[Car Tips] How often should car engine oil be changed? What is the difference between synthetic oil and mineral oil?
How often should a car's engine oil be changed?
1.Generally recommended replacement cycle
- Traditional advice : Replace every 5,000 km or six months (whichever comes first).
- Modern cars and synthetic oil : Change every 8,000~10,000 kilometers or once a year.
- High performance or special models : Please follow the original manufacturer's manual recommendations.
2. Factors affecting the replacement cycle
- Type of engine oil (synthetic oil/mineral oil/semi-synthetic oil)
- Driving environment (stop-and-go driving in urban areas, long-distance highway driving, climate, etc.)
- Vehicle age and engine condition
- Driving habits (vigorous driving should shorten the replacement cycle)
3. How to determine whether to change the oil?
- Follow the dashboard reminder or the manufacturer's manual .
- The engine oil becomes dark, thinner and has an odor.
- The engine becomes noisy or runs rough.
What is the difference between synthetic oil and mineral oil?
1. Mineral oil
- Source : Directly extracted from crude oil.
- Characteristics : The molecular structure is relatively uneven, the stability is poor, and it is suitable for general vehicles and normal purposes.
- Replacement cycle : Usually short (about 5,000 kilometers).
- Price : Relatively cheap.
2. Synthetic oil
- Source : Artificial synthesis, the molecular arrangement is more detailed and uniform.
-
characteristic :
- Good high and low temperature resistance.
- Strong anti-oxidation and anti-deterioration capabilities.
- Provides better lubrication protection and extends engine life.
- Replacement cycle : long (up to 8,000~15,000 kilometers).
- Price : relatively expensive, but high CP value.
3. Semi-synthetic oil
- Composition : Mineral oil mixed with synthetic oil.
- Features : Somewhere in between, with a balance between price and performance.
Small conclusion
- When to change the engine oil : Please adjust according to the manufacturer's recommendations and your own vehicle conditions. If the driving environment is bad or the driving habits are intense, it is recommended to shorten the replacement cycle.
- Choosing the type of engine oil : For ordinary household cars, mineral oil or semi-synthetic oil is sufficient. If you value engine protection and often drive long distances at high temperatures or at high speeds, it is recommended to use synthetic oil.
Tips:
Failure to change the engine oil for a long time will cause engine wear, sludge accumulation, and even shorten the engine life. Regular oil changes are the key to the longevity of your car!
