Does adding 92 octane gasoline once affect the Audi A6?
1 Answers
Audi A6 adding 92 octane gasoline once has some impact, but the impact is not significant. The details are as follows: 1. The biggest difference between 92 and 95 octane gasoline lies in the 3% n-heptane content. Standard gasoline is composed of n-heptane and isooctane, but since n-heptane has relatively poor anti-knock properties, the amount of n-heptane determines the type of engine it is suitable for. 2. If the wrong gasoline is added, the driving experience may include abnormal vibrations in the engine and even noise. Additionally, since the ignition timing of the engine does not change after a sudden change in fuel quality, it may lead to incomplete combustion or insufficient combustion. Therefore, during driving, especially during aggressive driving, the car may feel underpowered. 3. Some cars that usually use higher-octane gasoline may trigger an engine warning light if they suddenly use lower-octane gasoline once. This means a yellow engine icon may appear on the dashboard while driving. Generally, this icon will disappear on its own after refueling with 95 octane gasoline and driving for a while. 4. After running out this tank of gasoline, simply refill with 95 octane and continue using it. The manufacturing technology of car engines is already very mature, and engines are designed and manufactured with these possible minor mistakes in mind, incorporating such fault-tolerant mechanisms.
