Way over my head... https://docs.google.com/viewer?url=patentimages.storage.googleapis.com/pdfs/US7927387.pdf
The link is for the patent of a fuel additive for both gas and diesel, if I read correctly. I didn't think that was possible based on what I have read, that being that cetane improvers reduce overall octane, and vice versa. I don't think the formulas would apply anymore, ULSD has come on board since the patent, and any additive pretty much has to be tailored for the base fuel.
I know from personal experience (read that experimentation, and/or ignorance) that I put 4 ounces of a diesel additive (cleaner/ cetane improver) in about 3.5 gallons of RUG, and within about 35 miles, that engine was pinging under even light acceleration. I haven't heard spark knock in a long time, pretty much since EFI became common. Topping off the tank and the ping stopped within a few miles.
Taught me two things, don't do it again, and 1 ounce per gallon of some fuel/add combos can have a dramatic effect on end result. This was a concentrate, supposed to be used at about 100:1 in diesel.
