Does Mixing Engine Oils Affect the Car?

1 Answers

Mixing engine oils can indeed affect the car, especially during winter. Combining oils of different specifications and types may lead to reduced lubrication efficiency and a lower freezing point of the oil, making it more prone to freezing. Once the oil freezes in winter, it can cause the engine block to crack, resulting in severe issues. More information about automotive engine oil is as follows: 1. The oil used in motor vehicles is engine lubricant, which serves to lubricate, form protective films, and assist in cooling the engine. 2. Engine oil is often referred to as the 'blood' of a car, as its quality directly impacts the engine's power and performance. It is advisable to avoid mixing different types of oils and instead use a single specification for top-ups. Frequent mixing of oils may negatively affect the engine.

What do I need to bring for Subject 4?

For the Subject 4 exam, you only need to bring your ID card; no other items are required. The Subject 4 exam consists of 50 questions, primarily in the form of case studies, images, and animations, with a perfect score of 100 and a passing score of 90. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 exam was divided into two parts: the road test and an additional safety and civilization knowledge test, commonly referred to as "Subject 4," which evaluates "driving ethics." Since this test is conducted after Subject 3, it is commonly called the Subject 4 exam. Officially, there is no such term as Subject 4. If you fail Subject 4, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own, and no retake fee is required. There are no restrictions on the number of retakes, but the validity period of the driving skills test permit is three years. If the applicant fails to complete the exam within this period, the results of the previously passed subjects will become invalid.

What is the difference between China VI and China VIB?

China VI is more environmentally friendly than China V, with higher requirements for vehicle exhaust emissions. Both China VI and China V refer to the national automobile emission standards, officially known as "Limits and Measurement Methods for Emissions from Light-Duty Vehicles." The difference lies in the stages at which these standards were formulated. The purpose of these standards is to control and reduce vehicle emissions and improve ambient air quality. The differences between China VI and China V are as follows: 1. Different implementation times: The China VI standard was implemented in December 2014, while the China V standard was implemented in December 2017. 2. Different sulfur content limits: The China VI standard specifies a sulfur content of no more than 50mg/kg, whereas the China V standard specifies a sulfur content of no more than 10mg/kg. 3. Different particle number limits: Taking passenger cars as an example, nitrogen oxide emissions for gasoline vehicles are 25% stricter, and for diesel vehicles, they are 28% stricter. The China V standard introduced a new limit on particle numbers, with particle emission limits being 82% stricter under the China V standard. 4. Different durability mileage: The durability mileage for pollution control devices under the China V standard has doubled, increasing from the original 80,000 kilometers to 160,000 kilometers. This means that within 160,000 kilometers, vehicle emissions should meet the standard's limit requirements. 5. Different environmental protection levels: Compared to China IV, China V has higher emission standards and a higher environmental protection level.

What causes the steering wheel light to turn yellow?

The steering wheel light illuminates due to a generator malfunction. Unstable power supply can cause the steering wheel light to come on. Loose connections in the power steering system may lead to partial leakage of steering fluid. A faulty power steering pump can also trigger the steering wheel light, resulting in abnormal steering. Below is an introduction about the steering wheel: Introduction: The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Function: The steering wheel's function is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Composition: It mainly consists of a skeleton, foam, and installation clips or screw holes corresponding to the driver's airbag (DAB).

What Causes a Diesel Vehicle with Fuel to Fail to Start?

Here are the reasons why a diesel vehicle with fuel fails to start: Engine fuel line blockage: Check if the engine fuel line is unobstructed. If you hear a hissing sound from the fuel injector, it indicates the fuel line is functioning properly. Cylinder compression: Inspect the cylinder compression. If the flywheel can rotate after releasing the decompression device, but the cylinder compression is problematic, the cylinder piston and piston rings need replacement. Lubricating oil: Replace the lubricating oil promptly. Overly viscous lubricating oil can hinder smooth engine startup. Fuel pump: Check for air in the fuel pump. If there is air inside the fuel pump, the diesel engine will fail to start.
