I know of several CSX4000's that are using
synthetic of one brand or another, all the owners are satisfied with the
synthetic oil performance. I think the statement the FE engines are not well suited to it's use is unjustified.
As for using it for break in, after my engine was rebuilt, I didn't use it, I wanted my rings to seat before hell froze over. But many many manufacturers do put it new engines, again with great results, as they can control tolerances to the degree necessary for ring break-in not to be a factor.
