When each car leaves the factory, the manufacturer will remind the owner to add a certain number of gasoline. Ordinary family scooters plus No. 92 gasoline can be German cars and some high-end cars need to add No. 95 gasoline, or even No. 98 gasoline. Different grades of gasoline have different prices and different knock resistance.
Gasoline is labeled to represent isooctane content, 92 gasoline means 92% isooctane, and 95 gasoline means 95% isooctane. What will happen to the car that has been refueled with No. 92 gasoline for a long time replaced by No. 95 gasoline?
Some car owners occasionally add No. 95 gasoline, do not feel much change, if you can add No. 95 gasoline for a long time, the change will be very obvious after three months.
First, I feel more motivated.
Mr. Chen, a Zhejiang owner, bought a Toyota Camry, which used to be filled with No. 92 gasoline and started adding No. 95 gasoline three months ago. When he first added No. 95 gasoline, Mr. Chen did not notice any changes, and the driving experience of the car was similar to before.
After driving the car for more than two months, Mr. Chen found that the power was significantly stronger than before. This is because No. 95 gasoline has better explosion resistance gas, and knocking is avoided during gasoline combustion. In the past, when Mr. Chen added No. 92 gasoline, the driving computer would automatically postpone the ignition time of the spark plug, and the engine power would be worse, and now after adding No. 95 gasoline, the engine ignited in advance, and it was obvious that the power had changed.
Second, there is less engine noise.
The better the knock resistance of No. 95 gasoline, the noise of the No. 95 gasoline engine will indeed be reduced in the long run. We should pay attention to the fact that the reduction of engine noise by adding No. 95 gasoline is not obvious, and adding high-grade gasoline can only appropriately reduce engine noise, and the owner feels that the car is quieter, a large part of the reason is psychological cues.
Third, fuel consumption is reduced.
Theoretically, the thermal efficiency of No. 92 gasoline and No. 95 gasoline is similar, and replacing high-grade gasoline will not affect the range. However, many car owners reflect that adding No. 95 gasoline does feel that the fuel consumption is lower, the fuel consumption is not obvious, and the fuel consumption of 100 kilometers will be reduced by 0.1 liters to about 0.3 liters.
Xiaobian believes that the owner feels that the fuel consumption of No. 95 gasoline is low, which may be because the driving habits of the owner have changed. Many car owners do not dare to step on the accelerator and brakes after adding high-grade gasoline, and the driving habits of car owners have become better, and fuel consumption will naturally decrease.
Should a car with No. 92 gasoline be added to no. 95 gasoline? I think that the owner only needs to refuel according to the manufacturer's suggestion, and there is no need to deliberately increase the specification of gasoline. Luxury cars require higher-grade gasoline because the engine is more powerful and need gasoline with better explosion resistance gas.
Ordinary family scooters do not need to add No. 95 and No. 98 gasoline, the original design of Japanese cars is to save fuel, and the engine fully takes into account the factors of knock resistance. For a long time to add No. 95 gasoline to the Japanese car with No. 92 gasoline, the change in power is not obvious, and it will also lead to an increase in the cost of car maintenance.
Now that the price of gasoline in the mainland is getting more and more expensive, there will be a new round of oil prices on March 17. After the oil price rises again, the price of No. 95 gasoline is likely to break through the 9 yuan mark, and everyone only needs to add gasoline that suits them, and there is no need to increase the gasoline label.
