In addition, it is essential to routinely inspect the oil level and change the oil as recommended by the manufacturer. This will ensure that your engine’s oil pressure is within the recommended range and that it is operating efficiently. The best method to preserve your engine’s long-term health and performance is to adhere to a regular maintenance program.
