No, had you read my earlier post(s), I am involved with the development of vegetable-based and bio-synthetic lubricants which means any and all types of vegetable and other GroupV oils.
On this site, one has to start out with the basics and then later get into the details and maybe even add some chemistry.
Further transgenic varieties of
brassic napus have produced better rapeseed varieties with lower Euracic acid content and higher oleic and linoleic acids. Currently, there are 10 different transgenic varieties of
brassic napus

In fact, most industrial canola is simply oil that hasn't been refined enough for cooking use.
The comment I made about cooking oil was to differentiate common cooking oil from that used in lubricants.
Some time ago there was this ridiculous Urban Legend/rumor going around about Canola's toxicity, but genetically modified rapeseed (Canola) has lower Euricic acid than rapeseed.

If you have something to add regarding vegatable-based lubricants and the formulation of those lubricants, please elucidate.
The genetic modifications which make oil from the canola-modified strains of
Brassica napus produce less erucic acid do so by stimulation the creation of oleic and linoleic acids. Common cooking grade canola is termed "50% oleic" referring to the ratio of oleic acid to other acids present in the oil, rather than the overall amount of oleic acid in the oil. Commonly available "industrial" canola is termed "75% oleic". This is the primary difference between chemically-extracted varieties of canola and the variance is caused by some of the oleic acid being removed by the additional refining, cooking, and bleaching done to chemically-extracted canola oil to remove the toxic hexane that was used to extract the oil form the seed and "enhance" the color of the oil for consumer use (much like yellow dye is used to enhance the color of butter, though the color doesn't affect the quality of the product so much as the perception of quality).
Cold-pressed canola does not introduce hexane into the oil, therefore does not require the same refining process. As a result, cold-pressed cooking-grade canola will commonly contain 75% or more oleic acid, putting it squarely in the realm of "industrial grade". In fact, when compared to "industrial" variants of chemically-extracted canola, "cooking-grade" cold-pressed canola is the preferable preferable industrial lubricant, due to the lack of hexane contamination.
I feel like you're making some unfounded assumptions about me, so allow me to correct them now; I may have joined a little over a year ago, but I've lurked much, much longer, and these forums are not my only exposure to the wonderful world of lubricants, or to the chemistry involved. Specifically, I am quite familiar with the synthesis of esters; mostly vinyl esters used in composites, but we may or may not have made our own air tool lube and mold release coatings with the same "chemistry set" in that shop.
So, why don't I whip up my own brew of esters to add to my oil? Simply put, because that's not the point if my experiment; the point is to determine whether off-the-shelf canola can be a viable source of mix-in esters for those who don't want to spend $100 for a sumpfull of an off-the-shelf ester-based oil, let the additive pack in an off-the-shelf ester-based motor oil battle it out with the additive pack in whatever host oil they choose, or drop $30 for a bottle of ARX.
Am I advocating this for anyone else's engine? No, I have no data to back it up at this point. That's the point of the experiment; to gather that data and present it here. Your word simply isn't going to be good enough here, and you've been here long enough to know that. Since you've stated that you have a horse in this race, your credibility is further placed in question. That said, I'm curious about your product, as I'll need something to move on to once my current experiment is done.
