Who knows maybe when I learn more about it and see some actual testimony from people I trust, not marketing hype, and results I can verify, I might give it a shot.
If you are worried about contaminants, you should learn how the refinement process works. All of that stuff won't make it and using recycled oil produces a higher quality base stock than conventional. Recycled oils are going to be Grp III base stock for the most part. I think that is why you'll see the prices a bit higher for it.
