In the daily discussion of car owners, the choice of gasoline label is always a hot topic. Many drivers have wondered: If my car was originally recommended to use 95 petrol, would it be better to switch to 0 petrol? Will it have a negative impact on the vehicle? To answer these questions, we interviewed several experienced veteran drivers.

First of all, we need to clarify the meaning of gasoline labeling. Gasoline marking actually reflects the anti-knock performance of gasoline, that is, the ability of gasoline to resist knocking in the engine cylinder. The higher the grade, the better the gasoline's knock resistance. The main difference between petrol 95 and petrol 0 is their octane rating, with petrol 0 having a higher octane rating.

For those vehicles that recommend using 95 petrol in the vehicle manual, switching to 0 petrol will generally not cause damage. In fact, since No. 0 gasoline is more resistant to knockout, it may bring some benefits in some cases. For example, during high-load operation, No. 0 gasoline is less likely to cause knocking, which is an abnormal combustion phenomenon that can lead to a decrease in engine power, an increase in fuel consumption, and in severe cases, damage to engine components. Therefore, the use of No. 0 gasoline helps to reduce these risks and makes the engine run more smoothly.

Some veteran drivers reported that after switching to No. 95 gasoline, they felt that the vehicle was more energetic when accelerating, especially in occasions that require a large power output, such as overtaking or climbing. This is because No. 0 gasoline can bring the ignition advance angle of the engine closer to the optimal value, thereby improving combustion efficiency and improving power performance. More combustion also helps to slow down the formation of carbon deposits inside the engine. Excessive carbon deposits can affect the heat dissipation and compression ratio of the engine, resulting in reduced performance and increased fuel consumption. Therefore, from this point of view, the use of 0 gasoline is beneficial for the long-term health of the engine.

However, this does not mean that petrol 95 is the best choice for this type of vehicle. While these vehicles can run on 0 petrol, their engines are designed and tuned to the characteristics of 0 petrol. Long-term use of No. 0 gasoline may slightly increase the combustion temperature of the engine, increasing the burden on heat dissipation. Moreover, the price of 0 gasoline is usually higher, and from an economic point of view, the use of 0 gasoline increases fuel costs.

For vehicles that have been driven for a longer period of time, if there is some level of wear or carbon build-up inside the engine, there may be some temporary discomfort from suddenly switching from 95 to 0 petrol. For example, the engine's idle speed may become erratic, or there may be slight shaky while driving. This is because the engine's control system takes time to adapt to the new gasoline characteristics. But generally speaking, after a period of operation, the engine's computer will automatically adjust the parameters to bring the engine back to normal operation.

For high-performance engines or turbocharged engines, they require higher knock resistance to gasoline. Even if the vehicle manual recommends the use of No. 95 gasoline, the manufacturer may recommend the use of No. 0 gasoline for better performance. In this case, the use of No. 0 gasoline can better exploit the engine's potential, reduce the risk of knocking, and improve the power output and driving experience.

For vehicles that were originally recommended to use 92 petrol, switching to 0 petrol generally does not cause damage, but may have some positive effects in terms of power and carbon deposition. However, when making a choice, car owners also need to consider factors such as the design characteristics of the engine, the use of the vehicle, and the economic cost. If you have high requirements for vehicle performance and are not too concerned about the increase in fuel costs, then you can try using No. 0 gasoline. However, if you pay more attention to economy and vehicle stability, the use of No. 0 gasoline according to the vehicle manual can also fully meet the needs of daily driving.

Some car owners may be concerned about the impact of switching to a different grade of petrol on the vehicle's fuel system or emissions system. However, based on the experience of many experienced drivers and the advice of professional technicians, as long as the vehicle manual does not explicitly prohibit the use of a certain grade of gasoline, then switching to a different grade of gasoline usually does not cause damage to the vehicle's fuel system or emissions system. Of course, in order to ensure optimal performance and fuel economy, car owners should still choose the appropriate petrol grade according to the recommendations of the vehicle manual.
