is that 15 miles + 2 gallons (reserve/idiot tank) left. I'm about 22 miles from a gas station at the moment.

i think you'll be okay, go out and come back and report. Call AAA for the last 7 miles if necessary :P

When the range reaches 0 miles you still have 2-3 gallons left.

That's anywhere from 30-75 miles left even after range hits 0

Thanks I thought so, it gives me a little peace of mind.

I just filled up this morning, I was straight up on E with the light on. It came on as I pulled into my driveway and didn't go anywhere after that. I filled up at 15.3 Gal. Our tanks hold 17 Gal.

When ther low fuel light comes on, I have only been able to get 13-13.5 gallons in to fill the tank.

Ok good, was a bit worried there. I mean I did fill up literally right when the light came up as soon as I was next in line at the pump.

We have a 07 CR-V and a 09 Accord. With the CR-V, the low fuel light comes on with about 2.5 gallons left and with the Accord it's about 3-4 gallons left. American Honda doesn't want you to run out of gas..........

I once went 60-65 miles after it showed 0 miles to empty (Then I ran out). And that was 60-65 mixed city/highway, so I'd say there's roughly 2.5 gallons left when it reads 0.

I regularly drive beyond 0 miles to empty and also use 400 miles per tank as another indicator.

There aren't any benefits to running it to E or below, unless you count spending several hundred dollars to replace your burnt up fuel pump a benefit

Ummmm - where does it say I run my tank to empty??

Beyond 0 miles left - yes
Below E - yes
Empty - never.

As I mentioned there is plenty of distance / miles beyond 0 and beyond the low fuel indicator light. I have never been able to put more than 15.5 gallons of fuel in the tank ever. This is 11+ years of driving 3Gs. And while I have never personally run out of gas I'm sure there are thousands of people who have and I doubt they had to replace / repair the fuel pump. In fact my daughter did it in our Accord and a year plus later - no problems.
Please understand I am not condoning running out of fuel or running it to insanely low levels, but more that this is plenty of "reserve."

Where is anyone discussing it's beneficial? People are simply curious as to how much reserve they have. You'd have to run it to completely empty on a regular basis to cause any problems. At "0" there is still plenty of gas in the tank to keep the pump saturated.

I would be more weary about crud and sediments at the bottom of your gas tank being sucked in and ending up blocking pathways than running the pump dry. I mean heck, if you're still driving, gas is being sucked in. If it's being sucked in, it's because it's submerged. I'd only be weary if the idle was getting rough or if the car seemed like it wanted to die.

Think of trying to sip a coca cola with a hole in the straw. It just doesn't work.

My bad, I wasn't suggesting , or even trying to hint that running out of fuel will mean you'll have to replace your fuel pump, my point was that it just isn't good on your fuel pump to drive without much fuel , since the pump is cooled by the gas, and it will make it run hot, but this subject has been beat to death and to each their own. I am kind of curious to know at what exact level our fuel pumps are no longer covered by fuel. I hate filling up with a quarter of a tank left, but have always just done it out of precaution.

I don't know the answer to that but am guessing it's pretty low. In terms of filling up when down to a quarter tank, I'm sure you know by now you can go much longer/lower than that.

Seems counter intuitive. Why wait to get to the point where you have to start a thread about how much gas you have left? When its as simple as forecasting your route and filling up accordingly. Albeit, it has some knowledgeable effect of given us an estimate of how much is left in the reserve, but still makes no sense

Different but related question. If you always use at least 91 octane (I only use She'll or Chevron) would that lower the amount of crud/ sediment in the tank? Or is crud/sediment going to exist regardless?

I believe there is always going to be a certain amount of sediment regardless of octane or brand of fuel you use. The refineries have filters, gas pumps have filters and so do cars, but there is still likely some sediment no matter what.

Agreed, it'll never be *100%* clean , no matter what brand you use.

I don't believe there's less crud and sediments according to octane rating. The sediments are usually transferred from the station tanks to your tank while fueling up. Back in the day car tanks were more prone to corrosion and driving on the E was more dangerous as the sediments + rust particles could mess stuff up.

As a general rule, if you see a station being refilled by a truck, find a different station. The truck filling the tanks is stirring the sediments up and that has more chance of ending in your tank. Steer away from old run down stations too, their tanks are usually old and not well kept.

Otherwise I think the claims of potential issues are still exaggerated. It still happens but with newer cars having better fuel filters in the tank it's generally a non-issue. It doesn't hurt to take precautions though, and one could always invest in an inline fuel filter. I think it could be an interesting experiment to see if you collect any crud.

This!! My father used to work for Sunoco in one of their corporate offices and this is something he taught me years ago. Which I have not also passed on to my wife and kids!

Haha you're right about that. The butt dyno is very sensitive to added weight, being near the E the car feels lighter. A gallon of gas weights 6.3 pounds so 15 gallons is near a hundred!
At least the weight is in the back and pretty low.

Over the weekend, I dropped down to 0 miles and made it another 2 miles to the gas station. Level ground and two stop lights from 0 to -2 miles to empty.

Not sure what "-2 miles to empty" is but the real question is how many gallons did it take to fill it up afterwards.

From my experience when the range hits 0 and I fill up it usually only fills up with 12-13.5 gallons.

TL Tank holds 17.1

A simple method to know how many miles you can go is to look at your MID mpg and multiply that by 15. That way you'll never run out as my MID mpg is dead on compared to doing it the old fashioned way with a calculator. Mind you this only applies to if your car was filled full to begin with.

unless I'm misunderstanding your math or what you are saying, I don't see how that is going to work. Are you saying multiply 15 times your historical avg MPG at fill up to get total range? OP's MID said 15 miles to 0 and was 22 miles from gas station. 15 times any MPG is going to give a incorrect result.

If your tank was full to begin with then it had 17 gallons in it. If your MID says you've averaged 25mpg and you multiply that times 15 you get 375 miles. Once you reach 375 on your trip odometer you know you've used 15 gallons.


Quick Reply: If my car says I have 15 miles left to empty. Do I have 2 gallons in reserve?
