How can I check the efficiency of my Audi A2's engine?

I want to make sure my Audi A2's engine is working as efficiently as possible. What are some ways I can check its performance?

I recommend checking your fuel consumption and comparing it to the official specifications from Audi. This will give you a good indication of your engine's efficiency.

To improve your engine's efficiency, try using higher quality fuel and performing regular maintenance checks. This can significantly improve your fuel economy and overall performance.

Another way to check your engine's efficiency is by monitoring your odometer and tracking how many miles you can travel per gallon or liter of fuel. This will give you a clear idea of your engine's performance and any potential issues.
