Latest update date: February 06, 11

Car engine oil is a special fluid that plays a very important role in protecting and maintaining engine performance. It acts as a thin film, lubricating the moving parts inside the engine, reducing friction, wear and temperature.

When using a car as a means of transportation, changing the oil is very important and cannot be forgotten. Thanks to regular oil changes, cars can operate smoothly and have a long life. However, when changing the oil for a car, people are often confused because they do not know what type of oil to change, how often should they check it? To learn more about this issue, we invite you to refer to 1 Notes when changing car engine oil below.

When should I change my car's oil?

Typically, the car's oil change time will be stored in the User Manual in the Maintenance and Operation section. Therefore, you should not rely on estimates, make your own decisions based on your experience to change the oil.

There are many cars equipped with the feature to notify when the oil needs to be changed on the screen. The system will accurately measure the distance traveled and maintenance when the car runs to give the most accurate oil change time for the vehicle. If you get a warning then you need to change the oil immediately.

How often should you check your car's oil?

Normally, you need to check the oil level of the vehicle at least 1 per month. If the oil tank shows signs of leakage, it should be repaired immediately. People often test oil by the test method. When using the test stick to check the oil, the car should park in a flat terrain, turn off the engine.

Not only that, you need to check the color of the oil. When the oil is brown or black, everything is in good shape. When the oil is milky white, the coolant may have leaked slightly into the engine. If there are small metal particles in the oil, the motor is damaged, the car should be brought to a place of maintenance.

How often should the oil be changed?

The modern and high-end versions of cars are about 12.000 - 16.000 km or from 6 - 12 month, change the 1 oil times. However, all oils will dry out over time, so it is best to change the oil regularly every year to ensure engine performance and increase service life.

Do cars need synthetic oil?

On the market today, synthetic oil costs are more expensive than 3 - 4 times normal oil. Therefore, many experts believe that only use synthetic oil for cars when manufacturers require.

Synthetic oil is an oil designed to be used for the purpose of avoiding decomposition, so it has good heat resistance, extended service life, and helps to increase engine performance and life.

When cars have to move a lot, oil is easy to build up and the oil is often unable to heat the engine. Especially for vehicles used to haul or haul heavy loads, moving in areas with hot climates, synthetic oil is the best option.

Even if synthetic oil is used, the usage time is longer than regular oil, you still need to change the oil periodically.

FAQ – Frequently Asked Questions

1. How does engine oil viscosity affect vehicle performance?

Viscosity is indicated by the SAE number (e.g. 5W-30, 10W-40). The first number represents the viscosity at low temperatures, the second number represents the viscosity at 100°C. Modern vehicles often require lower viscosity oils (0W-20, 5W-30) for optimal performance and fuel economy of about 2-3%.

2. How to recognize degraded engine oil?

In addition to color, check the viscosity (not too thin), smell (no gasoline smell), and clarity (no sediment). Degraded oil will increase fuel consumption by 5-8% and reduce engine power by about 10-15%. Read the article now: The reason why car engines quickly consume oil shared by many experts.

3. What is the optimum operating temperature of engine oil?

Engine oil works best at temperatures between 90-105°C. At temperatures above 120°C, the oil will begin to break down and lose its lubricating ability. Below 60°C, the oil has not yet reached its optimum viscosity.

4. Why do diesel cars need different oil than petrol cars?

Diesel engines operate at 25-30% higher pressure and 15-20°C higher temperature than gasoline engines. Diesel engine oil needs to have twice the oxidation resistance and soot dispersion.

5. Is recycled motor oil safe?

API-compliant recycled motor oil is safe to use, reducing energy production by 85% compared to new oil. However, it should only be used from reputable manufacturers and should account for no more than 30% of the replacement oil.
