Re: Synthetic oil?

If synthetic oil reduces friction and wear it should be especially advantageous in a long stroke engine. They are known to be at a disadvantage at today's higher road speeds because of higher piston speeds and greater load on the rod bearings than a short stroke engine. Synthetic oil should help such an engine more than a modern engine in terms of increased power, smoother cooler running and long life.

The down side seems to be synthetic's ability to creep past seals and gaskets. Possibly a newly rebuilt engine with modern seals and gaskets would be ok.
