Just watched the video and checked the website - I fully agree with your view Dave.
If the oil is fairly good it should work, but if there is a high amount of FFA I would be very suspicious of the first stage completion. It does say the oil should be filtered and dewatered - but gives no details on how well (at least non that I saw). It also does not say what strength Sulphuric acid to use which could also lead to problems. The instruction manual (I assume one is supplied) might clarify these points, but as usual all problems are carefully ignored for sales purposes.
