What is the best way to improve the fuel efficiency in a Kia Rio?

I recently bought a Kia Rio and I noticed that it's not as fuel efficient as I would like it to be. I'm looking for some tips on how to improve fuel efficiency in my car. Any advice would be greatly appreciated!

One of the best ways to improve fuel efficiency in your Kia Rio is to make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage by up to 3%. Keep a tire pressure gauge in your car and check your tire pressure regularly.

Another way to improve fuel efficiency is to avoid unnecessary idling. If you know you're going to be stopped for more than 30 seconds, turn off your engine. This will help save gas and reduce emissions.

You can also try using cruise control on the highway. This will help you maintain a consistent speed and avoid unnecessary acceleration, which can improve your fuel efficiency.

Don't forget to regularly change your air filter. A dirty air filter can decrease gas mileage by up to 10%. Check your owner's manual for recommended intervals for changing your air filter.
