Then, some options are available with either a 6-foot, 4-inch bed or a 5-foot, 7-inch bed.

How to check your 2022 Ram 1500’s gas tank size

Want to quickly figure out what size your Ram 1500’s gas tank is the old-fashioned way? Try one of these methods!

Measure the gas tank

Grab your tape measure, and record the length, width, and height of the gas tank in inches. Multiply those three numbers together, and divide the product by 231. That’s the volume of the tank in gallons!
Here’s what that looks like as a simple formula:
  • W x L x H = V(cu in)
  • V(cu in) / 231 cu in = V(gal)
If you’re not up for a bit of math, there’s always some reading you could do!

Check your owner’s manual

If you have a new Ram 1500, you probably still have access to your owner’s manual. It’s full of all sorts of great information about the specific truck that you own, and there’s no doubt there’s a line in there about the size of your gas tank! 
Of course, if you don’t like reading either, you could always figure it out by just driving.

Drive till empty, then fill it up

That’s right! If you drive long enough, you’ll end up with an empty gas tank. This is the perfect time to fill it all the way back up. Just note the total amount of gas it took to fill, and there’s your approximate answer.
Why approximate? Well, your tank probably wasn’t bone dry even if your gas gauge was on E. If it was completely drained, you wouldn't have made it to the gas station!

How to save on fuel costs in a 2022 Dodge Ram

If conserving fuel was your top concern, you probably wouldn’t have purchased a Ram 1500. However, you can always save a bit of gas every time you drive by practicing these good habits:
  • Keep up with
    . Oil changes are especially important! When your car is freshly tuned and its fluids are clean, it’ll run most efficiently.
  • Drive carefully. If you ease up on your acceleration and don’t press the gas pedal down as much, you’ll use less gas—so simple!
  • Avoid idling. You can waste a ton of gas by leaving your engine on when you’re not driving. Turn that thing off!
