Can You Still Drive with Overheated Engine Oil?

The normal operating temperature of engine oil is generally between 70-90°C. In cases of overheated engine oil, it is recommended that the vehicle owner should not continue driving. Overheated engine oil will cause a decrease in oil viscosity, leading to increased friction and wear on various components, and shortening the engine's lifespan. Below are the effects of overheated engine oil: 1. Oil burning: Excessive engine temperature causes the oil viscosity to decrease, resulting in oil burning and the inability to form an oil film to protect the friction surfaces of components, accelerating part aging. Reduced oil viscosity also weakens sealing performance. 2. Premature fuel combustion: High engine temperature causes the fuel injected into the cylinders to ignite prematurely, reducing cylinder compression force and lowering power output. Additionally, parts expand due to heat, leading to jamming during operation, significantly reducing bearing performance and efficiency, and causing a series of adverse consequences.

How to Activate Cruise Control in the 2021 Nissan Qashqai?

To activate cruise control in the 2021 Nissan Qashqai, simply turn on the cruise system, press the activation button, and set the current speed. Below is relevant information about cruise control: 1. Introduction: Cruise Control System (CCS), also known as speed control system or autonomous driving system, allows the vehicle to maintain a constant speed set by the driver without the need to press the accelerator pedal. This feature reduces driver fatigue during long highway drives and minimizes unnecessary speed fluctuations, thereby saving fuel. 2. Working Principle: In simple terms, the cruise control system works by comparing the pulse signals from the vehicle speed sensor with the preset speed via the cruise control module, which then sends commands to the servo mechanism to adjust the throttle opening. This ensures the vehicle maintains the set speed. Electronic multifunction cruise control systems eliminate the mechanical components of traditional cable-operated systems, utilizing precise electronic control for enhanced accuracy and reduced mechanical failure risks.

How to Deal with Car Door Squeaking?

Regularly adding lubricating oil can help maintain and prevent car doors from squeaking. Here is some relevant information: 1. Door Limiter: The door and the car body are connected by a door limiter. You can open the door to its maximum angle, clean the grease and dirt on the limiter arm, limiter pin shaft, and connecting bracket surface, and then apply an appropriate amount of lubricating grease to the upper and lower surfaces of the arm. 2. Sealing Strip: Check if the door sealing strip has aged. Since the sealing strip is made of rubber, it will gradually age and deteriorate over time, which can cause noticeable wind noise and friction sounds for the driver and passengers. If the sealing strip is aged or damaged, it is recommended to replace it directly. Also, regularly clean the dust and rainwater from the gaps in the sealing strip during daily car use to prevent aging.

What is the method for changing a car tire?

To change a car tire, first take out the spare tire, wrench, jack, and other necessary tools. If the tire bolts have anti-theft features, the owner needs to find the tool to remove them. Then, loosen the bolts of the damaged tire—just loosen them, do not remove them completely at this stage. Next, position the jack under the car, ensuring it is correctly placed and not pressing against the car's body panels. Once the car is lifted, remove all the bolts from the tire to be replaced and store them safely. Pull the wheel until it is completely detached. If the nuts are stuck, tap them gently with a hammer, being careful not to overdo it to avoid damaging the brake pads. As a precaution in case the jack fails, place the removed flat tire flat under the car. Finally, install the spare tire. Precautions when changing a car tire: Park the car on a flat surface or in a location where the operation can be performed conveniently without obstructing others, avoiding any possibility of the car rolling forward or backward. When tightening the bolts on the spare tire, first tighten all bolts to a uniform tightness, then fully tighten them in a diagonal sequence. Regularly inspect the spare tire, primarily checking tire pressure, wear, and any cracks. Replace the tire before the tread wears down to the wear indicator line. If there are fine cracks on the tire sidewall, avoid using it for long-distance or high-speed driving, as the sidewall is thinner and more prone to blowouts at high speeds.
