When I lived in WY, I used Sun Oil DCA-11. This is a Dust Control Agent that the mines would spray on the roads to keep the dust down. It was also soybean based. It was less than $4/gal if you brought your own buckets. It worked great. I did not have any problems with it going rancid. Now I live in WA and am unable to find it cheaper than the mineral oil. Maybe you can check in to it and see if they are using an additive to keep it from going bad.

Thanks for the suggestion Jerry, I'll check into the DCA=11 and see if I can find out what kind of stabilizer they used in it. Robert.

Have you tried filtering the soy oil for reuse? If it all has to be tossed when the oil is changed the the cost would be higher than mineral oil, I can filter out and reuse about 80% of whats in the saw at every oil change, which with $18.00 a gallon oil would be equivalent to $3.60/gal oil that gets thrown away. Also have you tried it with opalised wood or any kind of common opal? I have noticed that common opal seems to like to fall apart when cut in oil and I'm considering switching a larger saw to a different cutting fluid

Hi Lee, I haven't tried cutting any opal with the soy oil, although I do have some jasper that is highly opalized out in my rock pile. it's not pure opal and it has too many fractures in it to actually use as a test material. As far as filtering the oil, this batch already smells like pop corn,so I really don't want to save it, but I guess I could try filtering it just to see what kind of recovery I get. Anyway! I would assume that once I find the right kind of stabilizer to add to the oil, it should be recoverable like mineral oil. This is still my first batch of soy oil, so I probably have a few more months ahead of me to figure out the pro's & cons of using it as my primary cutting fluid. So far it looks like it has potential as an alternative to some of the other oils.
