What is the relationship between RPM and gear position?

There is no inherent relationship between gear position and RPM; shifting gears is not an action determined solely by the vehicle's RPM. Below is a partial introduction to the relationship between car gear positions and RPM: 1. The optimal RPM of the engine determines the vehicle's economical speed. Keeping the engine RPM within the most fuel-efficient range of 1800-2200 RPM is ideal. The engine's fuel consumption curve is "U"-shaped, with the most fuel-efficient range being between 1800-2200 RPM, and the most fuel-efficient RPM point being 1800 RPM. 2. The RPM at which a car shifts gears is determined by the driving speed. For example, first gear is used for starting, with a reference speed of 0-15 km/h; second gear is for 15-35 km/h; third gear is for 35-45 km/h; and fourth gear is for 45-60 km/h. 3. Gear shifting should be quick and decisive, avoiding hesitation. The clutch pedal should be pressed down quickly and released slowly to prevent the engine RPM from dropping too low after shifting, which could lead to a mismatch between gear position and speed.

Should the C200L use 95 or 98 octane fuel?

The C200L should use 95 octane gasoline. Higher-end vehicles have stricter requirements for fuel quality.

What is a Service Brake?

The service brake is the foot brake, which is a form of brake control. There are two types of brakes: the parking brake and the service brake. The parking brake is usually the handbrake, while the service brake generally refers to the foot brake. During driving, the service brake (foot brake) is commonly used to slow down or stop the vehicle while moving forward. The parking brake not only keeps the car stationary but can also be used if the service brake fails. Once the vehicle comes to a complete stop, the parking brake should be engaged to prevent the car from rolling forward or backward. After parking, besides using the parking brake, if it's a manual transmission vehicle, it's advisable to leave the gear in first when parking uphill and in reverse when parking downhill.
