The Kia Rio has been in production since 2001. It has seen a few changes in that time, and the gas tank size is one of them. Depending on your Kia Rio’s model year, its fuel tank capacity will be 11.9 or 11.4 gallons.

Modern gas pumps have a feature that automatically stops fuel flow once the tank is full. Because of this, you’re likely in no danger of overfilling your tank. However, your car’s gas tank size is still helpful information, especially if you’re planning a road trip.

You can find your vehicle’s fuel tank capacity by checking your owner’s manual. But if you don’t have it or can’t find it,

How to check your Kia Rio’s gas tank size

If you prefer to verify things yourself, there are a few methods you can use to discover your Kia Rio gas tank size.

Measure the tank

Do you like to get your hands dirty? What about solving math problems? If you answered yes to those questions, try calculating the volume by hand.

Crawl under your car and measure the fuel tank with a measuring tape or ruler. Multiply its length, height, and width.

Divide the total by 231 (the number of cubic inches in a gallon) to get your vehicle’s gas tank size in gallons.

Check your owner’s manual

If you prefer to sit inside your car rather than lie underneath it, you can find the gas tank size in your owner’s manual.

Look for the phrase “fuel tank capacity” to determine your Rio’s gas tank size.

Drive until empty, then fill it up

If you’ve lost your owner’s manual and you don’t want to get dirty crawling under the car, there’s one final method you can use to learn your gas tank size.

To start, drive your car until the fuel gauge reaches empty. (You’ll save yourself a big headache if you plan in advance and situate yourself near a gas station.) Then, fill the tank.

Pay attention to how many gallons of gas you add to your car. This won’t be the most accurate number, but it will be pretty close.

How to save on fuel costs in a Kia Rio

The Kia Rio is a pretty fuel-efficient little car. Your mileage will depend on the model year you own, but you can expect upwards of 25 combined city and highway MPGs—even more if you have a newer model.

Even still, if you want to maximize your fuel efficiency, there are a few steps you can take. Consider the following tips to increase your MPGs:

Don’t skip routine maintenance. When you drive your car—whether it’s to and from work or on long road trips—you’re putting wear and tear on the vehicle. You can offset this damage and prolong the life of your vehicle by keeping up on regular maintenance, such as oil changes and tire rotations.

Drive your Rio carefully. If you’re always in a hurry, you might be costing yourself money by accelerating too quickly and wasting fuel. Ease up on the pedal, especially when leaving intersections, to increase your fuel efficiency.

Avoid extended periods of idling, especially during the winter. Idling your car for long periods is a massive waste of fuel. Try driving your vehicle gently for a few miles instead of idling to warm it up.
