"How many oils does a car use" refers to the fuel consumption per 100 kilometers, which means the amount of fuel (in liters) required for a car to travel 100 kilometers. Below is some information about car fuel consumption: 1. Calculation method: (Amount spent on fuel ÷ Fuel price) ÷ Kilometers driven × 100 = Fuel consumption (liters). The number of liters of fuel consumed for a car to travel 100 kilometers is referred to as 'how many oils'. For example: If a car consumes a total of 19 liters of fuel to travel 200 kilometers, it can be said that the car's fuel consumption per 100 kilometers is 9.5 liters. 2. Practical significance: Fuel consumption per 100 kilometers refers to the fuel consumption of a vehicle traveling a certain speed on the road for 100 kilometers. It is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is a value measured by the manufacturer in an objective environment using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then the theoretical experimental fuel consumption data per 100 kilometers of the vehicle model is calculated by driving at a specified speed.

When we talk about a car's 'fuel consumption in liters', it refers to how many liters of gasoline the car burns per 100 kilometers. For example, my car consumes about 9 liters per 100 km in city driving, meaning it burns 9 liters of fuel for every 100 kilometers traveled. Actually, this number depends on how you drive. In stop-and-go city traffic, where the engine often operates inefficiently, fuel consumption can easily exceed 10 liters per 100 km. On the highway at a steady speed, it might drop to around 7 liters. Additionally, underinflated tires increase rolling resistance, and a fully loaded trunk also consumes more fuel. So, to save on fuel costs, it's important to develop good driving habits—avoid sudden acceleration and hard braking. The official fuel consumption figures listed on the yellow sticker of new cars are measured under laboratory conditions, and real-world driving will typically be higher, so keep that in mind when buying a car.

Is it necessary to shift to N gear when having Auto Hold?

Cars equipped with the Auto Hold function do not require shifting to N gear during temporary stops. Auto Hold is essentially an automatic braking feature. When waiting at traffic lights, there is no need to engage the handbrake or electronic parking brake, and consequently, there's no need to change gears. However, in situations of severe traffic congestion where the vehicle remains stationary for extended periods, it is advisable to deactivate the Auto Hold function and switch to manual control by shifting to neutral (N gear). This practice helps protect the transmission and engine, thereby extending their service life. The English term for Auto Hold is 'AutoHold,' and its button is typically marked with a capital letter 'A' or the full English spelling. It relies on an intelligent braking system to function.

Matching RPM and Gears in Manual Transmission?

Manual transmission vehicles require proper gear-speed synchronization as follows: 1st gear at 15 km/h; 2nd gear at 25 km/h; 3rd gear at 35 km/h; 4th gear at 55 km/h; 5th gear at 65 km/h or above. Manual transmission, also called manual gearbox, represents a fundamental type of automotive transmission system. Its primary function is to alter the gear ratio (also known as the torque ratio) by utilizing larger-diameter low-gear wheels based on the lever principle's torque mechanism, thereby amplifying engine torque to initiate vehicle movement. A manual transmission consists of three core components: the gear mechanism, transmission housing, and shift linkage assembly.
