What to pay attention to when changing from 92 to 95
I believe there are many friends who should pay attention to changing from 92 to 95? I want to understand this issue, so I will give you a brief introduction today, I hope it can help you.
There is no need to pay attention to changing from 92 gasoline to 95 gasoline, and the 92 and 95 mixed plus will not have any problems. If your car's engine can't add 92 # gasoline, don't mix it.
Different grades of gasoline have different octane numbers, and higher grades have higher octane numbers.
The higher the octane number, the better the gasoline stability.
General turbocharged engines require a minimum of 95 gasoline, which can prevent knocking in the engine.
Knocking is an abnormal combustion phenomenon in the engine. When the piston is in the compression stroke, the piston will run upward to compress the combustible mixture. At this time, the temperature and pressure of the combustible mixture will increase.
If the stability of gasoline is not good, the combustible mixture will burn ahead of time, which is the knock.
The burning combustible mixture will push the piston down, and the piston is running upward at this time, which will affect the engine's power output and fuel economy.
Severe knocking can even cause the piston to burst or deform the connecting rod.
Therefore, when you refuel, you must choose a gasoline label suitable for your car engine.
If you need a minimum of 95 gasoline, don't use less than 95 gasoline.
If 92 gasoline can be used, there is no need to use higher grade gasoline.
When refueling, be sure to go to a large gas station with a better quality.
