I know its not scientific but using some of my old mans wits about proper engine break-in and warming up is key. I dont mean sitting the car warming up, but driving her to warm it up. You should not rev the car while its cold (even if OEM stops you at 6K, its probably best to not pass 4K) and when it reaches operating temps, gradually building RPMs to smooth it out would be the way to go. After that you can drive it hard. Dont drive like grandmama, i am firm believer this is detrimental to any engine, especially with such a thick oil. Dont abuse it but let the RPMs rise as it was designed, but only at operating temps!
I used to drive mine slow and i stopped doing that. Its not scientific stuff but the car is noticably running more even and smooth at mid RPM range since I adopted this style of warming her up. Something is working...
