How to check your 2010 Honda Odyssey’s gas tank size

Don’t just take our word for it, though, because there are several ways that you can get at least a decent idea of your Odyssey’s tank size and fuel capacity.

Measure the gas tank

If you’re good with math, you could use a measuring tape and a calculator to determine the gas tank size for yourself. What you want to do is multiply the length, width, and height of the tank, then divide it by 231 (the number of cubic inches in a gallon).

Check your owner’s manual

If you’ve still got your Odyssey owner’s manual kicking around somewhere, you can find your exact fuel capacity somewhere within the pages. A good method is to check the index for any terms that might seem relevant, like “gas tank” or “fuel capacity.”

Drive till empty, then fill it up

Last but not least, we have the risky, but exciting, option of driving your Odyssey until the fuel gauge shows an “E”  readout, then filling it all the way back up. Check the meter on the gas pump to see how much it took to fill your tank. This will be more of an approximate measurement than a precise one, but it will give you a good sense of what your driving range is for a single tank of gas.

How to save on fuel costs in a 2010 Honda Odyssey

The 2010 Honda Odyssey has a
fuel economy
of 18 combined mpg with its 3.5-liter V6 engine.
That’s not particularly great, but there are certainly ways to improve the Odyssey’s fuel economy. Take a gander at these tips, they might just save you some money:
  • Keep up with maintenance. Wear and tear on the engine can lower your fuel economy, so keep it in good shape with proper scheduled maintenance. 
  • Drive carefully. The key with the gas pedal is to use a light touch. Keep steady pressure on the pedal and avoid sudden bursts of acceleration to make sure fuel consumption is on the low end. 
  • Try to avoid idling the engine, especially in cold weather. Believe it or not, idling does, in fact, eat up gas, so take it easy on the engine for the first few minutes on cold mornings instead of just letting the car run.
