Can I add fuel additive the day after refueling?

[DiRosalie]

You can add fuel additive the day after refueling, but the effect is not as good as adding it before refueling. Adding before refueling: Adding fuel additive before gasoline will yield better results, as the additive can mix thoroughly under the impact of fuel injection. However, adding it afterward also works, as the additive will gradually mix with gasoline as the vehicle moves. It's worth noting that while fuel additives can indeed improve fuel characteristics, prolonged use may cause varying degrees of impact. Long-term use: For turbocharged engines, long-term driving can accumulate a lot of carbon deposits, and adding fuel additive at this time is beneficial for the car. However, this does not mean it should be used continuously for a long time, as it can easily clog the three-way catalytic converter.
