Yes Valve Tech is put in on site from what I know. And like an bulk application, you can never be certain how good the mixture ratio is. Because it is not throughly mixed. Most of the Marina's on the lake are using Valve Tech.... I Know because I have asked many of them. Fays, and Anchor are the only two exceptions I know of that aren't adding Valve Tech.
As for mixing the various brands of treatment. If there is an issue There would also likely be an issue of adding to much of anyone of the treatments. Of all the treatments I have seen, all indicate that over application is not harmful. Also knowing some about chemistry, I think what you would find is there are a lot of simularities in these different brands..... In short until I see some concrete evidence, I find it hard to believe that there would be a problem. Unless you filled the tank and added a full treatment of star tron, and a full treatment of Valve Tech, all at the same time. If you regularly use star tron, and use untreated gas like I do, and then stop on the water because you need to, and fill up with pretreated Valve Tech fuel, I don't see an issue.... just don't go add more star tron on top of the pretreated fuel.
