I recall that quite a few years ago when I last read a Holden Owners' Manual it said that the use by owners of any kind of fuel additives is unnecessary, and is discouraged because it 'just adds to running costs'. I also recall that in the early days of port fuel injection the oil companies were a bit slow to put injector cleaner in the fuel as a standard component; instead they were peddling bottles of the cleaner as an additive to be used by car owners. At least one car manufacturer objected because their tests showed that the injector cleaner was prone to stripping the tern plate off the inside of the cars' filler necks. Of course the oil companies then began putting the cleaner in all of their fuels as one of their standard additives.

Far be it from me to say anything nasty about somebody's commercial product sold in good faith, but I personally won't be putting that product in the tanks of my B&S engines.
