The base HFRR in the two samples I referenced above were 636 and 425. That's a huge spread. If the "average" diesel we're getting is more like 425 adding stuff could be pretty much useless, on the otherhand if it's more like 636 it could be really helpful. And if it's all over the map, an additive is cheap insurance.
