i like the idea of putting my brand engine oil in right off the get go.but i guess i'm gun shy after reading dino oil seats the rings better but for the life of me i can't understand how an oil that does not lube as well can seat rings better just can't understand it,now not ever luging the engine and not over revving the engine during break in makes perfect sense to me
Here is what I understand. Builders can chime in to correct, as may be necessary.
With a new build, the jugs are freshly honed. That means that they have been finished with a non-glazed, fine cross-cut finish. This virgin finish allows the brand new rings, which are true, but not specifically fit for your jugs, to wear just enough to fit to your specific jugs. At the same time, the cross-cut finish on the inside of the jugs is smoothed to match the rings. It is a mutual adaptation of jugs and rings. Once the micro-fitting of rigs to jugs is done (seating), initial wear of both tapers off to what will be the case for the life of jugs and rings. The first 50-100 miles is the critical time, during which, the fitting wear will occur. You change the oil out after that period to eliminate the micro-particles, that come primarily from the inside surface of the jugs.
If you have really slick lubrication during the first critical period, the necessary fitting will take longer. Is the difference between the consistent molecule size of synthetic lube and the more random Dino lube enough to significantly affect the ring seating period? Possibly not. One thing for sure, you do not want to run the engine at consistent loads and rpms during the initial period. You want as much variation in those 2 inputs as possible, so you do not seat for any specific set of conditions only.
Here is incentive for initial Dino lube: You are going to thow away your full tank of oil after 50-100 miles. You want a decent oil in there? or an expensive one? I suggest you put in an adequate one, then put in the good stuff later, when you can keep it.
As Dolt said, "It is your ride. You get to decide." You won't kill your machine either way. Dino is less slick. Break in will be faster, but maybe only just. Synthetic is slicker, break in may take longer, but maybe not detectably. A Dino/Syn blend will be in between there, somewhere. How you ride her during the break-in period is the absolute most important variable, over which you have control.
Enjoy,
