What happens if motor oil is not changed for a long time?

The consequences of not changing the oil for a long time are as follows: 1. If the oil is not changed for a long time, as the oil's lifespan deteriorates, its lubrication ability will rapidly decline, preventing the engine from receiving proper lubrication and leading to abnormal wear. 2. Metal debris cleaned by the oil cannot be expelled and accumulates inside the engine, causing dirt and generating a large amount of sludge. 3. The engine may experience increased fuel consumption, reduced power, difficulty starting, abnormal shaking, and poor operation. In severe cases, the engine may be directly rendered unusable. Here are the functions of motor oil: 1. Lubrication: There are many moving friction surfaces inside the engine. The oil forms a film between these surfaces to achieve lubrication and anti-wear effects. 2. Cleaning: The movement of engine components causes wear and produces metal debris. The oil continuously circulates inside the engine through the action of the oil pump and carries these metal debris back to the oil pan. 3. Cooling: The continuous circulation of oil inside the engine can carry away the heat generated by the engine and cool it through the oil cooler. 4. Sealing: The oil film formed on the surface of the engine cylinder walls and the inner surface of the valve guides can provide a sealing effect to prevent leaks.

What causes the gear grinding when the Lavida's gear shift is not fully engaged?

If the gear grinding sound heard when shifting is very intense, it may indicate that the gear is possibly damaged. If the sound is moderate, it could be due to the following reasons: Clutch malfunction: Mechanical failure of the clutch prevents it from disengaging properly, leading to gear grinding during shifting. Operational reasons: This refers to improper use of the clutch, where the driver shifts gears without fully disengaging the clutch, resulting in a clicking noise and difficulty in engaging the gear. Gear grinding can cause long-term damage to the transmission. Looking down at the gear lever while shifting: Prolonged driving in low gear can also lead to this issue. Generally, higher gears are more fuel-efficient than lower gears, so it is advisable to upshift promptly after starting the vehicle.

What does the ECT button on the Toyota Camry mean?

ECT is the transmission electronic control mode switch. When turned on, it operates in a sporty mode with increased torque but higher fuel consumption; when turned off, it functions in an economical mode, saving more fuel. Pressing the ECT button during rapid acceleration or downhill driving can automatically complete the downshifting process. Here are some additional details: 1. For example, when driving downhill in D gear, the vehicle speed may become too high, and frequent braking can cause the brake pads to overheat and the system to fail. Pressing the ECT button and applying the first brake will automatically downshift the transmission, keeping it within 3rd gear. 2. Lightly and gently press the accelerator and maintain it. The engine and the ECT electronically controlled automatic transmission will work in harmony to gradually increase speed, keeping the engine at just over 2000 RPM, while the transmission smoothly shifts gears to accelerate. 3. Press the accelerator slightly faster and deeper, then gradually ease off and maintain the desired speed. The engine and the ECT electronically controlled automatic transmission will work in harmony to accelerate more quickly, with the transmission smoothly and responsively shifting gears. 4. Press the accelerator faster and deeper, then gradually ease off and maintain the desired speed. Again, it's important to ease off the accelerator to keep the engine at just over 2000 RPM. Excessive speed and frequent braking can cause the brake pads to overheat and the system to fail. Pressing the ECT button and applying the first brake will automatically downshift the transmission.
