Liqui Moly Speed Tec Diesel – 250ml

Liqui Moly Speed Tec Diesel is a high-performance diesel fuel additive designed to enhance engine efficiency, restore lost power, and provide smoother acceleration. Formulated in Germany, this advanced additive brings cutting-edge fuel technology right to your diesel engine, whether you’re driving a rugged SUV, a high-mileage truck, or a daily commuter.

What sets Speed Tec Diesel apart is its unique ability to improve combustion. It works by optimizing fuel atomization, which allows diesel to burn more thoroughly and cleanly. This not only boosts power and responsiveness but also reduces fuel consumption and emissions. The result? A noticeable difference in performance — your engine runs smoother, starts more easily, and responds better under load.

One of the standout benefits of this additive is its ability to enhance the driving experience immediately after use. Users often report a faster throttle response, more torque at low RPMs, and quieter engine operation. It’s particularly effective in cold climates, where diesel engines often struggle with ignition and lag. Speed Tec Diesel also helps to prevent deposits from forming in injectors and combustion chambers, which means longer engine life and fewer maintenance issues.

Designed to mix seamlessly with all types of diesel fuel, including low-sulfur and bio-diesel blends, Liqui Moly Speed Tec Diesel is also safe for use in vehicles with diesel particulate filters (DPF) and turbochargers. With regular use, it supports engine longevity by maintaining the cleanliness of critical fuel system components and minimizing wear and tear caused by incomplete combustion or carbon build-up.

Easy to use, each 250ml can treats up to 75 liters of diesel fuel. Just pour it directly into the tank before refueling, and let the additive get to work instantly. Whether you’re a daily driver, a commercial vehicle operator, or an off-roading enthusiast, this product delivers noticeable results in both short-term power gains and long-term engine health.

Made by Liqui Moly, a trusted name in automotive lubricants and additives for over 60 years, Speed Tec Diesel reflects the brand’s commitment to quality, performance, and innovation.
