Why is the MG 5 so fuel-consuming?
3 Answers
The reasons for the high fuel consumption of the MG 5 are as follows: Affected by temperature: Temperature fluctuations can cause variations in fuel consumption. In winter, lower temperatures generally lead to increased fuel consumption. Vehicle not serviced for a long time: Dirty engine oil and air filters can also result in higher fuel consumption. Contaminated oil leads to poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, thereby raising fuel consumption. Excessive carbon buildup in the vehicle: Carbon deposits commonly accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas can cause incomplete combustion, leading to increased fuel consumption.
As an owner who drives the MG5 daily, I think its high fuel consumption might be related to my driving habits. I'm impatient and always love to stomp on the accelerator to overtake, which causes the engine's fuel consumption to skyrocket, especially in city traffic with frequent stops and starts—the fuel gauge just drops rapidly. The MG5's engine tuning is quite sporty, responsive but particularly fuel-hungry at low RPMs. I have a monitoring app installed in my car and found that fuel consumption can double during hard acceleration. Running the air conditioning frequently adds extra load, and a fully packed trunk increases resistance due to the added weight. To mitigate this, maintaining a steady speed of around 80 km/h on highways is the most fuel-efficient. I've also learned to control my foot and press the accelerator more gently, using the S mode less often. Regularly checking tire pressure and engine oil is also crucial. My experience shows that developing a smoother driving habit can help reduce fuel consumption somewhat.
From the car itself, the fuel consumption factors of the MG5 lie in its design. Its sporty styling results in high aerodynamic drag, leading to significant wind noise and increased fuel consumption at high speeds. The 1.5T engine is aggressively tuned for power, but its efficiency drops in traffic or at low speeds, naturally resulting in poor fuel economy. The transmission in my car shifts slowly, often keeping the RPMs high, which consumes more fuel. The car is not lightweight, and choosing wider tires increases rolling resistance, further adding to fuel consumption. I believe the manufacturer prioritized driving pleasure over fuel efficiency—while this was acceptable when the car was new, system degradation becomes noticeable after a few years. To improve, I opt for Eco mode in the city and use cruise control on highways to optimize resistance. I also keep the car light by avoiding unnecessary cargo. During maintenance, I ensure high-quality oil changes and clean air filters, as these factors should not be overlooked.
