A well-known diesel problem in the winter: When it gets too cold, the fuel clogs. The cause of this is paraffin, a wax found in diesel. It's not a problem in the summer, but at negative temperatures the liquid wax becomes solid. It crystallizes, and the crystals block the fuel filter. The result: The motor stops receiving fuel and comes to a standstill.
So take the appropriate precautions and make sure your motor stays fit – even in the icy cold: Diesel Flow Fit increases the flow and filtering capacity of diesel fuel and makes it winter-proof at up to -31 °C (depending on the diesel fuel quality). The additive secures the operation of all diesel-operated motors at low temperatures.
But be careful: You will only achieve the optimum effect by putting the additive into the fuel tank before the fuel starts to clog. And be sure not to store Diesel Flow Fit in the car between uses.
