In my opinion, this Liqui-Moly-remedies is a blast! I did it for the first time mixed in this harsh winter at -20 ° C together with the Flow Fit K from the same manufacturer in the diesel fill-up. The effect was quite simply amazing. (Also compared to many cited in the Internet 2-stroke oil admixture in diesel as an additive!) Nailed the diesel before even minutes painful and mechanically hard to himself, so he already jumped shortly after admixture when re morgentlichen cold start so so silky smooth, as if someone overnight, the high-pressure injectors and the diesel pump on my car (VW 1, 9L unit injector TDI changed with DPF). Even in the hot summer, the car runs not feel soft.
I am firmly convinced that fell significantly (particularly in the cold start phase) the mechanical stress. Documents, I can not, of course, but any doubts, I can only recommend a try with this tool! The effect is really set torque !!! Imagination excluded! I, for one, will therefore add it regularly.
Returns default is ranked still lower than the petrol-Super-diesels at astronomical prices, of which no one could convince me so far as this additive together with standard diesel. A negative impact (eg increased demand regeneration of the diesel particulate filter, etc.) so far I could not identify. Five stars is therefore fully justified!
