Will Not Changing Engine Oil Increase Fuel Consumption?

Not changing engine oil will increase fuel consumption. Below is the relevant explanation: 1. Impact: Prolonged failure to change engine oil affects a car's fuel consumption. Not changing engine oil for an extended period significantly reduces its sealing, lubrication, and cooling functions, leading to decreased engine power and increased fuel consumption. 2. Specific reasons: During use, engine oil's performance gradually declines due to contamination and oxidation, and there is also some consumption. Simply topping up without changing can only compensate for the lack of oil quantity but cannot make up for the loss of lubrication performance. It's like mixing cold water with room temperature water; it can only become warmer, not cooler. Therefore, only adding oil without changing it will result in progressively worse performance.

How often should a vehicle remove iron particles?

Generally, vehicles should remove iron particles every 1 to 2 months. Below is relevant information about iron particles: 1. Function: Iron particles refer to metal particles floating in the air that can remove iron particle impurities from the car's paint surface and quickly dissolve oxidation layers and rust. They effectively eliminate iron particles from the car's paint, restoring its original smooth and glossy appearance. 2. Impact: Iron particle removers will certainly cause some damage to the car's paint. However, since the remover is used locally, it doesn't have much effect on the paint itself. During use, if you notice changes in the paint (turning purple), you should immediately rinse it off with clean water to minimize the damage caused by the remover.

What does it mean when abnormal tire pressure is detected?

Tire pressure monitoring showing an abnormality indicates that the air pressure in the four tires is outside the normal range. Here is relevant information: 1. Tire pressure: Tire pressure is essentially the blood pressure of a car, and it plays a crucial role in the vehicle's performance and power. When tire pressure is abnormal, the monitoring system does not prevent the car from being driven. Therefore, before each trip, the owner should perform a static check to ensure the tire pressure matches the specified value. If it does not, do not drive the vehicle. 2. Handling method: If abnormal tire pressure is detected while driving, immediately check the tire pressure. If the low-pressure warning light comes on, avoid sudden steering or emergency braking. While reducing speed, move the vehicle to the roadside and stop as soon as possible. Driving with low tire pressure can cause permanent damage to the tires and increase the likelihood of tire failure.

What to Do When You Forget to Bring Your Driver's License?

Currently, many cities allow this situation, and no points will be deducted or fines imposed. 2. When a traffic accident has occurred: An electronic driver's license is only valid when no traffic accident has occurred. If a traffic accident has occurred, the driver's license must be presented.
