Should Audi A6 use 95 or 92 octane gasoline?

[VonGabriel]

When refueling, it is recommended to use 95 octane or higher premium unleaded gasoline. Here are the relevant details: Power reduction: If 92 octane standard gasoline is used, the power output will decrease. In such cases, try to drive at moderate engine speeds with low load conditions and refill with premium gasoline as soon as possible. Do not use ethanol fuels with high ethanol content such as E30-E100, as they can damage the fuel system. Even a single instance of using leaded or other metal-additive fuels can cause long-term impairment to the exhaust catalytic purification function. It is advised to only use gasoline additives approved by Audi. Anti-knock agents: Anti-knock or anti-detonation additives may contain metal additives, which can severely damage the engine and exhaust catalyst. Since the vehicle is equipped with an exhaust catalytic converter, only unleaded gasoline is permitted for operation. The gasoline must at least meet the V standard and be sulfur-free. Fuels with up to 10% ethanol content (E10) are acceptable.
