'Tain't the same thing, of course, but Mobil recalled it's synthetic
aviation oil because of problems in air-cooled Continental and Lycoming
4-bangers. I don't remember the details, but I seem to recall there
were some issue with cam wear or some such.

Now, the aircraft engine isn't a VW, and it probably works harder, but I
think I'd be wary.
