    Just a quick question, haven't asked a dealer but thought i would try it here.... Is there a break in period you should run your equipment (ztr's mainly) before switching to using a semi synthetic or full synthetic like there would be with a car? Just wanted to get some of your thoughts on this and when a good time to use synthetic would be? Of course it is going to matter on the machine so lets say a Exmark Phazer with a 19kawa motor. Any thoughts?

    usually 5 hours break in on regular oil then switch to synthetic, make sure you change oil filter after 5 hours too

    MartinsMowing is right, use regular oil first, then drain and switch to synthetic or a synthetic blend.

    The moving parts need to break in (read wear against other parts) before you switch to synthetic oil. Synthetic can almost stop moving part wear, but in a new engine that can lead to galling of the machined surfaces which is bad.
