I used to use vegee bar oil, better for the environment I think, and washes out of clothes. Then when it became mandatory to use it for the prefectural falling contracts, they absurdly jacked the price way up. It used to be actually cheaper than petroleum based. Standard oil used to make a great product that I bought from one of their depos in Sonoma County. It was a petroleum based oil that had a tack agent in it, I think the anti sling oil was designed to be used in certain types of machinery. It was sold in like twenty gallon buckets and was super cheap, not a reclaimed oil either. I have tried to get the number of that product, no name just a number, to recommend to you guys, but can never come up with it searching on the web. I wish that someone could ask Standard oil about it, which of their oil products has a tack agent in it? Who knows if they still make it, but it worked so well. Maybe if you can just get a tacking agent substance, you could add it to canola.
