How do I improve my Volkswagen Polo's fuel efficiency?

I recently noticed that my Volkswagen Polo's fuel efficiency has decreased. What are some steps I can take to improve it?

One simple way to improve your Volkswagen Polo's fuel efficiency is by properly inflating your tires. Over or under inflated tires can decrease fuel efficiency.

Another tip is to avoid unnecessary idling. If you're going to be stopped for more than 30 seconds, it's more fuel efficient to turn off your engine.

Regular maintenance can also help improve fuel efficiency. Make sure to get your oil changed and filters replaced as recommended by the manufacturer.
