The use of advanced additives (so-called nanotechnology) during engine maintenance can certainly improve not only performance but also the engine's efficiency, while preserving its wear characteristics. A preliminary inspection before maintenance shows that, despite the low mileage, the engine has already begun to exhibit a slight loss of compression.

Begin by adding an additive to the diesel fuel (the fuel filter replacement for this model is recommended around 31,000 mi and it is a relatively expensive filter) and one to the oil before draining, allowing it to circulate for about 15 minutes. Then proceed with the oil and filter replacement, adding another additive.

Subsequent measurements of the same parameters already show an improvement.

How to reset the Service light on a 2019 Jeep Renegade?

The Service light, depicted as a yellow spanner, illuminates as scheduled to remind the driver that it is time for scheduled maintenance. This means that the set mileage has been reached, or the expected time has passed. The procedure involves turning on the instrument cluster, pressing the accelerator three times, and then turning off the ignition. After this, keep the brake pressed, turn the ignition back on, and then turn it off again. Upon the next ignition, you will notice that the light has been reset.
