Too early to review yet as to whether it lives up to its claims. Really needs to be used over a few thousand miles, i.e. several tanks full, before one can get a true answer to that question. But this website wont take any comments if I don't include a star rating so the start rating above is not based upon actual product delivery against its claims. HOWEVER IN TERMS OF EASE OF USE OF PRODUCT THIS PRODUCT DISAPPPOINTS - measuring out the correct dosage (and perhaps more importantly pouring this, once measured, in the separate measuring section - red cap in pic above) is very much less than ideal, or a simple task; and can be quite laborious and result in either wastage of product or over mixing/over concentration of product in fuel.
