If I were shilling, I would expect to get paid for it. But I do not. I happen to believe that most of what Todd does at Project Farm is well-thought out, thorough and technically sound, as well as practical and useful. I also have seen a lot of data on Amsoil, including chemical analysis, as well as more than a few anecdotal stories about how well their products work, which also matches my own experience with their products. I note that the chief detractor of both of these organizations on this forum has been quite cagey about what his supposed college degree is. I suspect it is not in science, technology, engineering or math, as he does not seem to have a clue about how science actually works.
