Why is the Mazda CX-4's fuel consumption high?
3 Answers
Mazda CX-4's high fuel consumption reasons are introduced as follows: 1. Insufficient tire pressure: Insufficient tire pressure will increase the contact area between the tires and the ground, increasing friction, which means higher driving resistance and increased fuel consumption. 2. Ignition coil failure: Problems with the ignition coil. If the ignition coil has issues, it may cause some cylinders to stop working, reducing power. However, fuel injection continues as usual without any effect, leading to increased fuel consumption. 3. Engine carbon deposits: Long-term operation of the vehicle inevitably leads to carbon deposits and sludge from fuel combustion. If these deposits and sludge are not cleaned in time, they will cause an increase in the car's fuel consumption.
My CX4 is currently experiencing slightly higher fuel consumption, which I believe is mainly due to driving habits. I mostly drive on urban roads where traffic jams are frequent, leading to sudden starts and stops, forcing the engine to constantly exert more power. Additionally, the SUV's inherent higher aerodynamic drag is manageable at steady highway speeds, but improper throttle control in congested city traffic easily spikes fuel consumption. Another factor is temperature changes—summer AC use increases compressor load, and cold starts require extra fuel to stabilize the engine. Recently, I’ve adjusted habits like using cruise control more and avoiding frequent lane changes, which slightly improved mileage. I recommend fellow drivers focus on gentle acceleration and anticipating traffic to minimize unnecessary fuel waste—it really helps.
After noticing a sudden increase in fuel consumption with my CX4, I realized that poor maintenance has a significant impact. A dirty air filter not replaced in time causes restricted engine airflow, requiring more fuel to compensate; worn-out spark plugs lead to inefficient ignition, resulting in incomplete fuel combustion and waste; low tire pressure reduces grip, making the wheels harder to turn and naturally increasing fuel consumption. Additionally, not changing the engine oil for too long increases engine friction. I recommend checking tire pressure monthly to maintain standard values and changing the oil and filter every five thousand kilometers. Simple maintenance can save a lot on fuel costs—taking a little time to inspect things yourself, like opening the hood to check the filter's condition, is an easy task.
