I read the document and his numbers are very interesting, but there is a big problem with his cost numbers, he does not include the cost of his products needed to treat the fuel, so overall fuel cost would likely be higher when his product cost is factored in. However, it might be lower if you consider maintenance and longevity issues, so I would have liked to have seen a full cost benefit analysis in the paper.
Another issue is that the author seems to have products that are bulk sold and vended to given industrial platforms, not consumer grade products. This is fine for his target of fleet managers, but for us consumers, it's of less value.
A true triple independent lab analysis of all major additive products on the market would resolve the issue to most people's satisfaction... Anyone aware of such a blind, independent study?
