Hello, What do you think of such additives for diesel fuel against spillage? (Diesel Flow Fit by Liqui Moly)http://www.zentalverkauf.de/a/30478104/src/goo/Vehicles/lubricants-and-%C3%96le/DIESEL-flie%C3%9F-fit-Liqui-Moly.html ….Since the diesel engines have really hard in the winter and add very low temperatures to the diesel fuel, I wonder if such additives are a good thing, if not for me this is an argument not to buy diesel. For the next winter should remain as extreme as the last winter and if the driver already has to fight with -30 degrees, then at least the engine of the car should not strike. …….The “construction market” additives for diesel should not be good, but how about additives from such manufacturers as Liqui Moly? (see above)
