How to Distinguish Between Semi-Synthetic and Full Synthetic Engine Oil?

The most straightforward method is to check the manufacturer's label on the bottle packaging. Full synthetic oil will be clearly marked. The differences between semi-synthetic and full synthetic engine oils are as follows: 1. Different Composition: Semi-synthetic oil is based on mineral oil, refined through hydrogenation. Synthetic engine oil is derived from ethylene and propylene dispersed from natural gas or crude oil, undergoing polymerization, catalysis, and other complex chemical reactions to form high-molecular lubricants. 2. Different Usage Duration: Full synthetic oil has a wider temperature range and a longer service life. 3. Different Viscosity: For the same oil film requirements, synthetic oil has lower viscosity, while semi-synthetic oil has higher viscosity compared to synthetic oil.

Where is it safe to leave a phone in the car during summer?

You can leave your phone anywhere in the car during summer, but due to high temperatures, the phone's battery may explode. It's important to ensure the temperature inside the car does not exceed 30 degrees. Here are some related points: 1. High-temperature environment: Besides direct sunlight, the environment can also significantly harm the phone. For example, in an open car, the temperature can rise to 60 degrees Celsius under the summer sun, and even reach up to 80 degrees Celsius. 2. Component aging: In such conditions, the phone's components, especially the battery, age faster. If spontaneous combustion or explosion occurs in this hot environment, it can lead to serious property damage.

How to Turn On Front and Rear Fog Lights?

Front and rear fog lights activation method: Press and hold the fog light buttons to turn them on. Fog lights are divided into front and rear types, with front fog lights typically being bright yellow and rear fog lights red. The symbols for rear fog lights differ slightly from front fog lights—the front fog light symbol has downward light beams while the rear fog light symbol features parallel beams, usually located on the vehicle's dashboard console. Fog lights generally refer to automotive fog lights installed at the front and rear of the vehicle. Due to low visibility in foggy conditions, which limits driver visibility, these lights can extend operational distance. Particularly, the strong penetrating power of yellow fog lights enhances visibility for both drivers and surrounding traffic participants, allowing approaching vehicles and pedestrians to detect each other from a greater distance.

Incorrect Throughput of Fuel Tank Ventilation System?

Abnormal throughput in the fuel tank ventilation system is usually caused by a blockage in the activated charcoal canister or the canister purge valve. Below is an explanation of the functions of the fuel tank ventilation system: 1. Noise reduction: During driving, the exhaust gases leave the engine at high pressure, generating significant noise. The exhaust pipe contains a muffler, which helps reduce noise. 2. Emission control: The automotive exhaust system includes a "three-way catalytic converter" device that reduces pollution. This device converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation-reduction reactions, thereby purifying the exhaust and reducing air pollution.
