Car anti-fog spray is generally applied to the inside. Waterproof function of anti-fog spray: Rainwater falling on treated car glass will quickly form small droplets under the action of the protective layer. When the droplets grow to a certain size, they will slide down the glass due to gravity, simultaneously carrying away dust on the glass, effectively cleaning the glass in the process. Anti-freeze function of anti-fog spray: Treated glass has a protective layer, preventing snow or fog water from freezing solidly on the glass in winter. Snow accumulation on the glass can be easily removed, saving the trouble of clearing and waiting time.

How to Determine the Right Gasoline Grade for Your Car?

Here are the detailed methods to check the gasoline grade: 1. Owner's Manual: Refer to your car's owner's manual, which records the recommended gasoline grade for your vehicle. 2. Fuel Tank Label: The fuel tank cap will indicate the fuel grade, specifying which gasoline grade is recommended or optimal. Below is additional information about gasoline: 1. Gasoline Grades: Currently, there are three gasoline grades in China, namely 90, 93, and 97. Gasoline grades are classified by octane rating. 2. Gasoline Selection: If a high-compression engine uses a low-grade gasoline, it can cause a sharp rise in cylinder temperature, incomplete combustion of gasoline, severe engine vibration, resulting in reduced power output, damage to engine components, increased fuel consumption, and poor driving performance. Conversely, if a low-compression engine uses high-grade gasoline, it may lead to delayed combustion, meaning the fuel does not reach its auto-ignition point at the maximum compression ratio, resulting in incomplete combustion.

Why is the Levin particularly fuel-consuming?

The level of fuel consumption is related to the following factors: 1. Driver's driving skills: The level of fuel consumption is related to the driver's driving skills. The same car driven by different drivers will have different fuel consumption. For example, aggressive driving on highways, reckless acceleration, and excessively high RPMs can increase power but also make the car very fuel-consuming. Another example is poor route planning, leading to driving on congested highways with frequent braking. 2. Vehicle maintenance: The level of fuel consumption is related to vehicle maintenance. For instance, low tire pressure can make the car harder to drive and increase fuel consumption. Unnecessary weight, such as carrying rarely used or unused items in the car, can make the vehicle heavier, requiring the engine to produce extra power to move it. Some drivers also enjoy excessive modifications like large body kits, oversized spoilers, or flashy rims, which disrupt the car's balance and increase weight and fuel consumption. Additionally, aging spark plugs or a dirty air filter can also lead to higher fuel consumption.
