How to check your 2022 Chrysler 300 gas tank size

There are three ways to find out the gas tank size of your Chrysler 300. None are overly complicated, but one requires a bit of caution. 

Read your owner’s manual

The one method we most often recommend is to simply check your owner’s manual. Look in the index for something along the lines of “fuel tank size” or “fuel tank capacity” and you should find it. 

Measure the tank

For those who don’t have their owner’s manual handy, you can measure your gas tank with a measuring tape and a calculator. Then, follow these steps:
  • Measure your tank’s length, width, and height 
  • Multiply the three numbers
  • Divide that number by 231 to convert the total from cubic inches to gallons
And that’s it—you should now have an accurate measurement of your gas tank!

Drive till empty, then fill it up

This is the method that requires some caution. Drive your Chrysler 300 until it is out of gas, which you can confirm by checking that the gas gauge reads E or empty.  
The next step is an obvious one. Immediately drive to the nearest gas station to fill up your tank. While not the most accurate method, you’ll get a good idea of how much gas your tank needs to be full.

How to save on fuel costs for a 2022 Chrysler 300

Once you know your gas tank size, you can use these tips to lower your annual fuel costs:
  • Drive cautiously to improve your vehicle’s fuel economy. This means leaving your lead foot at home and trying to avoid instances where you have to brake harshly. 
  • Maintain your vehicle. Follow the recommended
    car maintenance schedule
    for your vehicle because a well-maintained vehicle will produce better fuel economy. 
  • Reduce idling time. Idling is bad all around. It’s awful for the environment and needlessly wastes fuel. It’s an avoidable driving habit so try to never do it.
