I used to used heated canola/veggie oil to quench small to mid sized blades and tools before I found a source for the engineered (and in my opinion, much superior) quenchant I was after (parks #50). The parks quenchant may not be as green, but it lasts a heck of a lot longer, is much more consistent, and just works better overall.
Sure, canola might be less than 1/3 the price per gallon of an engineered quenchant, but when you have to buy 5 times more of it by the time you're done, for less than optimal results, the engineered oils pay for themselves over and over again.
