Why Does the Wuling Rongguang Mini Truck Have High Fuel Consumption?
2 Answers
There are several reasons for high vehicle fuel consumption: 1. Fuel consumption fluctuations due to temperature effects: Generally, in winter when temperatures are low, fuel consumption increases, almost comparable to fuel consumption when using air conditioning in summer. This is because low temperatures cause the engine to dissipate more heat. The warm-up time is longer in winter, requiring more time and gasoline to reach normal water temperature from a cold start. 2. Prolonged lack of vehicle maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty oil results in poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, thereby increasing fuel consumption. 3. Spark plugs need replacement: Spark plugs are often overlooked, with some people not replacing them even after hundreds of thousands of kilometers. When spark plugs reach the end of their lifespan, they may still function but will cause delayed ignition due to insufficient ignition energy, missing the optimal ignition timing. 4. Insufficient tire pressure: Low tire pressure increases the contact area between the tires and the road, leading to greater friction and thus higher driving resistance, which increases fuel consumption. Insufficient pressure also shortens tire lifespan and raises the risk of blowouts during high-speed driving. 5. Incorrect data from certain sensors: For example, the water temperature sensor and oxygen sensor. If these sensors are not completely broken but provide inaccurate data, they may not trigger the malfunction indicator light, making it difficult to detect without using a computer to check the data stream. 6. Excessive carbon buildup in the vehicle: Carbon deposits can accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas can lead to incomplete combustion, thereby increasing fuel consumption.
As a delivery driver who has been driving a Wuling Rongguang mini truck for many years, I believe high fuel consumption is mostly related to driving habits and routine maintenance. For example, stomping on the accelerator when starting or frequently braking and accelerating in urban areas consumes particularly more fuel. As the vehicle ages, component wear has an even greater impact - like when a dirty air filter isn't replaced, restricted airflow forces the engine to burn more fuel to maintain power. Low tire pressure increases rolling resistance like driving on underinflated tires, which also wastes fuel. I regularly check tire pressure with a gauge to maintain recommended levels and give the body a quick wipe-down weekly to reduce air resistance. Neglecting maintenance like allowing spark plugs to accumulate carbon deposits causing poor ignition can make fuel consumption skyrocket. Once when I noticed higher fuel use, replacing the air filter at the repair shop immediately reduced consumption by 10%. I recommend paying attention to these details and developing smooth driving habits - overloading the truck makes things even worse.
