)The bottle does not give any kind of info at all
It only says :
use 500ml per 50 litres
don't add any other additive together with it
don't keep the ADD 1 in a hot place
That's it. They are bloody secretive I suppose. I had never used it in smaller quantities because at the track I really want the best for my engine (and also for my enjoyment
). My HKS mechanic told me that I could use half the recommended amount for everyday usage but I never tried. For everyday usage, I use cheaper stuff with satisfactory result (as the HKS booster is really expensive).
