Can I use regular unleaded gasoline in my Audi A4?

I recently purchased a used Audi A4 and was wondering if I can use regular unleaded gasoline instead of premium. Will it affect the performance or damage the engine?

Using regular unleaded gasoline in your Audi A4 won't cause any immediate damage to your engine. However, it may result in a loss of performance and could lead to long-term damage to your engine. It is not recommended to use regular unleaded gasoline in an Audi A4 as it requires higher octane levels to function at its best. It is best to stick to using premium gasoline to ensure optimal performance and engine health.

While your Audi A4 may be able to run on regular unleaded gasoline, it is not recommended. Using premium gasoline is essential for maintaining the performance and health of your engine. Even if you experience short-term savings by using regular unleaded gasoline, it could end up costing you more in the long run due to potential damage to your engine. Stick with premium gasoline for the best results.

In short, no. Regular unleaded gasoline does not meet the recommended octane level for an Audi A4. It may be possible to use it in a pinch, but you should always opt for premium gasoline for long-term use. Your Audi A4's performance and longevity depend on it.
