What is the best gasoline grade for a new car?

[CarterDella]

It is best to refuel the car according to the gasoline grade required by the vehicle. That is, if the vehicle recommends 92 gasoline, it is best to add 92 gasoline; if it recommends 95 gasoline, it is best to add 95 gasoline. This depends on the brand and model you are referring to. The selection of the fuel label can be seen on the label on the back of the fuel tank cap or in the car maintenance manual. Check the inside of your car's fuel tank cap. Most models are described here. Alternatively, check the compression ratio of your car's engine. Generally, if it is less than 9.5, add 92; if it is greater than 9.5, add 95. Many people think that adding 93 or 97 is better for the car and that the oil is cleaner. In fact, this is incorrect. It depends on how suitable the car is for a particular gasoline grade.
