When the car makes a loud noise upon accelerating, it is often due to excessive engine oil. Here are some additional details: 1. Excessive engine oil increases the resistance during the engine's instantaneous operation, raising the crankshaft's rotational resistance and reducing the engine's power output. 2. Too much oil can enter the combustion chamber and participate in combustion, leading to oil burning, blue smoke emission, and increased fuel consumption. 3. Using the wrong type of engine oil, such as switching from fully synthetic to mineral oil, can cause issues. Always change oil at reputable shops and use genuine products, as counterfeit or low-quality oil can severely damage the engine. 4. When operating the accelerator pedal, place the right heel on the floor of the driver's compartment as a pivot point, gently press the accelerator with the ball of the foot, and use ankle movements to press or release. Apply force softly and smoothly, ensuring a gentle press and gradual lift.

Where to Stop at the Starting Position for Reverse Parking?

When the corner of the garage appears in the left rearview mirror, gradually straighten the steering wheel while observing the distance between the car body and the garage boundary line, ensuring not to cross the line. Below are related introductions about reverse parking: 1. Technique: Align the mirror and turn right fully. When starting the first reverse parking maneuver, observe the position relationship between the left rearview mirror and the parking line. First, turn the steering wheel half a turn to the right and then start moving. After the left rearview mirror covers the parking line, turn the steering wheel fully to the right; when reversing with the steering wheel turned fully to the right, watch the right rearview mirror. Observe the distance between the car body and the right front corner of the garage, keeping this distance at 30 cm. If it is too narrow, adjust the steering wheel. The standard width of the garage line is 15 cm, so in the rearview mirror, it should appear roughly twice the width of the garage line. 2. Precautions: Generally, start in 1st gear and avoid shifting incorrectly. When controlling the speed, turning the steering wheel as quickly as possible is always better. If there is a conflict between the two, prioritize controlling the speed.
