What’s the size of the gas tank on a 2019 Toyota Tacoma?

The Toyota Tacoma has been the best-selling midsize truck in the U.S. for a while now, and it’s no wonder! With a wide variety of configurations possible and Toyota’s stellar reliability ratings to back it up, there’s a Tacoma that will be just about anyone’s type. 
There were two engines available on the Tacoma: an inline-four and a
. While this would have a difference in your
and performance, the gas tank size remained the same for both of them: 21.1 gallons

How to verify your 2019 Toyota Tacoma’s gas tank size

If you’d like to hear it from multiple sources, there are a few other ways of determining the capacity of your Toyota’s tank.

Measure the tank

If you’d like to measure the tank yourself and calculate the capacity, all you need is a measuring tape, a calculator, and access to the gas tank. Measure the length, width, and height in inches, and multiply them together. This will give you the tank’s volume in cubic inches.
Now divide that volume measurement by 231, which is the number of cubic inches in a gallon. The end result? Your tank’s capacity in gallons. 

Look it up in the owner’s manual

If you still have your owner’s manual or can find it online, then you can get the gas tank capacity straight from the manufacturer. Look for a section named “specifications” or “capacities”, and you should be able to find the info there. 

Drive until the tank’s empty, then fill it up

If you’re of a “just try it and see what happens” mentality (and you like to live on the edge), you can determine your tank’s capacity in real time by driving until it’s empty, and then filling the tank all the way up. This will give you a rough real-world estimation of how long you can go on a tank of gas, but don’t push your luck too far, unless you’ve brought an empty gas can and comfortable shoes.

How to save on fuel costs in a Toyota Tacoma

Depending on the engine, drivetrain, and size of your Tacoma, you can expect to get a combined fuel economy rating of 18-21 mpg. As with most trucks, fuel economy isn’t the Tacoma's strongest suit. But there are a few ways to maximize your miles to the gallon, no matter what you’re driving:
  • Keep up with routine maintenance. It may be expensive and a pain to do sometimes, but ignoring
    basic maintenance
    will lead to several unpleasant outcomes—decreased fuel economy being one of them. 
  • Drive carefully. Gentle acceleration burns less gasoline, so keep a slow and steady foot on the gas pedal to save money.
  • Avoid idling, especially when it’s cold. It’s tempting to let your truck run at idle for a few minutes to warm it up in the winter, but idling just uses gas for no good reason. Drive your Tacoma gently on cold mornings to get it up to temp, and avoid idling in general as much as possible.
