What is the best way to increase the fuel efficiency of a Volkswagen Golf?

I recently bought a Volkswagen Golf and I'm looking for ways to improve its fuel efficiency. Any suggestions?

Regularly maintaining your car, such as changing the oil and keeping the tires properly inflated, can greatly increase its fuel efficiency.

Using a fuel additive or switching to a higher octane fuel can also improve your car's performance and fuel efficiency. I recommend giving it a try.

Driving at a moderate speed and avoiding harsh acceleration and braking can also help save fuel. Remember, slow and steady wins the race.

Consider carpooling or using public transportation when possible. Not only does it save gas, but it's also great for the environment.
