It neutralises the harmful effects of low-sulphur diesel
Lucas Fuel Treatment is formulated for both gasoline and diesel engines, carbureted or fuel-injected. It is designed to address the challenges posed by low-sulphur diesel fuel, which can have adverse effects on engine performance and longevity.
Low-sulphur diesel fuel has been linked to a range of issues in diesel engines. One of the primary concerns is its impact on fuel efficiency and engine performance. Low-sulphur diesel can lead to increased fuel consumption and reduced engine power. This is due to the inherent characteristics of low-sulphur diesel, which can cause incomplete fuel combustion and affect the overall efficiency of the engine.
Lucas Fuel Treatment is designed to neutralize these harmful effects. It contains a blend of oils and additives that work to improve the performance of low-sulphur diesel fuel. The treatment has a high detergent action, which helps to clean and lubricate critical engine components such as the carburetor and injectors. By doing so, it promotes more complete fuel combustion, resulting in improved engine efficiency.
The treatment also helps to mitigate the adverse effects of low-sulphur diesel on engine longevity. Over time, low-sulphur diesel fuel can lead to increased wear and tear on engine components, particularly those exposed to the fuel. Lucas Fuel Treatment acts as a lubricant, reducing friction and wear, and helping to extend the lifespan of engine parts.
Additionally, Lucas Fuel Treatment complies with federal low-sulphur content requirements for diesel motor vehicles and non-road diesel equipment engines. This means that it can be used safely and effectively in a range of diesel applications, from cars and trucks to locomotives and marine diesel equipment.
