Morgan makes that fuel and their specialty seems to be airplane fuel and not necessarily car fuel. I was doing some digging around on the internet and didn't really see anyone mention anything about their car blends. I believe I saw something about them using a synthetic blend and that's not something I'm after. I know Byron's had one of the best, if not the best, oil package for off the shelf fuel and it was spoken of in high regard on several forums over the years. S&W appears to use a premium oil package so I'm going to probably reach out to see about their custom blends.
