Changfas' and Synthetic Type Oils

[OilCan]

Any opinions on the use of synthetic or semi-synthetic type oils in the Changfa engines.  My main
concern is seal compatibility.  Not sure if their use would cause premature leakage.  For now I have
only 12 hours on my engine and that is using Rotella.

Shell makes a Rotella synthetic also. I am running it in my Changfa with no apparent problems.
I also run the Rotella synthetic in my Ford 7.3L diesel (3 years).
