Can the Audi A3 use 92 octane gasoline?
2 Answers
Audi A3 cannot use 92 octane gasoline. It is better to use higher octane gasoline for the following reasons: 1. Low octane gasoline will reduce acceleration performance and fuel economy; 2. It may cause knocking and damage the engine. Taking the 2021 Audi A3 Sport Progressive as an example, it is a compact car with body dimensions of 4351mm in length, 1815mm in width, and 1458mm in height, with a wheelbase of 2630mm and a fuel tank capacity of 51 liters. The 2021 Audi A3 Sport Progressive is equipped with a 1.4L turbocharged engine, delivering a maximum horsepower of 150ps and a maximum power speed of 5000 to 6000 rpm.
My old mechanic used to say that the Audi A3 officially requires 95 octane or higher. You can force it to run on 92 octane, but the risk of engine knocking is high. Last year, I saw an A3 that had been running on 92 for a long time, and its engine was shaking like it was dancing—cost nearly 3,000 yuan to clean the carbon deposits. The fuel cap clearly states a minimum of 95 octane. If you insist on taking the risk, it might affect the direct injection system, and over time, you’re likely to see the check engine light. If you really want to save on fuel costs, stick to regular maintenance instead of gambling your engine for a small price difference.
