The reasons for the check engine light coming on in a 2018 Ford Focus could be due to a malfunctioning oxygen sensor or excessive oil consumption. It is important to eventually replace the oil in your car, typically recommended every 5,000 to 10,000 miles. Neglecting to change the oil can lead to engine problems, so it is crucial to use high-quality oil for a smoothly running engine. Using bad oil may cause the engine to fail, resulting in issues such as a strong burning odor. It is necessary to address these concerns promptly to prevent any potential dangers, including the risk of the car catching fire. In addition, poor oil quality could also lead to poor gas mileage and engine knocking sounds.
If the check engine light is illuminated on a 2018 Ford Focus, it indicates that the engine is experiencing difficulties, which could lead to issues such as poor acceleration, failure to start, rough idling, and other related problems. It is important to address this immediately to prevent any further issues with the vehicle.
