Is Gasoline Additive Useful?

Fuel additive, commonly referred to as fuel booster, is not entirely useless, but its effectiveness is far less than what is advertised. In most cases, using fuel additives serves more as a psychological comfort. Below is relevant information about fuel additives: Fuel additives were developed to remove carbon deposits. There are numerous brands of fuel boosters on the market, with various types available, including cleaning-type fuel boosters, performance-enhancing fuel boosters, maintenance-type fuel boosters, and vehicle-specific fuel boosters. Here are introductions to several types of fuel additives: 1. Cleaning-type fuel booster. For fuel-injected vehicles, the key component of fuel boosters is polyetheramine (PEA). PEA is highly resistant to carbonization under high temperatures and has strong cleaning capabilities, which can partially remove surface carbon deposits from areas such as pistons, cylinder walls, valve ports, and fuel injectors. However, long-term accumulated carbon deposits may not be completely removed. Since fuel boosters are added to the fuel tank, they theoretically have a certain cleaning effect on areas where the fuel passes through. Areas not in contact with the fuel, such as the intake manifold and throttle valve, will not benefit from the cleaning effect. 2. Performance-enhancing fuel booster. The claim of performance enhancement is largely exaggerated by merchants. Its primary function is to suppress engine knock, which causes the engine to automatically delay ignition, leading to reduced power and increased fuel consumption. Adding such fuel boosters increases the octane rating, suppresses knock, and allows the engine to ignite normally, restoring its power rather than enhancing it. This type of fuel additive is designed for low-quality gasoline. 3. Maintenance-type fuel booster. Similar to dietary supplements, no matter how good they are, they cannot cure diseases. As soon as the engine starts running, carbon deposits will inevitably form. Moreover, maintenance-type fuel boosters are low-cost but high-priced, causing many car owners to spend money unnecessarily with uncertain results. They are not as effective as performing an internal engine carbon cleaning or using an IV drip method every 40,000 kilometers. 4. Vehicle-specific fuel additives. These are fuel boosters specifically developed for certain vehicle models. For example, Honda recommends adding its dedicated fuel cleaner regularly during maintenance at 4S shops for its new models. This is because Honda engines generally use the VTEC system, which stands for Variable Valve Timing and Lift Electronic Control. This system provides good power, high torque, and fuel efficiency, but it has a significant weakness: high sensitivity to carbon deposits. Due to the presence of low-speed and high-speed camshafts, the intake valve opening is relatively small at low speeds, meaning the intake cross-sectional area is small. If carbon deposits contaminate this area, they can significantly affect airflow. The vehicle's ECU may misjudge the situation, leading to unstable fuel injection regulation. Given this characteristic of Honda engines, the company recommends that car owners add Honda's dedicated fuel additive twice a year.

Where is the windshield washer fluid reservoir located in a Buick?

In the Buick Verano, the windshield washer fluid reservoir is located on the left side of the engine compartment. It is a small blue-capped container marked with a windshield washer symbol. Below are the specific functions of automotive windshield washer fluid: 1. Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, thereby providing cleaning and stain removal effects. 2. Antifreeze performance: It significantly lowers the freezing point of the liquid, preventing freezing and quickly dissolving frost. 3. Anti-fog performance: It forms a single-molecule protective layer on the glass surface. This protective layer prevents the formation of fog droplets, ensuring clear visibility through the windshield. 4. Anti-static performance: After cleaning with windshield washer fluid, substances adhering to the glass surface can eliminate static charges on the glass, providing anti-static properties.

What is the maintenance cycle for various car components?

Gasoline filter replacement cycle is approximately 2000-3000 kilometers. Here are the details: 1. "Three Filters" replacement: The replacement cycle for dirt removal and cleaning accessories should follow the car manufacturer's manual. The maintenance cycle for the air filter is 6000-8000 kilometers; the oil filter maintenance cycle can be synchronized with oil changes; the gasoline filter replacement cycle is 2000-3000 kilometers. 2. Engine components: The engine is a crucial part for the normal operation of the car. Regularly replacing engine-related accessories plays a significant role in maintaining the vehicle's normal use. The replacement cycle for the engine timing belt is 50,000-60,000 kilometers; the drive V-belt replacement cycle is 40,000 kilometers; the gasoline hose maintenance cycle is approximately 80,000 kilometers. 3. Antifreeze: The antifreeze has a validity period of 1-2 years, and the replacement cycle is every two years of vehicle operation. Antifreeze tends to expire in summer, and particles may precipitate after one year of use, at which point the antifreeze should be replaced. When replacing car antifreeze, it is essential to use the same brand and avoid mixing. Choose an antifreeze brand suitable for all seasons.

Why is the car air conditioning not cooling when the pressure is normal?

The reasons why the car air conditioning is not cooling when the pressure is normal are as follows: 1. Lack of refrigerant: Car air conditioners generally need to be refilled with refrigerant every 2~3 years, and some cars even require it annually. Even if the air conditioning system is tightly sealed, it cannot prevent the refrigerant from escaping, as there might be minor leaks in the air conditioning pipes or condenser. 2. Damage to the air conditioning flap: Although it is relatively rare, failures of the air conditioning flap motor are not uncommon. The flap motor is usually located under the dashboard and serves as the main switch for the air conditioning vents. If it is damaged, it means the switch is broken. Even if the air conditioning can cool the air, the cold air can only escape through gaps. 3. Dirty condenser: It is common to find air conditioning failures during summer. When testing the air conditioning system, no issues are found, and both high and low pressures are basically normal. When taking the car to a 4S shop for repair, the owner is often advised to clean the radiator. The main purpose of cleaning the radiator and condenser is to improve heat dissipation. In spring, willow catkins can stick to the condenser, leading to excessively high engine temperatures or air conditioning failure.

Can Someone Else Take Points Off My Driver's License?

Here is the introduction to whether someone else can take points off your driver's license: 1. Currently, points on a driver's license cannot be transferred to someone else. The person who commits the violation must have their own points deducted. Having someone else take the points is illegal. 2. The deduction of points from a driver's license is recorded. If you sell your points to someone else, the system will automatically assume that the license holder is the person responsible for the violation. 3. If the person who buys the points commits other illegal acts, such as hit-and-run, in addition to the traffic violation, the person who sold the points may bear corresponding legal liabilities. Additional information: Here is why you should not help others remove points from their license: 1. It is illegal. 2. There are restrictions on removing points from a driver's license. 3. If the driver's violation involves a traffic accident, they may bear corresponding legal liabilities. 4. Your available points will decrease. If you commit a violation yourself and don't have enough remaining points, you will have to retake the written test (Subject 1).

Why does the engine sound change after the vehicle wades through water?

It may be related to water entering the bearings of the engine belt and wheel bearings. The following is a related introduction about vehicle wading: 1. Introduction to vehicle wading: As the name suggests, vehicle wading refers to driving in low-lying areas or on roads with accumulated water, passing through water. This generally occurs in rainy weather, where inadequate drainage equipment leads to water accumulation in low-lying road sections. 2. Precautions for vehicle wading: Before wading, observe the road conditions carefully; maintain stable power while in the water; after wading, check the electrical system. If the car stalls in the water, the main reason is usually water entering the exhaust pipe, and in some cases, there may also be electrical damage. Once the car stalls, do not attempt to restart it, as this may cause water to enter the intake manifold and damage the valves, potentially leading to severe engine damage. Instead, the vehicle should be towed to a 4S shop immediately for professional handling.
