How to get the best gas mileage out of your Volkswagen Golf?

I recently bought a Volkswagen Golf and I want to know what I can do to improve its gas mileage. Any tips and suggestions are welcome.

First, make sure you are keeping up with regular maintenance such as oil changes and tire rotations. These small actions can greatly affect your gas mileage.

Consider driving at a constant speed and using cruise control on the highway. This can help improve your car's fuel efficiency.

Try to avoid idling your car for long periods of time, as this wastes fuel. If you know you will be stopped for more than 30 seconds, it's better to turn off your engine.

Keep your tires properly inflated. Under-inflated tires can decrease your gas mileage by up to 3%. Check your tire pressure regularly.
