J&J is highly refined mineral oil, but mineral oil comes in various grades, so it isn't necessarily the best option. Also as I said the additives are at least as important as the base stock. Just as not all carbonated water is beer, not all oils have the same lubricating properties.
So far my problems with vegetable oils are their lack of water resistance, and their stability over long periods exposed to weather. That can and will change, but don't expect that any one naturally occurring oil will magically have the desired properties. It'll be used as a base, and things added to improve the film strength and/or water resistance, resistance to breakdown or rancidity, adhesion, etc.
BTW- keep in mind that mineral oil is a relative new comer, only being around for 150 years or so. Prior to that animal and vegetable oils and fats were the only game in town for multiple millennia.
Also keep in mind that "green" products aren't always as green as they seem. There's been a big rush to bio fuels and bio lubricants. In the short term it's driven up food prices, and led to deforestation in the tropics to harvest products such as palm oil. Eventually there will be an equilibrium, but the current headlong rush is proving that Kermit is right and it isn't easy being green.
