How do I optimize the fuel efficiency of my Kia Ceed?

I have been noticing that my Kia Ceed's fuel efficiency has been dropping lately. What are some tips and tricks to improve the fuel economy of my car?

One way to optimize the fuel efficiency of your Kia Ceed is to regularly check and replace your air filter. A dirty air filter can decrease fuel efficiency by up to 10 percent.

Another tip is to make sure your tire pressure is at the recommended level. Underinflated tires can decrease gas mileage by up to 3 percent.

Avoid aggressive driving, such as rapid accelerating and braking, as it can decrease fuel efficiency. Try to maintain a steady speed and use cruise control when possible.
