Vaseline has turned out well for me too. I know the old Singer motor grease was a saponified grease, in very old tubes you can see it some times has separated when bit of oil is seeping out. This quality still exist but it's very hard to find in reasonable sized tubs or tubes (Würth has one in a large bucket size container). It's very easy to find a synthetic grease with teflon / PTFE these days (like Triflow). They turn out very well in more advanced friction tests and work well on open meshing gears like the Featherweight and 201 have. I guess that's why they are widely recommended.
