This product is an efficient additive specifically developed to optimize the low-temperature flow properties of diesel. It rapidly lowers the diesel's cloud point, effectively refines wax crystals, and reduces the cold filter plugging point, further improving the low-temperature flow properties of diesel. It possesses excellent low-temperature dispersibility and fluidity, along with good resistance to oxidation, corrosion, and high-temperature cleanliness. It effectively prevents high-temperature oxidation of the oil and corrosion of pistons.
