In winter, 5W30 engine oil is more suitable. Winter engine oil must meet three key characteristics: low viscosity, low pour point, and good anti-wear performance to provide optimal protection for the engine. Winter temperatures are relatively low, which reduces the fluidity of oil in cold conditions. Some oils may even solidify in environments below -10°C, so winter-grade oil needs to have excellent low-temperature fluidity. When selecting winter engine oil, it's also important to distinguish between oil categories, which include mineral oil, semi-synthetic oil, and full synthetic oil. Most mineral oils are paraffin-based, and wax tends to crystallize at low temperatures, significantly increasing the oil's viscosity.

What is the fuel tank capacity of the Buick Verano in liters?

The fuel tank capacity of the Buick Verano is 44 liters, as officially announced. Owners who have purchased the Buick Verano can also check this information on the vehicle's configuration sheet. The Buick Verano requires 92-octane fuel, with a fuel consumption of 5.8 to 6.3L per 100 kilometers. A full tank can cover a distance of 698 to 759 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

Is it a problem to add a bottle of fuel additive to 10 liters of gasoline?

10 liters of gasoline should not directly mix with a whole bottle of fuel additive. The recommended mixing ratio for fuel additives is 1:1000. A 65ML bottle of fuel additive is designed for 50-65 liters of gasoline. For 10 liters of gasoline, approximately 10-15ML (about 1/4 bottle) of fuel additive should be added. Excessive imbalance in the mixing ratio may cause engine knocking. Precautions for adding fuel additives: Maintain the proper ratio, with fuel to additive at 1000:1; Add in batches: first pour a bottle of additive into the fuel tank, then add the appropriate proportion of gasoline. Subsequently, add half a bottle of additive for every 25 liters of gasoline refilled; Avoid excessive frequency of use. Overuse of fuel additives can easily lead to oil contamination and may adversely affect the fuel tank, engine, and the vehicle itself. Hazards of excessive fuel additive usage: Fuel additives are auxiliary products. Long-term excessive use can increase carbon deposits in the combustion chamber, leading to engine knocking and detonation. Therefore, it's important to pay attention to the quality of the fuel additive when using it.

What are the reasons why the Sylphy's one-button start cannot detect the key?

Sylphy's one-button start cannot detect the key due to reasons such as insufficient key battery, key malfunction, or electromagnetic interference. Insufficient key battery: If the one-button start cannot detect the key, the first thing to check is whether the car key still has power. You can try replacing the key's battery and then attempt the one-button start to see if it returns to normal. If it doesn't, it could also be due to poor battery contact, in which case the car key may need to be repaired. Key malfunction: You can try using the car's spare key to check if the first key is malfunctioning. If the spare key works, it indicates that the first key is faulty. If the spare key also doesn't work, you need to take the car to a repair shop for inspection. Electromagnetic interference: You need to analyze whether there are other sources of electromagnetic or signal interference. Sometimes, placing a phone and the car key together can cause interference, or the car's dashcam might also interfere with the car key. You can place the key in a separate location and try starting the car again. If it still doesn't start, you need to check the transmitter and receiver.

Reasons for the Persistent Tire Pressure Warning Light in the 2020 Honda XR-V

The persistent tire pressure warning light in the 2020 Honda XR-V indicates an abnormality in the tires. The method to reset the tire pressure light for the 2020 XR-V is as follows: first, restore the tire pressure to normal levels before resetting, start the vehicle, and then press and hold the tire pressure SET button on the center console until the tire pressure data refreshes. Tire pressure monitoring light: The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top and four small spikes at the bottom, containing an exclamation mark inside. The illumination of the tire pressure monitoring light indicates abnormal tire pressure. Abnormal tire pressure generally has the following three causes: Abnormal tire pressure: Typically, an alarm is triggered when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, it can also cause the tire pressure warning light to turn on. For sensor damage issues, the only solution is to replace it with a new component.

What Are the Common Problems with Cars?

Common problems with cars include: 1. Engine failure to start; 2. Punctured or burst tires; 3. Brake failure; 4. Abnormal noises from the body or engine. Solutions to these common car problems are: 1. Use jumper cables or an emergency power source to charge the battery; 2. Inspect and repair the electrical circuits and fuel lines; 3. Regularly check tire pressure and wear; 4. Maintain the brake system; 5. Periodically inspect the wear level of brake discs and pads; 6. Avoid prolonged braking and use lower gears when going downhill to prevent overheating of brake pads; 7. Inspect and repair the generator, water pump, and power steering pump.

Why Is There Water Under the Car Seat?

Here are the reasons for water under the car seat: 1. Not closing the windows tightly on rainy days: After getting out of the car, failing to ensure that the windows are tightly closed may allow rainwater to seep into various parts of the car through the gaps. Over time, water may drip under the driver's compartment. 2. Issues with drainage outlets: After ruling out human factors, if water still drips under the driver's compartment, the car's drainage outlets should be checked. There are four drainage outlets in a car—the front two are for sunroof drainage, and the rear two are for draining water flowing on the car.
