LIQUI MOLY Super Diesel Additive 250ml

What Is LIQUI MOLY Super Diesel Additive?

LIQUI MOLY Super Diesel Additive is a diesel fuel treatment developed to clean and maintain the diesel injection system and combustion chamber. Its combination of cleaning, dispersing and protective additives helps remove existing deposits and prevent new deposits from forming.

Diesel injectors play an important role in fuel delivery and combustion. Deposits can affect injector performance, fuel atomization and engine smoothness. Super Diesel Additive helps maintain clean injection nozzles, prevents injector needles from sticking or becoming gummed up, and protects the fuel system against corrosion and wear.

The formulation also increases the cetane number of diesel fuel, improving ignition quality and supporting smoother engine operation.

How Does Super Diesel Additive Work?

LIQUI MOLY Super Diesel Additive is poured directly into the diesel fuel tank, where it mixes automatically with the fuel.

As the treated diesel circulates through the fuel system, the additive helps clean deposits from the injection system and combustion chamber. Its dispersing properties help prevent further deposit formation, while its protective components support the cleanliness and durability of fuel-system parts.

The cetane-boosting properties improve diesel fuel ignition quality. The additive also increases the lubricating effect of low-sulfur diesel fuel, helping reduce wear in fuel pumps and injectors.

Key Features and Benefits

• Cleans the diesel injection system.
• Helps remove deposits from the combustion chamber.
• Helps prevent new deposit formation.
• Keeps diesel injection nozzles clean.
• Helps prevent injector needles from sticking and gumming up.
• Increases the cetane number of diesel fuel.
• Improves diesel ignition quality.
• Supports smoother engine operation.
• Provides corrosion protection.
• Improves fuel lubricity, particularly with low-sulfur diesel.
• Helps protect fuel pumps and injectors against wear.
• Suitable for conventional diesel and biodiesel fuels.
• Compatible with diesel engines with or without DPF.

Suitable Applications

LIQUI MOLY Super Diesel Additive is suitable for all diesel engines, including:

• Diesel passenger cars.
• Diesel SUVs and 4×4 vehicles.
• Common-rail diesel engines.
• Turbocharged diesel engines.
• Diesel vehicles equipped with DPF.
• Commercial vehicles and vans.
• Tractors and construction machinery.
• Stationary diesel engines.
• Compatible engines using conventional diesel or biodiesel.

The product can be used preventively to maintain fuel-system cleanliness or as a treatment when deposits are present. It is also suitable for low-sulfur diesel fuels.

Product Specifications

Application and Dosage

LIQUI MOLY Super Diesel Additive is added directly to the diesel fuel tank. It mixes automatically with the fuel and does not require a separate cleaning procedure.

Recommended application:

1. Check that the product is suitable for your diesel engine.
2. Open the vehicle’s diesel fuel tank.
3. Pour the additive directly into the tank.
4. One 250ml can treats up to 75 litres of diesel.
5. Refuel if necessary and drive normally.

The recommended mixing ratio is 1:300. For preventive fuel-system maintenance and injector cleanliness, LIQUI MOLY recommends adding the product approximately every 2,000km.

For preserving an engine during extended storage, the manufacturer specifies a separate 1% dosage. Follow the official preservation instructions for this application.

Why Is Diesel Injection-System Cleaning Important?

A clean diesel injection system helps maintain proper fuel delivery and combustion. Deposits around injector nozzles can interfere with fuel atomization and may contribute to rough running, reduced performance and increased emissions.

LIQUI MOLY Super Diesel Additive helps remove these deposits and prevent new ones from forming. It also helps prevent injector needles from sticking or becoming gummed up.

Its cetane-boosting properties improve diesel ignition quality, while its lubricity-enhancing components help protect fuel pumps and injectors, particularly when using low-sulfur diesel fuel.

Protection Against Corrosion and Wear

Fuel-system components operate under demanding conditions. Corrosion and insufficient lubrication can contribute to wear in fuel pumps and injectors.

Super Diesel Additive helps protect the entire fuel system against corrosion and wear. Its lubricating properties improve the protection of fuel-system components, while its cleaning action helps maintain injector cleanliness.

This combination makes it useful for preventive maintenance as well as treatment when deposits affect fuel-system performance.

Why Choose LIQUI MOLY Super Diesel Additive?

LIQUI MOLY Super Diesel Additive combines diesel injection-system cleaning, deposit prevention, cetane improvement, lubrication enhancement and corrosion protection in one product.

It is suitable for a wide range of diesel engines, including modern turbocharged vehicles and engines equipped with diesel particulate filters. Its 250ml can treats up to 75 litres of diesel, making it convenient to use during normal refuelling.

For drivers who want to maintain injector cleanliness, improve diesel ignition quality and protect fuel-system components, Super Diesel Additive provides a practical fuel-tank treatment.

Important Usage Information

• Designed for diesel fuel only.
• Do not add to petrol, engine oil, coolant or transmission fluid.
• Follow the recommended dosage.
• Keep the original container closed and follow the safety instructions on the label.
• Store safely away from children and ignition sources.
• This additive supports fuel-system maintenance but does not replace mechanical repairs or professional injector servicing.

LIQUI MOLY Super Diesel Additive 250ml is a diesel fuel treatment that cleans injection-system deposits, increases cetane number, improves fuel lubricity and protects fuel-system components against corrosion and wear.
