(Disclaimer - I make and sell a plant oil mixture for clarinets and guitar fret boards and genuine Grenadilla Oil)
Very interesting discussion.

Just a few facts scientifically proven:

Wood does gain and loose moisture. In drying environments wood shrinks and rings get loose, add moisture in the environment and the wood expands and rings tighten. Oil content is also measurably reduced in hot dry environments. Plant oils bind water tightly and buffer water loss in Grenadilla wood.

As I have written in the past - a mixture of plant oils labeled with a fluorescent lipid molecule and applied to the surface of a piece of Grenadilla wood for 24 hours can be visualized by a fluorescent microscope looking at a thin section to penetrated deeply into the wood. Different oils or oil mixtures pentetrate at different rates. Most plant oils, if not protected by antioxidants, will turn rancid from autoxidation forming acidic products whcih can harm wood.

Analsyis of wood artifacts hundreds of years old yield some common results of oils used in pereserveation and museum conservators use some common formulations of oils in present day conservation of wood artifacts. All of these oils are of plant origin.

One customer, the largest seller of Grenadilla oboes in the US, gives a vial of Grenadilla oil and instructions for oiling with new oboes. His results over 5 years and several thousand oboes is a 25% reduction in all returned oboes for cracking. How this oil is used or not used is not important given the sample size with the only variable being the presence or absence of the oil. Of course oboes and clarinets are not the same animal.
