Boyd, again, no oil expert here, but oil weight aside, I've seen a lot of people on the boat forums expressing concern over the lowering of zinc additives in many of the oils traditionally popular in the boats. This is something that has happened in the last few years. For folks with flat tappet cams like you and me, the consensus is that it is something we don't want to go without. Many have mentioned Chevron Delo, Royal Purple or Valvoline VR1 as brands that have maintained acceptable ZDDP levels for our motors. I know there are others, but I can't call them up right now. If straight 30 weight oil works for you, great. But check those ZDDP levels, too.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
