What does 8 to 9 oil mean?
2 Answers
When users often say 8 oil or 9 oil, it refers to consuming 8 liters or 9 liters of fuel per 100 kilometers. By calculating fuel consumption multiplied by fuel price divided by 100 kilometers, you can determine the cost per kilometer. Since cars often experience various driving conditions such as acceleration, deceleration, braking, and engine idling during actual operation, the constant-speed fuel consumption is usually lower and significantly different from the actual fuel consumption. This difference is even more pronounced for cars frequently used for short-distance urban driving. Below is an introduction to gasoline grades: 1. 90-octane gasoline: Suitable for gasoline cars with an engine compression ratio below 8.5. 2. 92-octane gasoline: Suitable for gasoline cars with an engine compression ratio between 8.6 and 9.9. 3. 95-octane gasoline: Suitable for gasoline cars with an engine compression ratio between 10.0 and 11.5. 4. 98-octane gasoline: Suitable for gasoline cars with an engine compression ratio above 11.6.
I've been driving for over thirty years, and the term 'eight to nine liters' is quite common. It refers to the car consuming 8 to 9 liters of gasoline per 100 kilometers. This reflects the car's fuel consumption level. For example, my old car uses about 8 liters on the highway, but in city traffic with congestion, it can easily go above 9 liters. Fuel efficiency is closely related to the size of the vehicle—SUVs generally consume more fuel than compact cars. Driving faster or using the air conditioning can also increase fuel consumption. Remember, regular maintenance and checking tire pressure can help reduce fuel consumption and save some money. Always pay attention to the actual fuel consumption while driving, not just the manufacturer's labeled data, as real road conditions can make a big difference.
