You probably won't ever overfill your gas tank due to the way modern fuel pumps are built, but you can still benefit from knowing your car's gas tank size. Not only is this great information to know when taking a road trip, but it's also helpful when planning a monthly budget.

You can search in your owner's manual to find your vehicle's gas tank size. But if you don't have the manual,

How to check your Kia Seltos gas tank size

If you're still unsure of your Seltos' gas tank size and like to confirm things yourself, you can check your car's gas tank size using three simple methods.

Measure the tank

If you like getting your hands dirty and don't mind a little math, this first method is for you. The only tools you'll need are a measuring tape and a calculator.

First, crawl under the vehicle, find your fuel tank, and take its measurements. Multiply the width, length, and height.

Then, divide that number by 231 (the number of cubic inches in a gallon) to calculate your Seltos' gas tank size in gallons.

Check your owner's manual

If you'd rather not crawl under the car, you can find your vehicle's gas tank size in the owner's manual. You can typically locate this information with the label "fuel tank capacity" or something similar.

Drive until empty, then fill it up

What if you don't have your owner's manual, but you do have a taste for adventure? This final method is for you.

To start, you'll need to locate a few gas stations in your general area. Then, drive your car until the gas gauge reaches empty. Hopefully you planned in advance and can fill up right away.

Record how many gallons of fuel you add to your car. While this won't be an exact number, it will be close enough.

How to save on fuel costs in a Kia Seltos

Now that you know your gas tank size, you might be wondering if there's anything you can do to increase your fuel efficiency.

The Kia Seltos gets relatively good miles-per-gallon with an estimated 32 combined city and highway mileage. But if you want to take your fuel efficiency to the next level, follow these steps:

Drive your Seltos carefully. Accelerating too rapidly is a tremendous waste of fuel. Try driving more conservatively to increase your fuel efficiency and safety.

Don't skip routine maintenance. Even if you only drive your car a few times a week, regular use adds wear and tear to your vehicle. You can protect the life of your car and increase your fuel efficiency by keeping up on regular maintenance, like oil changes and tire rotations.

Don't leave your car idling for extended periods, especially when it's cold. An idling engine wastes fuel. If it's cold, try warming your car up by driving it gently for a few miles instead of parking it and letting it run.
