Generally around 15 years. The lifespan of the engine is closely related to routine maintenance. Using high-quality engine oil, air filters, oil filters, and fuel filters, regularly replacing coolant, ensuring no water shortage, maintaining normal temperature, avoiding high-speed driving, and not overloading are crucial. Below is relevant information: The D4D diesel engine offers over 30% better fuel economy compared to gasoline engines and reduces CO2 emissions by nearly 45%. The D4D diesel engine can guarantee a driving range of 150,000 kilometers without requiring replacement, thereby lowering vehicle operating costs. As for the noise of the D4D diesel engine, drivers equipped with sound insulation and noise reduction technology can hardly notice any significant difference compared to gasoline engines. To date, the D4D diesel engine has been continuously developed, not only overcoming many drawbacks of diesel engines but also being widely used in various Toyota models due to its high torque, high reliability, excellent fuel economy, and low pollution.
