Is it necessary to add gasoline additive for a new car?

[MacCharlotte]

New cars do not need gasoline additive. The relevant introduction about 95 gasoline is as follows: Introduction to 95 gasoline: 95 gasoline is 95% isooctane and 5% n-heptane. When the engine compression ratio is high, high-octane gasoline should be used. If low-octane gasoline is used with a high compression ratio, it will cause abnormal combustion, resulting in knocking, increased fuel consumption, and weak driving performance. Introduction to refueling precautions: High-compression engines can use low-grade gasoline, but you should not blindly choose gasoline grade based on compression ratio. Instead, you should add the corresponding gasoline as required by the manufacturer.
