1. Engine Damage: Red diesel has different chemical composition compared to regular diesel fuel, it contains higher levels of sulphur and other impurities. These impurities can cause accelerated wear and tear to the engine components, including the fuel injectors, fuel pump and other engine parts. The higher sulphur content can lead to the formation of sulphuric acid, which can cause corrosion of metal parts and damage the engine over time.
2. Reduced Performance: Red diesel might have lower energy density compared to regular diesel, which can result in reduced power and efficiency of the engine. The engine might exhibit sluggish acceleration, loss of power and reduced fuel economy when using red diesel.
3. Emissions and Environmental Concerns: Red diesel typically has higher emission of particulate matter and nitrogen oxides than regular diesel. This can contribute to air pollution and negatively impact the environment. Using red diesel in a road vehicle is illegal and can result in fines or legal penalties.
4. Fuel System Issues: Red diesel might not contain the necessary additives that are present in regular diesel, such as lubricity improvers and detergents. These additives are crucial for the proper functioning of the modern fuel injection systems and the health of the engine. Prolonged use of red diesel can lead to issues with fuel injector clogging and reduced fuel system performance.
5. Warranty Issues: Using red diesel in a vehicle can potentially void the manufacturer's warranty, especially if the manufacturer specifically prohibits the use of alternative fuels in their vehicles. It is important to check the vehicle's owner manual to confirm the recommended fuel type and potential consequences of using alternative fuels.
Therefore, it is strongly advised to avoid using red diesel in your Renault Laguna 1.9 TDI and stick to regular diesel fuel from a reputable source to ensure the longevity, performance and emissions compliance of your vehicle.
