Thanks, calebd and marthur for weighing in. And thanks to whoever fixed the title line, I could not find how to do it.

I have heard about the synthetic being too slippery for the reversal gear and did not intend to use that. My usage is quite standard, a Chesapeake day and weekend sailor. Neither Michigan ice sailing (though I make my season longer than most Chessie sailors; in by April, out by December or not at all, but the boat incl. motor is winterized at the first serious frost) nor tropical heat.

As you say, I cannot see why 10W30 would be harmful at this point. I am just concerned why Don Moyer (whom I consider the world's premier authority on all things A-4) said it is Ok to use 10W30 'in a pinch.' I wonder if he reads this forum?
