The Fuelstar product brings about a more complete and more controlled combustion. In turn, this results in reduced fuel consumption and/or increased power output (normally 10% and more) Reduced emissions of diesel black smoke, particulates, nitrogen oxides and 'greenhouse gases'. Cleaner engine oil, thus improved lubrication and cleaner internal engine operating surfaces. Revention of valve seat recession in at-risk engines. Reduced pinking & detonation in engines.
