Because the material of brushed wheel hubs is special, and using paint for repair cannot fundamentally solve the problem. Here is some relevant information about brushed wheel hubs: 1. Repair Methods: If the scratches on a brushed wheel hub are not severe, just minor scrapes, you can use sandpaper to polish them to a gloss similar to the original. If the scratched area is large, you can also use wheel hub-specific stickers, simply applying them directly. For serious scratches, it is recommended to go to a 4S shop or auto repair shop to use a professional brushing machine for better repair. 2. Maintenance Methods: Although scratches on the wheel hub do not significantly affect the safety of the car, they seriously affect its appearance. When there are stubborn stains on the surface of the wheel hub, it is advisable to use professional cleaning agents, which can gently and effectively remove the stains while minimizing damage to the aluminum alloy surface.

As someone in the auto industry, brushed alloy wheels cannot be repaired by painting because their surface features fine brushed textures created by machine grinding for a metallic finish. Applying a layer of paint would completely cover the texture, turning it into a smooth surface and losing the original sharp style of the car. Worse yet, paint has poor adhesion on brushed materials, leading to peeling or bubbling over time, which actually worsens the repair. The correct approach is to take it to a professional shop for re-brushing with specialized machinery or to perform localized grinding to restore the texture. For daily maintenance, avoid scratches from hard objects and keep them clean to extend their lifespan. Remember, wheels are the face of a car—haphazard painting can lower the vehicle's overall class and safety rating. Although the repair cost might be higher, it's a one-time fix that lasts.

What to Do If 92 Octane Gasoline Is Accidentally Filled with 98 Octane?

Filling a car that normally uses 92 octane gasoline with 98 octane is generally not a problem, but long-term mixing of different octane levels should be avoided. If a vehicle is designed for 95 or 98 octane gasoline and is filled with 92 octane, it may cause issues, especially if 92 octane is used continuously over time. This can lead to increased knocking frequency and accelerated engine wear. Different octane levels have varying utilization rates and combustion efficiencies in the engine. The octane rating represents the ratio of the actual gasoline's anti-knock properties to those of standard gasoline, with higher numbers indicating stronger anti-knock performance. Standard gasoline is composed of isooctane and n-heptane, and higher octane numbers are not necessarily better. It's important to choose the appropriate gasoline octane based on the engine's compression ratio.

How to judge the distance between front and rear through the rearview mirror?

Use the following methods to judge the distance of the vehicle behind in the left lane through the rearview mirror: 1. If the body of the rear vehicle has entered the danger zone to the left of the dotted line in the rearview mirror, it indicates that the distance from the rear vehicle is very close, and turning at this time is not allowed. 2. If the left side of the rear vehicle's body is close to the boundary between the safety zone and the danger zone, you should be vigilant, but it is still safe to signal and turn at this time. 3. If the rear vehicle is in the safety zone, located in the center of the rearview mirror, it indicates that the distance from the rear vehicle is 15-20 meters, and you can proceed with the turning operation normally. 4. If the rear vehicle is in the safety zone, located to the right of the center of the rearview mirror, it indicates that the distance from the rear vehicle is relatively large, and you can proceed with the turning operation normally. Here’s how to judge the distance with the right rearview mirror: 1. If the rear vehicle occupies half of the rearview mirror area, and only half of its body is visible, the distance from the rear vehicle is very close. Your vehicle should maintain the current lane and not turn. 2. If the rear vehicle occupies half of the outer rearview mirror area, and the entire vehicle is visible, the distance from the rear vehicle is about 10 meters. You can signal and turn when the speed is slow. 3. If the rear vehicle occupies 1/3 of the outer rearview mirror area, and the entire vehicle is visible, the distance from the rear vehicle is about 15 meters, and you can proceed with the turning operation. 4. If the rear vehicle occupies 1/4 of the outer rearview mirror area, and the entire vehicle is visible, the distance from the rear vehicle is about 24 meters, and you can proceed with the turning operation.

Is it normal to hear gas when opening the fuel tank cap during refueling?

It is normal to hear a small amount of gas escaping when opening the fuel tank cap during refueling. However, if a large amount of gas is released, it may indicate a clogged carbon canister, and you should consider having it inspected at a repair shop. Gasoline is a volatile substance and naturally produces vapor. Under normal circumstances, this vapor is not allowed to be released into the air to prevent pollution, which is why car manufacturers designed the carbon canister. Methods to check the condition of the carbon canister solenoid valve: 1. If gas sprays out when opening the fuel tank cap, it indicates a damaged solenoid valve; 2. If gasoline vapor or dripping oil appears at the carbon canister's atmospheric vent, it indicates a damaged solenoid valve; 3. Symptoms such as weak acceleration, jerking, unstable idle speed (fluctuating up and down), indicate a damaged solenoid valve; 4. If the engine fails to start after shutting off or produces abnormal noises while driving, it indicates a damaged solenoid valve.

What is the reason for the engine yellow light to come on?

The reasons for the engine yellow light to come on are: 1. Sensor issues, including water temperature, intake air temperature, oxygen sensor, etc. When these sensors are damaged, have poor contact, or signal interruption, it will cause the engine fault light to come on; 2. Maintenance issues, vehicles have a certain maintenance cycle. If the owner does not perform maintenance on schedule, combined with poor driving habits, it will increase the burden on the engine operation and cause the fault light to come on; 3. Poor combustion of the mixture, engine spark plug failure, ignition coil failure, fuel pump failure, fuel line blockage, etc. will all cause the engine fault light to come on. The engine components include: the engine block, crankshaft and connecting rod mechanism, valve train and intake and exhaust system, supply system and governor, starting device, cooling system, and lubrication system.
