After maintenance, if the car feels sluggish, it may be because the engine oil has not yet reached the lubrication surfaces of the engine, and the internal components of the engine have not received sufficient lubrication, which is why the lack of power occurs. Here are some related explanations: 1. During maintenance, changing the engine oil is the most common maintenance item. Some car owners report that after changing the engine oil, the car experiences a lack of power during acceleration. This is actually related to the viscosity and quality of the engine oil. 2. Choosing engine oil that matches the car's engine is crucial. If the viscosity of the engine oil is too thin, it will definitely affect the engine's performance, impacting both the car's working condition and its power. At the same time, the quality of the engine oil also needs attention. Poor-quality engine oil can also adversely affect the engine. 3. When changing the engine oil, it's important to pay attention to the amount of oil used. If too much engine oil is added, the excess oil can easily enter the combustion chamber. Over time, this can lead to carbon buildup in the engine. While it may not affect the engine initially, as time passes, the accumulated carbon will become increasingly severe, not only reducing the car's power but also potentially clogging the catalytic converter's pores, leading to increased fuel consumption.

What is the fuel tank capacity of the Encore?

The fuel tank capacity of the Encore is 40 liters, as officially announced. The Encore uses 92-octane gasoline, with a fuel consumption of 5.5-5.6L per 100 kilometers. A full tank can cover a distance of 714-727km. During daily driving, it is necessary to always pay attention to the remaining fuel level. This is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is recommended to refuel when there are only 2 segments left to avoid running out of fuel midway. During the actual refueling process, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is measured from the bottom of the tank to the safety level, and there is additional space from the safety level to the tank opening. This space ensures that the fuel can expand when the temperature rises without overflowing. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

How to Adjust the Time on a Car Dashboard?

The method to adjust the time on a car dashboard is: 1. Press the left button, wait until the time on the trip computer flashes, then press the right SET button; 2. Pressing SET adjusts the time once, while holding down the SET button makes the time digits jump quickly. Adjust the time by coordinating the use of both buttons. The reasons for inaccurate time on the car dashboard are: 1. Changes in the vehicle's usage environment and condition; 2. The crystal oscillator components inside the dashboard are susceptible to voltage fluctuations in the vehicle; 3. Physical interference from the high-voltage magnetic fields of spark plugs affects accuracy. The car dashboard is a device that reflects the working conditions of various vehicle systems. Its maintenance methods include: 1. Soaking a cloth in clean tap water, wringing it out, and wiping the car dashboard; 2. Applying an anti-scratch protective film on the dashboard screen; 3. Spraying cleaner on the dashboard and wiping it off with a soft cloth.

Can I lightly press the brake to slow down in Subject 2?

Subject 2 allows lightly pressing the brake to slow down, but the engine must not stall, and the vehicle must not come to a complete stop during the test. Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. The test items for cars C1 and C2 include reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curve. When passing through school zones or bus stops, it is necessary to slow down to below 30 km/h. In this case, there is no need to press the clutch first; simply lightly press the brake to decelerate. If there is an emergency situation ahead requiring sudden braking, to prevent the car from stalling while ensuring safety, both the brake and clutch should be pressed simultaneously.

How soon can I reapply for a driver's license after cancellation?

There are two scenarios for reapplying after cancellation of a driver's license: 1. If the license was not locked or blacklisted before cancellation and the applicant meets the requirements for initial application or additional driving privileges, they can reapply after the cancellation information is recorded by the vehicle management office; 2. If the license was locked or blacklisted before cancellation—for reasons such as an unresolved 6-month suspension, drunk driving revocation, hit-and-run, or drug use—the applicant cannot reapply for a license within the specified period, and may even face a lifetime ban. A driver's license, also known as a 'driving permit,' is an official document issued by government transportation authorities to individuals who qualify to drive. It is typically a card. To obtain a driver's license, one must meet the minimum age requirement and pass a driving test.
