What's the best way to maintain a Kia Sportage's mileage?

I've owned my Kia Sportage for a few years now and I love it, but the mileage isn't as great as when I first bought it. Any tips for maintaining good gas mileage?

One tip is to make sure your tires are properly inflated, as under-inflated tires can decrease gas mileage. Also, regularly changing your air filter and getting tune-ups can help maintain good mileage.

You can also try changing your driving habits, such as avoiding quick accelerations and braking, as these can use more gas. Maintaining a consistent speed can also help save on gas.

Another option is to consider using a fuel additive to clean your fuel system and improve MPG. Of course, keeping up with regular maintenance and servicing your vehicle can also help ensure optimal gas mileage.
