I don't think you will ever get far away from a petroleum product.
'Petroleum product' is a pretty broad term.

Greases (at least conventional ones) are a mixture of an oil (usually petroleum) and a soap (often lithium). It would be interesting to see exactly what the Singer grease is, or even if it's not actually a grease (like petroleum jelly for instance).
