Now that people are starting to question the corn based ethanol boondoggle, this makes less sense than ever. Maybe you can lace soybean oil with enough antioxidents to keep it from polymerizing for a while. I still don't think an inherently unstable material is a good starting point for motor oil. Certainly nothing you would ever want to use in an extended OCI.
I am not part of big oil or in cahoots with anybody else here.
labman, if you truly are, I'd recommend looking at the science.
Oxidative stability for vegetable oil is obtained in two ways. First by genetic engineering of the crops.

Vegetable oils are mainly consumed in foods. However, they also serve as the primary
feedstock for the oleochemical industry and are gaining popularity as lubricating base oils.
Vegetable oils are obtained from renewable resources and are biodegradable. Thus, they
offer specific environmental benefits over mineral oil-based lubricants. In addition to
environmental benefits, vegetable oils also have certain performance advantages over
conventional mineral oil base stocks. These include low volatility, high flash points,
viscosity index, and excellent lubricity. The primary drawback of conventional vegetable
oils is their lower oxidative stability relative to mineral oils and certain synthetic esters.
However, with recent advances in breeding technology, it is now possible to alter the
physical properties of conventional vegetable oils by changing fatty acid profiles. A
specific example pertaining to lubricant applications is the improvement of oxidative
stability by increasing the oleic content in various oils.
Second, with stabilizing additives:
Quote:
During this R&D program, many years of studies were conducted with many different
additives. It was discovered that the patented anti-oxidant chemistry (identified in patents
#1, #2, and #3) reduced oil thickening and deposits significantly in vegetable base oils at
extreme high temperatures over 1500 to 250 0 C, where most other known additives will
dissipate. Examples of areas that the chemistry would show the vegetable base lubricants
increased performance is in the high temperature and close tolerance areas of the top ring
of a combustible engine, turbine bearings, or a hydraulic shifting valve operating close to a
heated injection unit. Other areas would include high temperature areas in need of
increased fire safety as in casting and steel mills etc. XXX’s technology with HOBS have
shown exceptional performance in high performance racing engines, and when combined
with other proprietary additives, develops an increased synergistic effect in anti-oxidant
and anti-wear performance.
