What is the Difference Between Engine Oils?

1 Answers

Here are the key differences regarding engine oils:1. Choose the Type: Currently, there are two main types of engine oils available on the market: mineral oil and synthetic oil. Synthetic oil can be further divided into semi-synthetic oil and full-synthetic oil. The difference between them is quite simple—it lies in the base oil. Mineral oil is refined directly from crude oil without any chemical changes or artificial additives, similar to 'all-natural, additive-free' beauty products for women. Semi-synthetic oil is artificially produced based on mineral oil, while full-synthetic oil is entirely synthesized through chemical methods—a purely man-made product that represents a higher-grade option. Interestingly, unlike beauty products, chemically synthesized engine oils are actually better.2. Choose the Performance: Next, let’s discuss the performance differences. Synthetic oil has better fluidity at low temperatures compared to mineral oil, preventing solidification or freezing, which aids in cold starts for vehicles. In terms of high-temperature resistance, synthetic oil also outperforms mineral oil, providing better protection for high-revving engines. Additionally, synthetic oil has lower volatility and a longer service life than mineral oil, making it more durable—except for engines that burn oil. Due to differences in manufacturing processes and costs, synthetic oil is also more expensive than mineral oil.

What is the best method for repairing a car tire puncture?

There are five methods for repairing a car tire puncture: hot vulcanization, mushroom plug, cold patch, external plug strip, and using an integrated tire repair and inflation machine. Among these, hot vulcanization is widely recognized as the safest and most reliable tire repair method. Under normal circumstances, this method provides the best air-tightness and repair effect, as well as the strongest durability. The following are the functions of car tires: 1. Supporting weight: Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions. 2. Cushioning impact: Transmitting traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the car's power performance, braking performance, and passability; working together with the car suspension to cushion the impact during driving and dampen the resulting vibrations. 3. Ensuring car safety: Preventing car components from experiencing severe vibrations and premature damage, adapting to the high-speed performance of the vehicle and reducing driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.

What Does Mild Hybrid Mean?

Mild hybrid refers to mild hybrid power or light hybrid vehicles. Below is an introduction to mild hybrid vehicles: 1. Introduction to Mild Hybrid Vehicles: Mild hybrid technology changes the original power output method of vehicles. Mild hybrid vehicles generally use pure electric power to start, so there is minimal vibration and noise when starting the car. Mild hybrid vehicles are equipped with a power recovery system that recovers wasted energy when braking, charging the vehicle's battery to achieve energy saving and emission reduction. 2. Advantages of Mild Hybrid Vehicles: The use of a 48V mild hybrid system allows the vehicle to support higher-power onboard systems, drive more powerful start-stop motors, and more easily rotate the engine crankshaft to wake up the engine, reducing system delay and jerkiness. It can also enable more functions. Some 48V systems can even briefly take over the air conditioning when the engine is off, powering the air conditioning compressor to prevent the air conditioning from shutting down. Additionally, the 48V mild hybrid system can reduce energy consumption and emissions by approximately 15-20%.

How many more years can Beijing National 4 vehicles be driven?

Beijing National 4 vehicles can continue to be driven as long as they pass the annual inspection at the local motor vehicle inspection station. Below is some information about the National 4 emission standard: 1. Introduction: The National 4 emission standard is the fourth phase of China's motor vehicle pollutant emission standards. 2. Vehicle emission pollutants: Mainly include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. 3. Purpose: Through the application of technologies such as better catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard aims to control and reduce vehicle emission pollutants below specified levels.

Does a new car need an annual inspection after one year?

A new car does not require an annual inspection after one year. The law clearly stipulates that 5-seater vehicles enjoy a 6-year exemption policy for the first inspection. Although exempt from inspection within 6 years, it is necessary to apply for an annual inspection sticker every two years. The premise of exemption is that no major traffic accidents occur during this period. If an accident occurs, an online annual inspection must be conducted. Below are the regulations for the frequency of annual inspections for various vehicle types: 1. Non-operational small passenger vehicles: every 2 years for the first 6 years, every 1 year from the 7th to the 15th year, and every 6 months after 15 years. 2. Non-operational medium and large passenger vehicles and trucks: annual inspection once a year for the first 10 years, and every 6 months from the 11th year onwards. 3. Operational passenger vehicles: annual inspection once a year for the first 5 years, and every 6 months from the 6th year onwards.

Location of the windshield washer fluid in Lavida?

The windshield washer fluid filler port of Volkswagen Lavida is located on the right side of the engine compartment. Since windshield washer fluid is a consumable item, it should be checked regularly. There are usually scale marks inside the washer fluid reservoir for reference during refilling, and it's important not to exceed these marks. Below is relevant information about windshield washer fluid: 1. Definition: Commonly known as automotive windshield cleaning fluid. It is a consumable product in vehicle maintenance. High-quality automotive windshield washer fluid mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. 2. Functions: (1) Cleaning performance: Windshield washer fluid typically has wetting, penetrating, and solubilizing functions to achieve cleaning and stain removal. (2) Antifreeze performance: The presence of alcohol and ethylene glycol can significantly lower the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost.

Does idling with the AC on in summer damage the car?

It does not cause special damage to the car, but only normal wear and tear. The following are the effects of idling with the AC on: 1. Increased emission of harmful gases: Idling with the AC on emits more harmful exhaust gases than driving with the AC on, because idling is the worst working condition for the engine, where gasoline burns relatively incompletely, resulting in relatively higher emissions of harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides. 2. Significant harm to human health: Idling with the AC on can cause harm or even death to people inside the car if not careful. The main harms are two types: one is hypoxia and suffocation, and the other is carbon monoxide poisoning. When idling with the AC on, always do so in an open area, and never stay in the car for a long time in a confined small space, as the carbon monoxide emitted by the car can enter the vehicle, easily causing carbon monoxide poisoning.
