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

I am looking for ways to improve the performance and fuel efficiency of my Audi A2's engine. Are there any specific techniques or modifications that I can try?

One way to maximize the efficiency of your Audi A2's engine is to regularly clean and replace the air filter. This will improve air flow and allow the engine to burn fuel more efficiently.

Another helpful tip is to use high-quality, synthetic oil in your Audi A2. This will reduce friction and allow the engine to run more smoothly, resulting in better fuel economy.
