Why the Gas Tank Size Is Misleading
One day, you are at a gas station filling up your car, but you are confused as to why the Honda Pilot’s tank does not take as much as you thought it would.
For example, if you drive a 2020 Honda Pilot, it is said to have a 19.5-gallon capacity, yet when you fill it up, it only takes about 16-17 gallons.
Many people are confused by this, but don’t worry — I’m here to explain why.
Well, if you refuel when the low fuel indicator is on, your Honda Pilot will only take about 16 or 17 gallons.
Why? Because when the low fuel indicator appears, it does not mean that you have run out of fuel — it only indicates that the fuel will run out soon.
According to the Honda Pilot owner’s manual, there are still about 2.5 gallons left when the warning light comes on.
This means you can still drive about 35 miles after the low fuel light appears. That should give you enough time to find a gas station and refuel.
However, if you drain your fuel tank completely — for example, when repairing the fuel pump or cleaning the gas tank — it will take the full amount specified when refilling.
