Perhaps you misunderstood. I mentioned Yamaha because that's the source of the goo. It happens that it's Yamaha spec for their racing engines and can be had at the dealer. Obviously someone else mixes it up.
Those $40K to $50K engines that the boutique shop builds are Continentals and Lycomings that are bolted on in such a way that the propeller is forward of the vehicle. Your "$12,000" Continental would cost about $20,000 coming from this shop and well worth it. Let's please not turn this into a Marvel Mystery Oil discussion.

My concern is in the difference in design and application. Yeah, the racing Yamaha engines may be $50,000 each and our lowly Continentals are only around $12,000 each so I'd expect the Yamaha people would choose the absolute best for their application. But their application is days or weeks (probably not months very often) sealing-while-inactive and then minutes or a very few hours of horrendous stress. Ours is weeks or months (sometimes years) of sealing-while-inactive followed by hours of moderate stress. The Yamaha recommended gunk may be the best on Earth for our application. Or, it may be something that turns to powder with a few years of age. I don't know and I have no means of knowing and that's my point. Ed
