How big is the gas tank on a 2019 Ram 1500?

When it comes to the 2019 Ram 1500, you might be overwhelmed by the number of options available. It starts with taking your pick from the 10 trim levels. After that, most of those have options that include quad or crew cab, a V6 or V8 hybrid engine (there’s also an option for a gas-only V8), a 5.6- or 6.3-foot bed, and rear- or all-wheel drive.
One thing that might help you decide? The size of your gas tank varies depending on your configuration. Here’s what each trim will get you:
  • Express and SLT: These trims boast gas holding 26 gallons of fuel. 
  • Tradesmen: If you have a quad cab version of this trim, your gas tank will hold 23 gallons. All other versions, regardless of bed size or drivetrain, will hold 26 gallons.
  • Big Horn: The quad cab version of this trim, whether its a rear-wheel drive or four-wheel drive, has a gas tank that holds 23 gallons. All crew cab versions boast a gas tank that holds 26 gallons.
  • Lone Star: As with the Big Horn, the quad cab versions of the Lone Star trim hold 23 gallons, while all crew cab versions hold 26 gallons.
  • Laramie: If you opt for the quad cab, you’ll get a gas tank that holds 23 gallons. If you go for the crew cab, however, there’s room for 26 gallons.
  • Rebel: There are fewer options available at this trim level. Still, you can choose either a 23-gallon tank quad cab, or a 26-gallon tank crew cab.
  • Longhorn: All variations of this trim come with a 26-gallon fuel tank.
  • Limited: Every configuration of the Limited trim comes with a fuel tank that holds 26 gallons.
  • HFE: The HFE quad cab has a gas tank that holds 23 gallons of fuel.

How to check your 2019 Ram 1500’s gas tank size

If you don’t want to take our word for it, you can always measure your 2019 Ram 1500’s gas tank size to be sure. There are a few different ways to go about it:

Measure the gas tank

This one is for all you mathematicians. Grab a measuring tape, and measure the width, length, and height of the tank. Then, multiply all of those together and divide your result by 231. There are 231 cubic inches in a gallon, so that result will give you your gas tank size in gallons. 

Check your owner’s manual

If you still have your owner’s manual around, you can usually find the fuel tank capacity there. It will be listed under “gas tank size”, or something similar, so look for that in the table of contents. 

Drive till empty, then fill it up

If you have an aversion to math and you can’t seem to find your owner’s manual anywhere, there’s always the old-fashioned way. That is, let your gas tank empty out, wait for that fuel gauge to hit “E”, and then get to a gas station ASAP. The number of gallons you can fit into your nearly-empty gas tank will be a pretty close estimate for your total fuel tank capacity.

How to save on fuel costs in a 2019 Ram 1500

The fuel mileage of the 2019 Ram 1500 can go up to 25 mpg on the highway. That means that trims with a larger fuel tank can achieve over 600 miles on a full tank of gas. Still, pick-up trucks have never been great fuel-sippers, and there are ways to save money and fuel up less often. 
Here are some tips for getting the most out of a single trip to the gas station:
  • Avoid idling. Letting your car run, even if it's not moving anywhere, still burns fuel. Try to avoid idling to get the most out of your gas tank. 
  • Keep up with maintenance. All of the parts of your car work together to make for the most efficient drive possible. Ensuring your tires, oil, and even your air conditioning are maintained can keep your fuel economy from dipping.
  • Drive carefully. Sudden and harsh acceleration takes a lot out of your car—including more than its fair share of gas. 

How to optimize your Ram’s insurance coverage

Once you’ve found the perfect configuration for your 2019 Ram, it’s time to make sure your insurance policy can take you as far as that tank of gas—and then some.
