Which has higher fuel consumption: city driving or highway driving?

[JordanLynn]

City driving consumes more fuel. On city roads, cars often idle, while on highways, cars do not idle. During car design, there is an optimal speed for fuel efficiency, at which the car's fuel consumption is the lowest. On city roads, the car's speed is often much lower than this optimal speed. When driving in daily life, pay attention to the following: Choose high-quality fuel and regularly clean carbon deposits. Poor-quality gasoline can increase carbon deposits in the engine, roughen the intake pipe, affect air intake efficiency, and increase fuel consumption. Regularly check tire wear and tire pressure. Low tire pressure increases friction between the tires and the road, leading to greater resistance and higher fuel consumption. Also, frequently inspect tire wear. Severe wear can cause slipping, resulting in increased fuel consumption. Daily driving habits also impact fuel consumption. Therefore, reasonable vehicle use is not just about following the owner's manual; developing good driving habits is equally crucial.
