Liqui Moly Pro-Line Diesel System Cleaner – 500ml

Keep your diesel engine running like new with Liqui Moly Pro-Line Diesel System Cleaner – a high-performance solution designed to clean and protect the entire fuel system. Whether you’re driving long distances, hauling heavy loads, or commuting daily, diesel engines build up deposits over time that can hurt fuel economy, throttle response, and emissions. That’s where this powerful additive steps in.

Formulated in Germany with precision-engineered chemistry, this cleaner is suitable for all diesel engines – from passenger cars to commercial vehicles. It works by removing carbon and other stubborn deposits from injectors, fuel lines, and the combustion chamber. The result? Restored fuel atomization, smoother engine operation, better cold starts, and reduced smoke and emissions.

But it doesn’t stop there. Liqui Moly Pro-Line Diesel System Cleaner also adds a lubricating layer to protect the injectors and fuel pump, preventing premature wear and extending the life of your fuel system. It ensures cleaner combustion, which means your engine runs quieter and more efficiently – with a noticeable improvement in throttle response and power delivery.

This cleaner is simple to use. Just add the contents of the can to the diesel tank before fueling up. It gets to work immediately, making it ideal for preventative maintenance or restoring performance in high-mileage engines. One can treats up to 75 liters of diesel fuel and is safe for use with turbochargers and diesel particulate filters (DPF).

Backed by decades of German engineering and trusted by mechanics worldwide, Liqui Moly is a name you can rely on for premium car care. Pro-Line Diesel System Cleaner is part of their professional-grade series, making high-quality automotive maintenance accessible to everyone.

Whether you’re a mechanic, car enthusiast, or everyday driver looking to improve your engine’s health, Liqui Moly Pro-Line Diesel System Cleaner is your go-to solution for long-term diesel engine care.
