Yes, there are several mechanical faults that can significantly increase fuel consumption in Hyundai Elantras in Pakistan. Faulty oxygen O2 sensors can send incorrect data to the engine control unit ECU, leading to a fuel-rich mixture and poor mileage. Dirty fuel injectors are another common issue, especially when low-quality o r adulterated fuel is used they affect proper fuel delivery and spray patterns. Malfunctioning thermostats that fail to bring the engine up to optimal operating temperature can also result in higher fuel use, as the engine remains in cold start mode longer. All these issues may not be immediately obvious but can be detected through diagnostic scans and regular servicing.
