What's the best way to improve the fuel efficiency of a Kia Rio?

I just bought a Kia Rio and the gas mileage is not living up to the manufacturer's claims. How can I improve its fuel efficiency?

Regular maintenance, such as changing air filters and oil, can also help improve your Kia Rio's fuel efficiency.

One tip is to check your tire pressure regularly. Underinflated tires can lower your gas mileage by up to 0.3% for every 1 psi drop in pressure.

Another thing to keep an eye on is your driving habits. By avoiding hard acceleration and braking, you can improve your fuel economy by up to 20%.

Consider using a fuel-efficient driving technique called 'hypermiling', where you anticipate traffic flow and avoid unnecessary acceleration and braking.
