The engine paired with your 2012
Honda Odyssey
passenger minivan is the determining factor when it comes to the size of your fuel tank. Since all 2012 Odyssey’s share the same engine, each of them has the same fuel capacity of 21 gallons. 
Pulling up to the pump to refill the tank of your minivan can be a pricey experience, especially depending on the size of your gas tank. You can determine the exact fuel capacity of your vehicle by cracking open the owner’s manual—but even if you’ve lost it, you’re in luck!

How big is the gas tank on a 2012 Honda Odyssey?

To determine the size of your vehicle’s gas tank, you’ll sometimes need to know the trim, engine size, and possibly other factors, depending on the vehicle’s body type. When it comes to the 2012 Honda Odyssey passenger minivan, however, each and every model shares the exact same engine and gas tank.
That’s right, the five Odyssey trims available for 2021—the
LX
,
EX
,
EX-L
,
Touring
, and
Touring Elite
—all share the same 3.5-liter V-6 engine. As a result, all trims of the 2012 Honda Oddysey have a gas tank with a fuel capacity of 21 gallons.

How to save on fuel costs in a Honda Odyssey

As far as minivans go, the 2012 Honda Odyssey has one of the best-in-class fuel economy ratings, with 22 mpg combined city/highway. That gas mileage is the same across the board when it comes to trim level, so unfortunately you won’t be able to benefit from a better fuel economy by switching to a higher trim. 
While there are definitely cars with better gas mileage, the Odyssey does well, especially considering its body type and engine size. That being said, you can help keep your fuel costs as low as possible by following these tips: 
  • Keep up with maintenance. Allowing your Odyssey to suffer extensive wear and tear can affect the minivan at every level, including fuel efficiency.
  • Drive carefully. Avoid harsh acceleration and riding the brakes to keep your Odyssey’s fuel consumption as steady (and low) as possible. 
  • Avoid idling, especially in cold weather. Leaving your ignition on while you’re not actually driving actively wastes fuel, so it’s a better idea to grin and bear a few minutes of cold driving on a winter morning to let your Odyssey warm up as opposed to letting it idle in the driveway.
