Interestingly I'm using the Vaporates- really undecided as to whether they work or not.

One thing I do know works- local made oil & fuel additive- my mates VT gen III changed to their oil and literally saw .4l/hr difference in idle fuel usage. Checked before and after- before 2.0l/hr. After- 1.6l/hr. Checked within 1 hour- 1 1/2 hours of each other first late morning second just after 12

that's 20% difference just from changing the oil

fuel additive- similar story but closer to 10%

I think some things do work but you've gotta be careful
