Why Does the New Nissan Sylphy Have High Fuel Consumption?
2 Answers
Automobile fuel consumption is directly related to five major factors: driving habits, the vehicle itself, road conditions, natural wind, and environmental temperature. The specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle in advance when approaching a red light can increase fuel consumption. The vehicle itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements typically produce more power, requiring more gasoline to burn and perform work. Heavier vehicles also have higher fuel consumption because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance, leading to higher fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance, thereby increasing fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during cold starts, requiring more gasoline to burn, which increases fuel consumption. Additionally, at low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, which also increases fuel consumption. Here are five tips to help reduce fuel consumption while driving: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Pressing the accelerator hard can multiply fuel consumption. Gentle acceleration and braking, early braking: While driving, press the accelerator lightly to avoid sudden increases in engine RPM and prevent the car from shaking during operation, which helps save fuel. By anticipating road conditions and applying slow, even acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value, fuel consumption increases by 1%. Regular vehicle maintenance or inspections: Timely oil changes can reduce carbon buildup; regularly check and replace the air filter if dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per mileage recommendations. Keep windows closed while driving. Driving with windows open increases wind resistance, which in turn increases the car's resistance, requiring more power and thus increasing fuel consumption.
I just bought a new Nissan Sylphy two months ago, and the fuel consumption has been consistently high. After chatting with fellow car owners, I found that the main reason is the break-in period for new cars. Components like the engine and transmission need a few thousand kilometers to run smoothly, so temporarily higher fuel consumption is normal. Another issue is my driving habits. Driving in the city involves frequent stops and starts, with many instances of sudden acceleration and braking, which consumes more fuel each time. I also checked the tire pressure—it was slightly low when I picked up the car from the dealership. After inflating it to the standard value, the fuel consumption decreased a bit. Regarding load, the trunk is always packed with stuff, which adds unnecessary weight. The AC is used too frequently in summer, forcing the engine to work harder. It's recommended to drive smoothly during the break-in period, regularly check tire pressure, avoid overloading, and reassess fuel consumption after the break-in period is over.
