How do oil numbers differ?
In daily life, we often encounter different types of oil, such as gasoline, diesel, engine oil, etc. Each oil has its own unique uses and properties, and the oil number is an important identifier to distinguish them. This article will introduce in detail how to distinguish oil numbers, and attach structured data to help you better understand.
1. The difference between gasoline oil numbers
Gasoline is one of the most common fuels, and different grades of gasoline are suitable for different engines. The following are common gasoline oil numbers and their characteristics:
| Oil number | Octane number | Applicable models | Features |
|---|---|---|---|
| No. 92 | 92 | Ordinary family car | Economical and suitable for low compression ratio engines |
| No. 95 | 95 | Mid- to high-end models | High combustion efficiency, suitable for high compression ratio engines |
| No. 98 | 98 | high performance car | Strong blast resistance, suitable for luxury cars and sports cars |
2. The difference between diesel oil numbers
Diesel is mainly used in diesel engines, and its oil number is usually distinguished by its freezing point. The following are common diesel oil numbers and their characteristics:
| Oil number | Freezing point (℃) | Applicable season | Features |
|---|---|---|---|
| No. 0 | 0 | spring summer autumn | Suitable for warm climates, less expensive |
| -No. 10 | -10 | winter | Suitable for low temperature environments to prevent solidification |
| -No. 20 | -20 | severe cold areas | Remains fluid in extremely cold weather |
3. The difference between engine oil numbers
Engine oil is the lubricant of the engine, and its oil number is usually distinguished by viscosity grade. The following are common engine oil numbers and their characteristics:
| Oil number | Viscosity grade | Applicable temperature | Features |
|---|---|---|---|
| 5W-30 | 5W-30 | -30℃ to 30℃ | Universal for all seasons, suitable for most models |
| 10W-40 | 10W-40 | -20℃ to 40℃ | Suitable for high temperature environment and protect engine |
| 0W-20 | 0W-20 | -40℃ to 20℃ | Specially designed for extremely cold areas, with good low-temperature starting performance |
4. How to choose the appropriate oil number
When choosing the right oil number, you need to consider the following factors:
1.vehicle manual: Different models have different requirements for oil number. Be sure to refer to the vehicle manual.
2.climatic conditions: Low pouring point diesel or low viscosity engine oil should be selected in cold areas.
3.Engine type: High compression ratio engines require high octane gasoline.
4.Economy: Choose the appropriate oil number according to your budget to avoid unnecessary waste.
5. Summary
The difference in oil number is mainly reflected in the octane number, pouring point and viscosity grade. Gasoline, diesel and engine oil each have their own unique oil number system. Choosing the right oil number is crucial to the performance and life of the vehicle. I hope the structured data in this article can help you better understand the differences between oil numbers and make wise choices in actual use.
