Shift to S gear in the following situations: 1. Overtaking: S gear maintains lower gears longer and increases fuel supply, allowing faster acceleration during overtaking; 2. Uphill driving: Using S gear provides more power and makes climbing easier; 3. Long downhill descents: On steep slopes, S gear enables engine braking to prevent overheating of wheel brakes and reduced braking efficiency; 4. Traffic congestion: S gear effectively reduces shift frequency, prevents transmission overheating and wear, and allows quick starts for better positioning; 5. Carbon deposit removal: Engaging S gear temporarily increases engine load and raises internal temperature, helping remove carbon deposits, which can reduce fuel consumption and extend engine lifespan.

When driving an automatic transmission car, I usually switch to the S (Sport) mode when I need a temporary boost in power. For example, when overtaking on the highway and feeling a lack of power, I shift to S mode to keep the engine at higher RPMs for quicker acceleration to pass. I also frequently use it when climbing steep hills or towing heavy loads uphill, as it helps the transmission delay shifting, making it easier to ascend without rolling back. Additionally, on snowy or slippery roads, I switch to S mode to reduce frequent gear changes and prevent tire slippage, allowing for better vehicle control. However, remember not to use it for extended periods, as it can significantly increase fuel consumption and cost more in gas. Overall, S mode is like a little assistant—only used in specific scenarios. For everyday city driving, D (Drive) mode is more fuel-efficient, quieter, and provides a more comfortable ride.

I often use the S mode when driving in mountainous areas or on winding roads because it keeps the engine at higher RPMs, making the throttle response more sensitive and acceleration smoother when cornering, so I don't have to worry about a lack of power. Especially when overtaking large trucks or quickly changing lanes, switching to S mode raises the engine RPM, and with a press of the accelerator, the car surges forward, making it much safer. It also performs well when towing a small boat or camping equipment uphill, but be aware that prolonged use can increase fuel consumption and accelerate engine wear, so I always switch back to D mode after use to maintain economical driving. Additionally, switching to S mode on icy winter roads can help prevent slipping, but it's important to use the brakes properly and not drive too fast.

What are the differences between OEM brake pads and aftermarket brake pads?

OEM brake pads and aftermarket brake pads mainly have the following differences: Material comparison: OEM products contain more ceramic and graphite than metal. Ceramic and graphite are more wear-resistant than metal, resulting in a longer service life. Aftermarket products clearly contain more metal than ceramic and graphite, with poorer wear resistance compared to OEM products, significantly shortening their service life. Thickness comparison: OEM products are strictly manufactured according to standards, with both thickness and materials meeting requirements. To save costs, aftermarket products reduce the thickness, greatly shortening their service life. Factory serial number: OEM products have a factory serial number printed on the surface, just like a person's ID card, ensuring quality. Aftermarket products lack a factory serial number, making their quality unverifiable.

What Causes a Diesel Engine to Not Exceed 2000 RPM and Experience Idling?

Diesel engine not exceeding 2000 RPM and experiencing idling can be caused by insufficient fuel pump pressure or exhaust issues. Details are as follows: Insufficient Fuel Pump Pressure: When the fuel pump pressure is inadequate, the fuel injection volume is insufficient, preventing the engine from increasing its RPM. Exhaust Issues: Poor exhaust flow reduces the efficiency of the engine's intake and exhaust system, hindering RPM increase. Causes of Idling: When the tangential force on the locomotive's driving wheels exceeds the adhesion force between the wheels and rails, adhesion is disrupted. This results in relative sliding between the wheels and rails at the contact point. Under the driving torque, the wheels rotate rapidly around the axle, leading to idling.

Can the wheel hub damage be claimed under vehicle damage insurance?

The insurance company will compensate for the damaged wheel hub. If the loss caused by a traffic accident includes damage to the tires and wheel hubs, the insurance company will provide compensation. Compensation for tire blowouts: The insurance company will not compensate for the loss of components such as rims and wheel hubs because tires are consumables and are not covered by the insurance policy. The car owner needs to pay for the repair or replacement of the tires themselves. However, for other losses caused by a tire blowout that leads to a traffic accident, as long as the car owner has purchased the corresponding car insurance, the insurance company must compensate. Avoiding insurance fraud: 58 Auto strongly advises against fabricating scenes to commit insurance fraud, as it harms the interests of the insurance company and can also leave a negative credit mark on oneself, making it difficult to obtain car insurance from any company in the future.
