Well they claim 100,000 miles which in my Austin 7 is like infinity.
"These thingies" which are tin amalgam chunks have been on the market for a considerable time. I have, over the years, researched such information that I could find regarding SCIENTIFIC PROOF that these things actually did any good. I could find no authenticated evidence that these products are anything other than a scam with advertising carefully worded to avoid making any claims that might result in prosecution. If this junk was any good every car manufacturer in the world would put some in the tank of every new car sold.
Only my opinion but, save your money, it's another version of "snake oil".
Yes, these were discussed in the first year of my own engineering degree and I was struggling to remember the argument against them but then realised there isn't one, because there is simply no science to argue with.
