Purpose and Specifications

LIQUI MOLY Pro-Line Super Diesel Additive is a premium fuel system cleaner designed for all diesel engines, including those with turbochargers, particulate filters, and catalytic converters. This 1-liter bottle treats up to 300 liters of diesel fuel at a 1:300 ratio, delivering powerful cleaning, lubrication, and corrosion protection to keep your engine running smoothly.

It removes deposits from injectors, valves, and fuel lines for better combustion, boosts the cetane number for easier starting and less knocking, and provides essential lubrication to reduce wear on pumps and injectors. The formula works with low-sulfur diesel, biodiesel, and even HVO fuels, ensuring reliable performance in cars, trucks, tractors, and heavy equipment. Stable from -36°C pour point for cold starts to 63°C flash point, with effects lasting up to 2,000 km per treatment.

When to Use / Replace?

Add directly to the fuel tank after repairs, during inspections, or preventively every 2,000 km or every other refueling in commercial vehicles. For long-term protection during storage or extreme conditions, use with every fill-up to prevent gumming, rust, and costly injector replacements. Shelf life exceeds 3-5 years when stored cool and dry; one bottle covers multiple tanks for ongoing savings on fuel and maintenance.
