional oil is not as slick as Red Line and will allow the piston rings to seat more quickly. If you allow 1500 to 2000 miles in a street engine or 20 to 30 minutes on the dyno at low rpm, the rings will have had sufficient time to seat and the high initial break-in wear will have occurred. For new road cars, always follow the manufacturer recommendations and initial oil change recommendations for break-in.

Thanks for that information!
