Today we are going to delve into a controversial topic among car owners - if the vehicle recommends the use of 92 gasoline, then whether it is reasonable and economical to add 95 gasoline to it for a long time. First of all, we need to understand the essential difference between 92 and 95 gasoline.
The core difference lies in the octane number of the two, which is a key indicator of gasoline's anti-knock performance. Due to its higher octane number, No. 95 gasoline has greater knock resistance, allowing the engine to operate at a larger compression ratio, resulting in an earlier ignition time. Theoretically, this will result in higher combustion efficiency, better power performance and lower fuel consumption, as well as help reduce the formation of carbon deposits and improve the overall performance of the engine.
However, for a model that only needs 92 gasoline, blindly pursuing a high grade does not necessarily mean an absolute advantage. While 95 gasoline does reduce engine noise and improve fuel economy by improving knock resistance and combustion, it is significantly higher than 92 gasoline. According to market data, the average price per litre of 95 petrol is 10%-20% higher, which means that the continued use of 95 petrol for engines designed to accommodate 92 petrol can be an unnecessary financial burden if not necessary.
It is worth noting that the car manufacturer has made precise adjustments to the recommended gasoline grades during the development phase, including the various performance parameters of the engine are optimized around the corresponding gasoline grades. Therefore, for vehicles that recommend using 92 gasoline, simply refuel according to the manufacturer's recommended standards to ensure the optimal operation of the engine.
Of course, for some car owners, out of love for the vehicle or looking for a better driving experience, it is also an acceptable choice to choose to use 95 gasoline occasionally or for a long time. Although this approach will increase fuel expenditure, it may indeed improve the vehicle's acceleration response and engine noise control during actual driving.
However, for those old models that have been driven for many years, especially those with serious internal wear and tear on the engine, even if 95 gasoline is added, due to hardware limitations, it may not be able to give full play to the advantages of high-grade gasoline, and the additional cost invested will not bring obvious benefits, but it is not cost-effective.
In summary, it is not impossible to fill a No. 92 petrol vehicle with No. 95 petrol, but after weighing the pros and cons, we should be clear that this may not necessarily significantly improve the performance of the vehicle, but it will certainly increase the fuel cost. As a car owner, you should make an informed decision based on your vehicle condition, budget, and desired driving experience when deciding whether to "upgrade your consumption".
Here, we encourage our readers to actively participate in the discussion and share your real-world experiences and insights on the use of different grades of gasoline. At the same time, it also reminds the majority of car owners that in the process of daily car use, it is important to follow the fuel recommendations of the vehicle manufacturer to ensure that the car gets the most suitable "ration" for it. In the next issue, we will continue to delve into the field of car maintenance and bring more practical information, so stay tuned!
