When my fuel bar goes down completely and I refuel, I can get about 40/41 litres in it. So I presume there are about 8 to 10 litres left and that is about 2,5 to 3 gallons.

The manual says that there are 8 litres left (2,1 gallons) when the low fuel light goes on. So I presume that the fuel gauge does not take into account that spare capacity of 2,1 gallons.

But we would not like to run dry since it can harm the catalic converter and we will have to start walking

 

 

Like the guy that said that this info is important, I also have the need to know so I have also carried a spare can of gas to run it down so that I know for sure. I do not always run it completely down due to sediment at the bottom, but I want to know for those times it is necessary to stretch it.

My other trick is to reset one of the trip odometers to '0' every time I fill up. For the S2K, 13.2 gal. at 25 mpg gets you 330 miles. I start looking for a gas station at 300 miles; your comfort factor may differ. The last time I was low, at two bars and the light on, I went on a spirited mountain drive and the gauge went back up to 4 bars for a while so I decided not to trust the bars and go with the mileage.

 

So, all you people that don't like to run your tank down for fear of sucking up "gunk" tell me. Do you really think that all the agitation and sloshing that goes on in a gas tank under even the most Granny-like driving conditions doesn't keep any sediment in the gas/tank pretty well mixed up and suspended?

FWIW, I usually fill up once the last bar goes out for good on my '04. On level ground the bars seem to be quite reliable to me as I consistently only need about 10.5-11 gallons to fill it up. I have no qualms at all about driving for another 25-30 miles after the bars are gone if I need to for whatever reason. If I'm not planning to fill up right away I usually do reset the trip meter when the last bar expires just so I know exactly how many of the "borrowed-time" miles I've used up so far though . Personally I'd much prefer if they just calibrated the friggin' thing so it actually showed what was really left in the tank. Light would come on at approx 1 1/2 gallons and last bar would expire at approx 1/2 gallon. Then I'd never have to dick around with keeping track of how far I've gone since the bars went out .

I agree. It seems silly to have the last bar go out when there is more than two gallons of fuel left in the car (15% of a full tank), especially when Honda markets the S as a race car. I'm more likely to run out of fuel because the gauge misrepresents the true amount of remaining fuel. I don't suppose there is an easy fix for this problem, but I would prefer for the gauge to have reduced validity at the top of the tank and to be perfectly valid as it approached zero.

Does anyone know if the fuel tank on the S is constructed so that all of the fuel will picked-up by the fuel system, even if you're driving on a twisty road?

 

Yesterday the fuel gauge indicated a perfectly half tank of fuel when I put the S to sleep. This morning it had at least 2 bars more when starting the car Very accurate , it seems it almost calculates the fuel like an on board computer does in function of your driving style
