Fuel additive can be added after refueling, but the mixture may not be uniform enough in this case. It is recommended to add the fuel additive before refueling at the gas station, following the recommended ratio by pouring the fuel additive into the fuel tank first and then refueling. This way, the added fuel additive will quickly dissolve thoroughly under the impact and vortex stirring of the fuel, ensuring a more uniform mixture of the fuel additive and fuel. Functions of Fuel Additive: The role of fuel additive is to address the carbon deposit issues in the fuel system of fuel-injected vehicles, quickly restore the engine's optimal working condition, and compensate for certain deficiencies in gasoline properties. It also imparts new superior characteristics to gasoline, such as improving atomization, reducing wear, protecting the engine, and lowering emissions. Precautions for Adding Fuel Additive: Currently, the common fuel tank capacity for small family cars on the market is 35-45L, for mid-size cars it's about 55-75L, and for large or luxury cars, it's around 75-100L. The standard specification for fuel additive is usually 60ML, with 60ML typically being suitable for 30-60L of gasoline. Therefore, a common family car usually requires 1-2 bottles of fuel additive per tank of fuel, but the exact amount should be determined based on the specific conditions of the car.

Can Car Insurance Stickers Be Omitted?

Compulsory insurance stickers can be omitted, but compulsory traffic insurance is required. Below is a partial introduction to car insurance: 1. Components: Car insurance generally consists of two parts: basic insurance and additional insurance. Basic insurance is further divided into vehicle damage insurance and third-party liability insurance. 2. Coverage: Vehicle damage insurance covers losses to your own vehicle; third-party liability insurance covers targets outside your own vehicle, such as people hit, public property, and other vehicles; passenger liability insurance covers personal and property losses within your own vehicle; theft insurance covers compensation when your vehicle is stolen; no-deductible coverage ensures 100% compensation in case of an accident. If no-deductible coverage is not purchased, you are responsible for 30% of the deductible in each accident.

What is the appropriate charging current for a car battery?

For a 12V 20Ah battery, the normal charging current ranges from 1.5A to 2.5A. A 24Ah battery charged with 1.5A current will be fully charged within 16 hours. Below is relevant information about car batteries: 1. Battery CCA parameter: Among the performance parameters of a car battery, there is a CCA parameter, which stands for the battery's maximum discharge current value. 2. Meaning of starting voltage: Starting voltage refers to the instant when ignition occurs, the voltage will momentarily drop to a certain point, and the lowest value it drops to is the starting voltage, typically between 7.5V and 9.5V. If the starting voltage frequently falls below 7.5V, it may indicate severe battery discharge or aging.

What does the second car maintenance include?

Specific items for the second car maintenance include: 1. Engine inspection: After performing the 'three cleans and three filters' on the engine, ensure that the engine starts easily, runs smoothly, meets exhaust emission standards, and shows no abnormal noises, water leakage, oil leakage, electrical leakage, or air leakage. 2. Steering inspection: Check for any inflexibility in steering and observe whether there is any wobbling or deviation during operation. 3. Clutch inspection: Ensure there are no abnormal noises, the operation is smooth, the separation is complete, and there is no hydraulic oil leakage. 4. Transmission, drive, and front half-shaft inspection: Check for good lubrication, reliable connections, smooth gear shifting, and no oil leakage. 5. Brake pedal and service brake inspection: The requirements are good braking performance, no deviation or oil leakage. 6. Other areas for incidental inspection include: Signal lights, dashboard lights, buttons, engine, etc., to ensure all are functioning normally. 7. Lubrication: Apply lubricant to all necessary parts of the vehicle. 8. Maintenance: Perform a full vehicle wash and maintenance.

How long does it take to fully charge a 12V battery?

A 12V battery typically takes 8-10 hours to charge when completely depleted. It is necessary to use a dedicated charger to avoid affecting the battery's normal usage. Charging should be time-limited and should not exceed 12 hours, as overcharging can cause severe water loss in the battery, thereby affecting its lifespan. Related information: 1. Reserve power before charging: Generally, the battery should retain at least 20% of its power. The chemical conversion efficiency during charging is about 50%, so charging a fully depleted battery requires adding 150% X 80% of its capacity. 2. Optimal charging current for the battery: It should be 10% of the battery's capacity. The charging time required is 150% X 80%/10% = 12 hours, plus an additional hour or so for segmented charging to increase the duration.

What to Do if It Rains After Car Tinting?

Rain after car tinting has no effect because the film is applied to the inside of the car. As long as the windows are not opened, the rain cannot reach the film. Additionally, after the car is tinted, the windows should not be opened for 48 hours. Pay attention to the following precautions after tinting: 1. Do not open side windows: Avoid opening the side windows for 48 hours after tinting. 2. Cleaning tips: Do not use solutions containing alcohol or ammonia to clean the tinted film; cleaning can be done 2-3 weeks after tinting. Use a lint-free towel or other soft items to wipe gently. Avoid using hard-bristle brushes or other hard objects to prevent scratching the film. 3. Bubbles: If bubbles appear, they must be addressed at the tinting shop within 24 hours. Do not attempt to fix them yourself. 4. Adhesive labels: Do not place adhesive labels directly on the tinted film. 5. Fogging: After tinting, there may be fogging between the glass layers, which is normal. The fogging will disappear within 2-3 weeks.

Can You Still Drive When the Coolant Warning Light Comes On?

Here are the reasons for the coolant warning: 1. Overheating: If the coolant warning is caused by engine overheating, it's best to pull over, keep the engine idling, open the hood, and let it cool down until the temperature warning light goes off. 2. Low Coolant Level: If the issue is due to low coolant level and you don't have coolant available for immediate refill, you can add an appropriate amount of purified water, preferably soft water (distilled water). Do not use hard water like tap water, and avoid adding too much as it may alter the coolant's boiling point.
