Probably didn't explain myself too clearly!
Obviously based on science as Redex will be using quality scientists to stay top of their game for so long.
Will work reasonably well for an older style engine; decoking rings etc.
However what I alluded to as Foo, on much more modern designs, all the sensors pretty much are doing the same job. Self cleaning etc.
I would think, servicing on schedule, quality oils and filters with good long runs to stop gummy build up of carbon deposits negates the need for additional foo!
