60 mph in 4th or 5th gear?

Using 5th gear is better because it is more fuel-efficient than 4th gear when driving at 60 km/h. At 60 km/h, the engine speed in 4th gear is around 2000 RPM, while in 5th gear, it is around 1500 RPM. Due to the higher gear ratio in 4th gear, the engine output torque is lower compared to driving in 5th gear. Here are some additional gear-shifting tips: Shift at the right time: Change gears according to the speed of the car. Downshift based on actual conditions: Sometimes while driving, you may notice the car shaking slightly, indicating that the engine is operating under low-speed, high-load conditions. In such cases, immediately downshift by one or two gears. Coordinate the clutch and throttle properly: When shifting gears, ensure the clutch and throttle are well-coordinated. Press the clutch pedal fully, then release the throttle pedal, and quickly shift to the appropriate gear. After shifting, release your hand immediately and avoid keeping it on the gear lever (commonly known as the gear stick) for too long, as this can easily damage the gear lever.

Having driven in the city for decades, I believe the choice of gear at 60 km/h mainly depends on the situation. If you're cruising at a constant speed on a flat road, fifth gear is more appropriate—it keeps the engine RPM lower, improves fuel efficiency, and makes for a quieter, smoother ride. However, when climbing a hill or needing to overtake, shifting to fourth gear provides more torque, delivering stronger power and quicker response. Modern cars are generally designed with fifth gear optimized for highway cruising, so I usually stick to fifth gear at 60 km/h on highways or national roads—it's fuel-efficient and eco-friendly. Some older models or smaller-displacement engines may require adjusting based on engine sound; if the tachometer shows below 2,000 RPM, it might struggle a bit, so try shifting to fourth gear. The general principle is to prioritize fifth gear for driving efficiency and engine protection, but staying flexible based on specific conditions never hurts.

What does the driving license stake test mean?

Driving license stake test is one of the compulsory subjects in the driving test subject 2, which mainly examines the driver's spatial perception when moving the vehicle. The stake test requires the driver to find appropriate reference points according to their height, make repeated adjustments to ensure the vehicle body is within the appropriate distance, slowly reverse the car, and then judge whether the car body is parallel to the garage line. Once parallel, immediately straighten the steering wheel and continue to reverse slowly. The subject 2 test includes: reversing into the garage for small cars, small automatic transmission cars, small automatic transmission passenger cars for the disabled and low-speed trucks, fixed-point parking and starting on the slope, side parking, curve driving, and right-angle turning.

Are Turbocharged Engines More Prone to Burning Oil?

Turbocharged engines are more prone to burning oil compared to naturally aspirated engines. Here are the relevant details: Reasons why turbocharged engines are more prone to burning oil: Many engines use aluminum alloy cylinder blocks and other components. Since all metals expand with heat and contract with cold, during turbo operation, the gap between the engine cylinder and piston will shrink due to the rapid rise in temperature. Therefore, turbocharged engines are designed with a wider initial gap between the cylinder and piston compared to naturally aspirated engines to prevent component damage from thermal expansion. As a result, when the engine starts, under the same oil viscosity conditions, turbocharged engines allow more oil vapor to enter the combustion chamber than naturally aspirated engines, leading to oil burning.

How Long Does It Take for Car Paint to Fade in the Sun?

There is no fixed time; it depends on the quality of the car paint, and it is best not to expose it to prolonged sunlight. Below is relevant information: 1. Overview: Car paint (English name: Car-paint) has undergone three major leaps in history: alkyd (enamel) paint in the 1920s, acrylic (enamel) paint in the 1960s, and clear coat (urethane) in the 1980s. 2. Other: Car paint is a protective film sprayed onto vehicles, a type of coating that makes the car body less susceptible to corrosion. Different car paints have different effects, and the quality of the paint itself, along with the technology and a good painting environment, is crucial.

What does 'excellent condition' mean for a car?

A vehicle that has been driven for two years with 60,000 kilometers and has not been involved in any accidents is referred to as an excellent-condition car. Here are the relevant explanations: 1. Original paint throughout: As normally understood, this phrase means the entire car retains its original factory paint, or at least all metal surfaces except the front and rear bumpers have original paint. The car may still have remnants of its original paint, and areas that have been repainted are indistinguishable to the untrained eye. 2. Original condition: 'Original condition' means the car's frame is intact and its sheet metal coverings (such as doors, hood, etc.) have not been removed. There is an emphasized term called 'original condition with original paint,' which normally means: not only has the car not been repainted, but its coverings have also never been removed.

Is there a regulation on the direction of the parked car's front?

There is no regulation on the direction of the parked car's front, but for convenience, it is recommended that car owners park with the car's front facing outward. Although the Road Traffic Safety Law does not explicitly mention that the front of the car must face a certain direction when parking, it clearly states that vehicles must not drive against the traffic and must follow road markings. Therefore, parking spaces on both sides of the road must be parked in the direction of travel, otherwise, starting the vehicle will inevitably result in driving against the traffic. Parking with the front facing outward facilitates vehicle rescue. Most cars have front-mounted engines, so if the vehicle malfunctions, there is more space for emergency repairs or jump-starting. When there is a fluid leak, parking with the front facing outward also makes it easier to detect, enhancing safety.

What does the SE button in the car mean?

The SE button in the car refers to mode switching. Here are the related explanations: 1. Economy Mode: In this mode, the vehicle reduces the fuel injection ratio, and the computer decreases the throttle opening to lower fuel consumption. However, the downside is reduced power performance. This mode is suitable for long-distance driving, such as on highways or national roads with constant speed driving. 2. Standard Mode: This mode uses the most standard driving plan, suitable for urban or rural road conditions. It offers a certain level of fuel efficiency while maintaining adequate power performance. 3. Sport Mode: This mode can be used on mountain roads or muddy surfaces. The vehicle does not prioritize fuel economy, focusing instead on power output, meaning the vehicle performs with greater strength.
