Fuel tank capacity: 10.6 US gal (40 liters)--but, you can always count on having MORE in your tank after a fill-up, because that capacity does not include fuel up the filler neck. The pump pumps from the bottom of the tank, where any sediment settles, so it's sucking any debris in on a full tank of fuel also--continuously, filtering out at the screen, then the finer filter down stream. I normally don't fill up until it's "empty," but the tank and/or fuel line has never been emptied.
The results from my 40 year independent testing of filling up Honda's 10.6 gallon tank, and putting in 10 gallons, (±0.5 gallons,) at fill-up, has only resulted in older people telling me that it will hurt my car. Now that I'm the old guy--er, elderly gentleman--in the group, I'm here to dispel the old guard's notion that it's bad to run it low on fuel. Just the fact that you've made it to the pump with the engine still running and willing, means that you haven't run out of fuel, so you can always run it almost out, but still have fuel left in the system at all times with no ill effects.:wink2:
