What to Do If You Accidentally Filled 92 Instead of 95 Gasoline?

[Finn]

It's not a big issue if you accidentally fill up with 92 gasoline instead of 95 once or twice, but long-term mixing is not recommended. Here is some extended information about fuel: 1. Vehicles have specified gasoline grades, so mixing 95 and 92 gasoline is not advisable. 2. The mixtures of 92 and 95 gasoline are essentially the same, but the difference lies in their mixture ratios. Long-term use of mixed gasoline grades can reduce anti-knock properties, causing the engine to auto-ignite before the designated ignition time. This can lead to ignition system confusion, engine shaking, and in severe cases, damage to the car engine.
