Many car owners are faced with the choice of adding 92 or 95 gasoline when refuelingWhile the main difference between these two gasolines is the additives and sulfur content, the wrong choice can have a certain impact on the vehicle. So, if you still have half a tank of 92 gasoline in the tank, is there any problem with adding 95 gasoline?
First of all, we need to understand the main differences between 92 and 95 gasoline. In fact, the gasoline we use is refined from No. 90**. Compared with 95 gasoline, No. 92 gasoline has fewer additives and is therefore more prone to carbon deposits. The 95 and 98 gasoline is better than the 92 gasoline. In automobile use, we generally believe that high-grade gasoline should be selected when the compression ratio is high, and low-grade gasoline should be selected when the compression ratio is low. The gasoline grade determines its anti-knocking ability, and the higher the grade, the stronger the anti-knocking ability.
So, if you add 92 gasoline when you still have half a tank of 95 gasoline in the tank, will there be any problems?Actually, it depends on the engine and tank design of the vehicle. If the vehicle's engine and tank design allow for the use of a higher grade of gasoline, then the inclusion of 95 gasoline is no problem at all. Doing so not only improves fuel economy, but also reduces the generation of carbon deposits.
However, if the vehicle's engine and fuel tank are designed to work only with 92 or lower gasoline, then adding 95 gasoline can cause some problems. High-grade gasoline can cause deviations in the ignition advance angle of the engine, which can affect the engine's power and fuel economy. In addition, if there is still residual 92 gasoline in the tank, adding 95 gasoline may cause two different grades of gasoline to mix together, which will affect the performance of the fuel.
In summary, if you are unsure whether your vehicle is suitable for higher grades of gasoline, it is best to consult the vehicle manufacturer or professional repairer first. When refueling, it is also best to use gasoline that matches the label recommended by the vehicle manufacturer to ensure the best performance and fuel economy of the vehicle.
