I do, in fact, think that it is completely disingenuous to make any claims about tests run at 1:250 when your recommended ratio is 1:500. In my old fashioned book that's the same as telling a lie.

I viewed the link in your message, however, it seems they have posted an error in their copying of the Standyne bulletin to their page! I have checked the original Stanadyne flyer, part number 99300, and the sentence where they mention the "1:250" is not in the original factory information. It states, "... Both ran DF-2 diesel fuel, one had Performance Formula added at the recommended treatment ratio. "Both ran DF-2 diesel fuel, one had Performance Formula added at the recommended treatment ratio". I do think that it would be disingenuous to misrepresent any test data. I do not think that is the case here, just simply an error on Diesel Injection Services website... Let me know if you need a copy of the bulletin. I can e-mail it...
