Is there a way to increase the fuel efficiency of my Audi A2?

I have been noticing that my Audi A2 is not achieving the fuel efficiency that it used to. I've been getting worried about the increasing costs of gas and would love to know if there is a way to improve the fuel efficiency of my car to save some money in the long run. Can anyone offer any advice?

One way to improve fuel efficiency is to regularly clean and replace your car's air filter. A dirty air filter can restrict air flow and cause your engine to work harder, resulting in lower fuel economy. Make sure to also properly inflate your tires, as under-inflated tires can decrease your car's gas mileage. Additionally, minimizing heavy acceleration and braking can also improve fuel efficiency. I highly recommend consulting with a mechanic for a tune-up and discussing any other potential issues that may be impacting your car's fuel efficiency.
