Purpose and Specifications

LIQUI MOLY Super Diesel Additive 250ml is a professional-grade fuel system cleaner designed for all diesel engines. This additive removes harmful deposits from fuel injectors, valves, and combustion chambers while protecting your entire fuel system from corrosion and wear.

What it does:

• Cleans fuel injectors and prevents nozzle gumming and sticking
• Increases cetane number for smoother, quieter engine operation and easier cold starts
• Boosts fuel lubrication, reducing wear on fuel pumps and injectors
• Protects against rust and corrosion in fuel lines and tanks
• Reduces fuel consumption and exhaust emissions
• Safe for diesel particulate filters (DPF) and catalytic converters

Dosage: One 250ml bottle treats up to 75 liters of diesel fuel (mixing ratio 1:300). Simply pour into your fuel tank—it mixes automatically.

When to Use / Replace?

Add this additive to your diesel tank every 2,000 km (approximately every 1,200 miles or monthly for average drivers) for optimal fuel system cleanliness and corrosion protection. Regular use keeps your injection system in perfect working order and minimizes operating costs.

Compatibility: Suitable for all diesel engines—cars, trucks, tractors, and turbocharged engines. Works with conventional diesel and biodiesel fuels, including low-sulfur varieties.

Storage: Keep in a cool, dry place. Shelf life is standard for fuel additives when stored properly.
