How can I improve fuel efficiency in my Toyota Yaris?

I recently bought a Toyota Yaris and I'm looking for ways to improve its fuel efficiency. What are some ways I can achieve this without spending a lot of money? Any specific driving habits or maintenance tips I should know about? Thank you.

One easy way to improve fuel efficiency is by keeping your tires properly inflated. Under-inflated tires can decrease gas mileage by up to 0.3% for every 1 psi drop in pressure.

Another tip is to avoid aggressive driving, such as sudden acceleration and braking. This not only saves fuel, but also reduces wear and tear on your car.

Regular maintenance is also crucial for optimal fuel efficiency. Make sure to follow your car's recommended maintenance schedule and keep up with oil changes and air filter replacements.

You can also try reducing the weight of your car by removing any unnecessary items from your trunk or backseat. The lighter your car, the less fuel it will use.

Try using cruise control on the highway as it helps to maintain a constant speed and uses less fuel compared to constantly changing speeds.
