After receiving my trial bottle of Fueltone I proceeded to dose my colleagues Lexus 220D which was lacking power and had low mpg. We have tried various additives including Protec. Forte, Redex etc with very little to no improvement. We dosed the tank with Fueltone and took for a good run. He is now experiencing an improvement in power throughout the rev range and a considerable improvement to his mpg. Happy to come on as a stockist.
