Diesel Fuel in the Winter

On an extremely cold day,paraffin,one of the chemicals in diesel fuel,may separate from the diesel fuel.This separation makes starting the engine difficult.During the winter season,Kerosene is added to diesel in the domestic market to prevent the paraffin separation and secure stable flow of the fuel through the fuel filter.The amount of added Kerosene into diesel can vary by location and their average winter temperatures.Therefore,to ensure an easy start on a cold day,park your vehicle inside of a garage.if possible,fill up the fuel tank after each driving to prevent ice from forming inside of the fuel system.
