Diesel engines: how to get the best performance?

Even though many countries have declared war on them to make them disappear, diesel-powered vehicles are still alive, especially in pickup trucks. And although it is increasingly difficult to find an SUV equipped with a gasoline engine, the truth is that it is still possible to buy one of these models.

That’s why it’s critical that drivers understand how to operate these engines to maximize fuel efficiency. Juan Barichevich, Director of the Mechanical Area of ​​INACAP, shares valuable advice to obtain optimal energy performance in this type of vehicle.

“Diesel vehicles require specific care to ensure efficient performance” , emphasizes Barichevitch. Firstly, it highlights the importance of regular maintenance, including oil and filter changes, which help keep the engine in optimal operating condition, which in turn has a positive impact on fuel consumption. fuel and the useful life of the vehicle engine.

Another crucial aspect is to maintain tire pressure within the levels recommended by the manufacturer. Barichevich emphasizes the importance of checking the tire pressure label located on the side of the driver’s door, adjusting the pressure according to the vehicle’s load. This practice reduces rolling resistance and, therefore, reduces fuel consumption.

“Avoid overloading the vehicle and Turning off the engine during prolonged stops is also an effective strategy to optimize fuel performance,” adds Barievich. Additionally, keeping accurate records of fuel costs and mileage can help monitor consumption and make adjustments if necessary.

However, all these tips lose their relevance if the driving style is aggressive.

“Forcing the engine into first gear or exceeding speed limits significantly increases fuel consumption,” he warns. Adopting gentle, moderate driving is essential to maximizing fuel efficiency and ultimately reducing vehicle operating costs.

This not only helps improve consumption, but also extends the life of components such as the DPF, a particulate filter installed on almost all modern diesel engines, which is responsible for retaining part of the most dangerous emissions from these engines, and, once they reach their maximum saturation level, they require exposure to high temperatures for a period of time (driving with the engine revved for about half an hour) in order to regenerate and be ready to fulfill their role.

This is why the use of diesel engines for short trips is not recommended, as it negatively affects the projected durability of these types of components designed to perform well during long trips.
