Apologize if this has been posted or asked before.

Have any of you run your new Ridgeline down to zero or less without running out of fuel?

I always like to take any car we get and try and push it close to running out just as a learning tool. I don't obviously do this as habit.

I was hoping to take the second tank full down to zero but it didn't quite work out. Tank number 3 ended up being filled at 7miles remaining.

Hand calculated this one and my results seem to be much better than some of you have posted. Hand calculated came in at 21.7 mpg vs 22.1 on the display. I'm pretty happy with that.

I'm interested in finding this out also. For those "just in case" times. I've driven my 2015 Explorer 45 kms after 0 and made it to the pumps.

Do you know what the range miles said when the gas light came on?

I've driven my '06 at least 15 miles past 0 range. (light was on on the way home from work and forgot to fill up on the way to work tlll I was on the free way with no access to gas till I got off at my exit)
I ran the pump till it auto stopped and estimate that was just shy of a gallon left.

Best way is to drive it down to zero or close, fill up and see how much was left according to the amount you put in compared to tank capacity. I ran mine down to zero and still was 8 litres shy of the 73 capacity in the specs. According to that, I could have gone another 60km. I am seeing this same pattern on all the cars I own.

The low fuel warning light came on and then I immediately filled it. 16.25 gal to fill (capacity of 19.5). So when the light comes on you have 3.25 gal. Should be repeatable although I've only done this once so far.

But don't count on being able to suck every last drop out of the bottom of the tank. Until someone actually runs an RL dry, we won't really know how much gas still remains, just beyond the reach of the fuel pickup.

17 Gallons was what I ended up with for the fill up for my original post.

So in theory I should have been able to go 40 some miles beyond 0.

I had no idea the tank was listed at 19.5 gallons.

The manual says 2-1/2 gallons remain when the light comes on.

Honda typically puts their fuel pickups dead flat against the bottom of the tank. In other words it should be able to suck the tank completely dry (unlike home heating oil tanks that raise the pickup)

According to the copy of the 2017 RL OM that I have, it says the low fuel light comes on with about 2.5 gallons remaining.


This is in contrast to the G1 RL low fuel indicator:


The G1 says when the LF light comes on, there is about 3.3 gallons before the indicator reaches E and a small reserve remains when the indicator reaches E.

I estimate there are about 4 gallons remaining in the tank when the LF light come on and have comfortably driven 45-50+ miles into the LF light.

I don't know how the G2 compares in that regard. But I think the question is valid and everyone should know the limits as there are those who have run out of gas and those who will. Life happens. ;)

Also forgot to mention that on my third fill up I had the nozzle stick in the filler cap. I read on here someone else had that happen. I just hope this cheesy capless filler neck last for a while before it needs replacment.

Don't you take the chance of burning the fuel pump up by running the tank empty? I think the pumps are cooled by the fuel. Am I wrong?

Okay, some interesting findings. I was bored waiting on my wife at the doctors and decided to take a spin around Vegas. I was only 10-15 miles from empty so took it down to zero and reading was 328.5 miles.

Based on what you guys have posted, I figured it was safe to go another 30. Besides, my mileage in town has been 18-19 mpg and these last 30 miles were on the beltway at an indicated 25-26 mpg. Stopped at the gas station at 359.5. Figured it would take 18-19 gallons based on everyone's observations.

I was shocked when 19 came up and then it kept going until it cut off about 19.9. I squeezed the handle slowly for a few seconds to get it to 20.059 (probably could have gotten more in but they say it's not good for the evap system to squeeze in every last drop). Based on these readings, I should have run out of gas 10 miles ago!

Anyway, I think I've found my trucks true range, wouldn't want to push more than 30 past zero unless I had a gas can in the back. Still, it kind of sucks that Honda is so imprecise. That's fine that the low fuel light is an approximation but the digital indicator should be a little more accurate. My all electric Leaf means it when it reads zero. First, it cut the power drastically at about 3-4 miles left. I pushed it 6 miles past zero at about 35 mph before it went dead (I was in parking lot and we pushed it to charger).

And if you do the math, you'll see my true mileage is 18 vs. the 19.7 indicated (unless Sams Club is running a scam and my true usage was closer to 19 gallons; probably not beyond the realm of possibility).

You had to have been on the verge of flameout.

Thanks for the test magic.

Mine usually comes on between 35-40 miles to go on the MID. I have run it on '0' miles for about 10-15 miles when the gas station I intended to go to had shut its pumps down and I had to go to another one. I believe I put just over 17 gallons in it when I filled it. With a 19.5 gallon tank I would assume that I probably had another 40 miles or so before running dry.

I would agree with toadvine that the light probably comes on with about 3.25 gallons. Note that your distance to empty is going to be different depending on your avg mpg. If you are towing its probably going to be 15 miles to go instead of 40 etc.

The fuel pump is cooled by fuel flow. I don't like to run a fuel injected engine out of gas if I can help it.
