Re: [Amel Yacht Owners] Diesel fuel problems and additives

I used to be very involved in two cycle lubrication a couple of careers ago and was wondering what "two stroke" oil do you use? The formulations for hot running air cooled two cycle engine lubricants are very different to cooler running water cooled (outboard) motors. The latter are designated TC-W for "two cycle water cooled" on their packaging. The air cooled stuff will create gum and varnish at the lower temperatures of a water cooled engine. The result can be disastrous, very quickly.
Similarly, all TC-W oils are not created equal. The ones sold by the motor manufacturers Mercury, Yamaha, Johmson, Evinrude etc. are of a uniformly high quality because their poor performance will reflect unfavorably on the brands. Major oil companies products are usually OK but you cannot be sure. As usual, it ibecomes a cost issue.
By the way, most of your litre is a diluent to thin it down so it will mix with the fuel. It used to be a kerosene type product but who knows what is today. In short, there is not much "oil" in outboard "oil" but it sure can make a mess.
I'm hopeful you are using a product that expects to get burnt in the combustion chamber and not stick the rings but, for what it's worth, my strong preference/practice is to use the outboard manufacturer's products when oil-fuel mixing is required.

Bill, great question and I think the answer is “never” since the engine was rebuilt in 2010. I’ll put it on the top of my list. The staining isn’t very bad, but still annoying. Thanks!
