Engine auto start-stop does not harm the engine, but it has a greater impact on the starter motor and battery. Here are the detailed explanations: Reasons why auto start-stop does not damage the engine: The engine auto start-stop is mainly used for brief stops, such as waiting at traffic lights. During this time, the engine temperature is normal, and the oil and various lubrication systems are also in normal condition, so the wear on the engine is negligible. Impact of auto start-stop on the starter motor and battery: The starter motor experiences increased wear during frequent starts, which reduces its lifespan. Additionally, it places a significant load on the vehicle's battery, so regular checks of the starter motor and battery are necessary.

As a frequent city commuter, I've been using the auto start-stop feature in my car for nearly three years, and the engine has been running perfectly. The manufacturer reinforced the starter and lubrication system during design, ensuring smooth starts. The fuel-saving advantage is particularly noticeable; it reduces fuel consumption during prolonged idling in traffic, saving me dozens of dollars on average each month. Although the battery might need replacement earlier, requiring a check every two years, overall, it doesn't harm the engine. The key is to maintain regular maintenance, clean carbon deposits, and inspect the battery, avoiding using the start-stop feature in harsh weather or on steep slopes. Modern cars have undergone countless tests, proving that start-stop causes minimal engine wear—don't fear it. Focus more on actual driving habits, avoid aggressive acceleration, and let the feature work naturally for a worry-free and eco-friendly experience.

I've been driving for over a decade and have used several cars with auto start-stop systems, never experiencing engine failures. This feature works wonders in areas with frequent traffic lights - the engine shuts down quietly and restarts swiftly, with reinforced starter mechanisms designed to withstand repeated cycling. As long as engine temperatures remain properly controlled without overheating, it's perfectly fine. You might go through batteries a bit faster, but overall the system is safe and reliable. The fuel savings are noticeable, putting real money back in your wallet long-term. The key is maintaining proper servicing with quality parts - do that and engine longevity won't be compromised. Give it a fair try, and once accustomed, you'll appreciate this smart technology.

What brand are the original brake pads for Volvo?

Volvo's original brake pads are from the German brand Jurid. Here is some relevant information about brake pads: 1. Classification of brake pads: Asbestos brake pads (mostly obsolete), semi-metallic brake pads, low-metallic brake pads, NAO formula brake pads, ceramic brake pads, and NAO ceramic brake pads. 2. Ceramic brake pads vs. traditional brake pads: In traditional brake pads, metal is the primary material that generates friction, providing strong braking force but with higher wear and a tendency to produce noise. After installing ceramic brake pads, no abnormal squealing occurs during normal driving. 3. Stable friction coefficient: Ordinary brake pads with immature friction materials can have excessively high friction coefficients, leading to unsafe factors such as loss of control during braking, pad burning, or scratching of the brake disc. Even when the brake disc temperature reaches 650 degrees, the friction coefficient of ceramic brake pads remains around 0.45-0.55, ensuring the vehicle maintains excellent braking performance.

What type of engine oil does the Mazda Axela use?

Mazda Axela uses original 0W20 full synthetic engine oil and 5W30 semi-synthetic engine oil. Engine oil specifications reference: The "W" stands for winter, and the smaller the number before it, the better the low-temperature fluidity of the oil, indicating a lower usable environmental temperature and better engine protection during cold starts. For example, 5W represents resistance to external low temperatures of -30°C, while 20W withstands -15°C. The number after the "W" indicates the oil's high-temperature resistance. The larger the number, the better the oil's protective performance at high temperatures. For instance, 40 represents a kinematic viscosity standard between 12.5mm2/s and 16.3mm2/s at 100°C. Engine oil grades are represented by a combination of two letters. The "S" series denotes engine oils for gasoline engines, with specifications ranging from SA to SN (in alphabetical order, excluding SI). Each subsequent letter indicates better performance, with more additives to protect the engine. Higher letters denote higher quality grades, with most international brands offering oils above SF grade. The "C" series represents diesel engine oils. If both "S" and "C" are present, the oil is suitable for both gasoline and diesel engines. Notes on changing engine oil: Engine oil should be changed regularly, and different types should not be mixed. Full synthetic oil should be changed every 8,000-10,000 km, semi-synthetic every 5,000-8,000 km, and mineral oil around 5,000 km. Regularly clean the engine filter and replace the oil filter. After adding oil, sludge and carbon deposits on engine parts disperse into the oil, causing it to darken over time. Typically, the oil's viscosity determines when it needs changing, not just its color. Insufficient oil can lead to inadequate lubrication and cylinder scoring, while excessive oil can reduce vehicle performance and increase fuel consumption.

Does the Dash Cam Need to Be Charged?

When the vehicle is started, the dash cam operates using the power supplied by the car and automatically charges simultaneously, eliminating the need for manual charging. After the vehicle is turned off and power is cut, the dash cam switches to its own battery, but the battery capacity is small and cannot provide power for extended periods. Connecting the device directly to the car battery can cause prolonged discharge, which may affect the battery's lifespan. Simply connecting the dash cam's power cable—whether through a cigarette lighter adapter or built-in wiring—ensures automatic charging when the vehicle is started. It is normal for the battery icon to remain red during power usage. The primary function of a dash cam is to prevent fraudulent claims. In cases where accident scenes lack clear evidence or have been tampered with, the dash cam can provide valid video evidence. For minor collisions, it offers reliable visual proof, allowing both drivers to quickly leave the scene without waiting for traffic police, thus avoiding road congestion. During unexpected road incidents, the dash cam can also supply credible evidence and news leads. When connected to a direct power source, the dash cam can serve as a parking monitor.

What Causes a Rattling Sound When Turning the Steering Wheel While Stationary?

When you hear an abnormal sound while turning the steering wheel while stationary, it is likely due to the friction between the spring steel piece of the horn wire transmission and the steering wheel. Typically, the sound originates from inside the vehicle and resembles a metallic rustling noise. The solution is to apply some lubricating oil at the friction point between the spring steel piece and the steering wheel. Below are the reasons for abnormal steering wheel sounds: 1. Sound from the turn signal reset: If the turn signal is activated while turning, the sound may come from the rebound clip of the turn signal's automatic reset mechanism. This is a normal occurrence, but the driver should confirm it. 2. Abnormal sound from within the steering wheel: If the sound comes from inside the steering wheel, it is most likely caused by the clock spring (spiral cable) of the airbag. To address this, remove the steering wheel airbag clock spring, apply some grease, and check if the sound persists. If it does, replace the clock spring as it may be damaged. 3. Aging of the steering tie rod end: If the steering tie rod end is aged, it can cause the steering wheel to vibrate and produce noise. In such cases, the steering tie rod end should be replaced, followed by a four-wheel alignment.
