Soybean oil is used in a wide range of lubricant and functional fluids applications:
Gear oils and lubes
Chainsaw bar oil
Compressor oil
Two-cycle engine oil
Metalworking oils and
Wire rope, chain, and cable lubricants
General purpose and penetrating lubricants
Transformer and transmission line cooling fluids
Greases - automotive, machinery, rail curve, track
Food-grade, industrial, and elevator hydraulic fluids
Obviously this is a backwards example (food-grade oil used for non-food applications), and my question was using this plastic oil for food applications.
Fascinating and makes sense. I've recently gone down a rabbit hole on the uses of linseed oil pre fossil fuels, but it's too gummy to ever be used as a lubricant. Do you know off hand which seed oils were used for lubricants?
Haha that's amazing! Hopefully the pilots weren't too phased. Thanks for sharing
Did some further digging and it looks like it does have a tendency to gum. From wikipedia, "The viscosity of castor oil at 10 °C is 2,420 centipoise,[28] but it tends to form gums in a short time, so its usefulness is limited to engines that are regularly rebuilt, such as racing engines. Lubricant company Castrol took its name from castor oil."
Protip: if you're ever looking for some downvotes when bringing up the dangers of PUFAs, recommend that people read the book Deep Nutrition.
There seems to be an animalistic hatred toward a book that really sheds the light on why eating industrial waste is not the healthiest thing in the world.
