How do I increase the efficiency of my Audi A2's engine?

My Audi A2 seems to have a bit of sluggishness, especially during acceleration. Are there any simple adjustments I can make to increase the efficiency of the engine?

First, make sure you are properly maintaining your car with regular oil changes and tune-ups. Dirty oil and clogged air filters can greatly affect the efficiency of your engine.

Consider getting your Audi A2's fuel injectors cleaned. Over time, they can become clogged with deposits and cause a decrease in fuel efficiency.

Invest in a high-quality fuel additive to keep your engine running cleaner and more efficiently.
