The original engine oil for the Buick Excelle 1.4T is Mobil 1 5W-30 full synthetic oil; the Buick Excelle 1.5L uses the factory 5W-30 semi-synthetic oil. Below is the relevant introduction about engine oil: 1. Comparison between 5W30 and 0W20: 5W30 and 0W20 have different high and low-temperature performance. 0W20 has better low-temperature fluidity and can be used in lower environmental temperatures; while 5W30 has better high-temperature protection performance, with higher viscosity. Although it increases fuel consumption, considering the Excelle model, 5W30 is more suitable for its engine requirements. 2. Engine oil brands: For the choice of engine oil brands, if long-lasting oil is needed, Mobil oil can be used; if the oil needs strong cleaning ability, Shell oil is recommended; if the oil needs strong oil film toughness, Castrol is suggested. For turbocharged engines, which are prone to carbon deposits during high-speed operation, Shell oil with strong cleaning ability can be used.

Why hasn't the ETC fee been deducted?

The reason why the ETC fee hasn't been deducted might be due to the ETC debit card, which records the fees first and deducts them uniformly at the end of the month on the settlement day. If the fee hasn't been deducted by the end of the month, you can call the bank or ETC customer service to inquire. After all, ETC is linked to a bank card and will appear on the credit report, so it is recommended that car owners proactively check. Below is an introduction to the bank cards bound to ETC: 1. Credit Card: Car owners don't need to top up the ETC card because it is bound to a credit card, which operates on a 'pass first, pay later' basis. If there isn't enough savings in the credit card, the system will automatically deduct from the credit limit. 2. Stored Value Card: The main function of a stored value card is basic transfers and it doesn't have an overdraft feature. Just like a mobile phone's SIM card, you can only make calls if there is money in it. Similarly, a stored value card can only be used for passage if there is money in the card. Car owners need to top up the stored value card in time to avoid delays on the highway and affecting their mood.

Will a scooter get damaged if left in the rain overnight?

Scooters are designed with rainproof features, so being exposed to rain for one night generally won't cause issues. However, frequent exposure to rain is not recommended. Although motorcycles lack enclosed spaces and have a certain degree of water resistance, prolonged exposure to rainwater is not advisable. Many switches and critical components remain exposed. To prevent failures or malfunctions due to sealing issues or long-term corrosion, it's best to park the vehicle in a covered area or use a protective cover to extend its lifespan. Motorcycles are characterized by being powered by gasoline engines. They are lightweight and agile two- or three-wheeled vehicles widely used for patrols, passenger transport, and cargo delivery, and can also serve as sports equipment. A motorcycle consists of five main components: the engine, transmission system, running gear, braking system, and electrical equipment. For motorcycle maintenance, it's important to regularly change the engine oil. Over time, engine oil deteriorates, and metal particles from component wear and carbon deposits from combustion can contaminate the oil. Degraded oil loses its lubricating properties, accelerating engine wear. Oil changes should be performed when the engine is warm, as the dirty oil in the crankcase flows more easily and drains better from the oil ports. It's advisable to kick the starter pedal several times to fully drain the residual oil. If necessary, fresh oil or diesel can be added for flushing.

Can I get maintenance done at a 4S store other than where I bought the car?

You can get maintenance done at a 4S store other than where you bought the car. You can choose another 4S store of the same vehicle brand for maintenance, as 4S stores offer nationwide warranty services. Just bring your vehicle license and maintenance manual when getting maintenance done. Labor costs are generally similar within the same city. Additionally, the first maintenance is free within the specified time period, and you'll only need to pay if it exceeds the first maintenance requirement. Below is an introduction to new car maintenance: 1. Change engine oil and clean the three filters: Change the engine oil and clean the three filters, which are the oil filter, fuel filter, and air filter. 2. Check the car's coolant: Ensure the coolant level is within the normal range. 3. Check the car's brake system: Inspect the car's brake system and the fluid level of the clutch. 4. Check the power steering fluid level: Verify the power steering fluid level is normal and check for any oil leaks at the pipe connections. 5. Check for component aging: Examine the generator, air conditioning, water pump, and belts for aging and tension. 6. Check tire pressure and wear: Inspect tire pressure and wear condition, inflate the tires if needed, or rotate them if there is significant wear.

Should You Shift Gear or Release the Handbrake First When Driving?

Either shifting gear first or releasing the handbrake first is acceptable. Below is relevant information regarding gear shifting and handbrake usage for automatic and manual transmission vehicles: 1. For automatic transmission vehicles, after starting the engine, you can first release the handbrake but must keep the brake pedal depressed, as automatic cars can only shift into D gear when the brake pedal is pressed. Alternatively, you can keep the handbrake engaged, press the brake pedal, shift into D gear, continue holding the brake, and then release the handbrake before letting go of the brake. 2. For manual transmission vehicles, after starting the engine, you can first release the handbrake while pressing the brake pedal, then shift gear and start moving. Another option is to shift gear first, and once the car has a tendency to move forward, you can release the handbrake. Whether you release the handbrake first or later has no impact. If you prefer not to use the handbrake, you can simply press the brake pedal. 3. When driving a manual transmission car, it's important to avoid prolonged attempts to start the car with the clutch in a semi-engaged state, as this accelerates the wear of both the clutch plate and the release bearing. During startup, the duration of the semi-engaged state should be controlled carefully. The clutch plate is a wear-prone component, and improper usage habits can significantly reduce its service life.

How many points are deducted for the front of the car crossing the line in Subject 2?

Crossing the line means the vehicle body goes out of the designated line. In the Subject 2 driving test, if the vehicle body crosses the line, 100 points will be deducted, resulting in a failed test. In addition to the vehicle body crossing the line, other actions that will deduct 100 points include failing to park properly in reverse parking, stopping midway, not following the prescribed route or sequence, and exceeding the allotted time. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed if the following conditions are met: ① For applicants of large buses, tractors, city buses, medium buses, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. If a candidate fails the Subject 2 test, they are allowed one retake on the spot. If they do not take the retake or fail the retake, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of test attempts for Subject 2 and Subject 3 road driving skills cannot exceed five. If the fifth attempt is still unsuccessful, the scores of other previously passed subjects will be invalidated.
