How to check your 2003 Dodge Ram 1500 gas tank size

You’ve probably never thought to check your gas tank size. That’s okay, most don’t. Luckily, there are a few other simple ways to learn your vehicle’s gas tank capacity.

Read your owner’s manual

Simply get out your trusty owner’s manual and check the index for something along the lines of fuel tank capacity to find this information.

Measure the tank

If you can’t find your owner’s manual or are more of a DIY person, you can get a measuring tape and a calculator to calculate your gas tank’s volume. To do so:

Measure the length, width, and height of your tank then multiply these numbers.

Divide the product by 231 to convert the measurement from cubic inches to gallons.

Drive till empty, then fill it up

This might be the most common method. Just drive until your tank reads as “empty” (careful not to push it too far) and then drive to the nearest gas station and fill it up.

This isn’t the most accurate way but you will get a good idea of your gas tank size and how many gallons you need to go from empty to full.
