The EPA in America do tests on all sorts of fuel additives and devices and so on. Fascinating reading: https://www.epa.gov/vehicle-and-engine-c...it-devices
They have a summary page here: https://www.epa.gov/vehicle-and-engine-c...it-devices
I think basically they say that, in years of testing, have never found anything that makes any marked improvement to fuel economy when it comes to devices/additives.
Even people you would think would know better get taken in. Peter Brock famously promoted his polariser device: https://en.wikipedia.org/wiki/Peter_Brock
