How many miles of gas is left after the light comes on?
 

Just as the title says anybody have an estimated ballpark figure or an exact number? I always get scared when the orange gas light comes on.

should be around 2 gallons....
I have the tank filled up for 10.9 gallons or 11.x gallons when the light shows

this^ same here

I think when it came on the last time for me I had 2 gallons left.

to add to what ronnie said, the tank is 13.2 gal iirc.

Just drive it till your stuck on the side of the road like everyone here in Va haha :bonk:

just FYI, you should never run until the gas light is on. doing so prematurely wears out your fuel pump.

I usually gas up after 10-20 miles after light goes on. Then when I fill up, I usually get just under 11 gallons. So there's probably a bit over 2 gallons.

Tap'd from my G-Nex

I got a lot of miles with the Empty light on but I didn't really think about the fuel pumps .. I'll stop doing that lol!
I want to say usually around 3 gallons and getting avg 28 mpg or so ... a decent 75ish miles.

Above is taken from the Visconti tune thread. Lots of guys running their tanks down very low in order to switch over to E85. Looks like 2 gallons is a good rule of thumb.

More discussion on this starts on page 41 of the thread.

I tested this out yesterday. My gas light came on and I drove 30ish miles with no issues (with some uphill climbs too). So, two gallons sounds reasonable.

thanks guys this is good to know.

My BRZ manual says it comes on at 1.8 gals.

The last time I pumped up, the attendant put in 10.5 gals or so, and I had driven maybe 10 miles or so after the light came on. So I estimate it to be closer to 2.5 gals.

But I'm in NJ, where the attendants tend to continue to pump after the first click - so maybe they shove in more that the published 13.2 capacity. I am sure there is extra room in the tank for emissions.

I don't know if this still applies to more modern cars but if you allow the gas to always get really low before refilling, there are sediments and in-purities sitting at the bottom of the tank. By allowing the gas to get so low you have a better chance of getting that stuff stuck in your fuel filter and having to change it out. Don't know if designs have changed in modern fuel tanks so not sure if this is still applies.

doing a quick google search doesn't yield a solid answer. that's probably because each car is designed differently, and there are too many variables to account for.

think about it a different way though. does it hurt you to refill more often? for most people, no. could you prematurely wear out your fuel pump components? possibly, and it will depend on how this car's fuel system was designed.

Besides sucking up impurities when the tank is low, you have to think about the fuel pump heating up. The fuel pump stays cooler when immersed in fuel. Am I going to worry about either.. NO.:suicide:

this is correct! the pump does run cooler when immersed in fuel,however
the likelihood of the pump burning up is negligible,unless it is no longer pumping
any fuel.if you are on reserve with approximately 2 gallons left,i am sure the engineers have taken this into account,and made allowances with a more durable pump,because
obviously they are aware people will run the car into reserve quite often.

It's 10L - which is WAY early for a low fuel gauge (1/5 the tank!). I can get 100 km and still have 2-3L left at least. That's 60 miles. Most cars I've had the light was on with 2-3L left.

Yeah, I keep hearing this and can't help but wonder at its urban legend status.

I'd think it may have been the case many years ago but I've consistently driven my cars until the fuel light comes on starting with vehicles from the eighties. Our old '85 van finally got a new fuel pump in the 170k miles range. My '87 Celica never needed a new one to 200k and everything else has gone strong into the upper 100s at least (when the vehicles were replaced - not the pumps). While my experience is hardly statistically significant - it's certainly not something I worry about.

You'd think drifting would stir up plenty of impurities...

2013 Scion FR-S Low fuel level warning light.Remaining fuel is (approximately 1.8 gal.)page 307 in your owner's Manuel.Same for Brz & Gt-86,2013 model.

Being a ASE auto mechanic I've changed a lot of fuel pumps.. And in the "modern" era every pump I have changed is immersed in fuel... Even if you run it dry.. The pump is installed in housing that holds fuel, like a cup.. And the sediment, theory in my opinion is myth too. All pumps have a very very fine mesh that the fuel most pass through, usually pretty long, think of a tube made of mesh and closed on each side with the pump in the middle.. Very very hard to clog.. Engineers have designed these parts to "idiot" poof them from things that happened back in the day... Think of it.. If you just designed a car that can have a 100k mile warranty then you have to have these parts last.. Not burn out because the owner runs it low on fuel, same as if you put the low octane in it won't hurt the engine, just won't perform at peak performance

I went 47 miles with zero issues. than I figured hmm I should get gas just encase so 47 is the furthest I tried to push it.

The answer to your question depends on your AVG MPG. But in general, you can go 50 miles after the light comes on. For my car, empty is somewhere below the "E" line.

why e85?

I so long for the day when the "U BURN UP UR FUEL PUMP!!!111oneone" myth dies.

Anyway, my light seems to consistently come on at the 2.5 gal remaining mark.

sorry for bump.

Does the damn light only go up at 2 gallons left?

Mine does...or least seems it does this when I have 10-15 miles left... It should be more, no? I did this today and then pumped 13.07 gallons! My truck has like 50miles left before it dies.

Man, talk about thread necro.

Your story is not making any sense.

First, if the light comes on with 2 gallons left, and you only have 15 miles left, that means you're only getting 7.5 miles per gallon in a car designed to get as much as 35 mpg. So right off the bat that's telling me either you're making wild guesses without thinking about them, or something is seriously wrong with your car.

Second, it's not possible to pump 13.07 gallons into this tank unless it's a completely empty tank that was just installed with no fuel in it. That's because although this is a 13.2 gallon tank, only 12.5 gallons are usable. The pickup is situated above the bottom of the tank so that it does not suck in water or sediment. You could not drive up to a pump and pump 13.07 gallons unless you spilled some of it. The car will quit before that with 1/2 gallon still in the tank.

If the pump actually said you pumped 13.07 gallons, it was wrong. That happens. I had a pump read that I pumped 21 gallons into a 20 gallon tank once. If that happens, you can report it to your state government, and they will sometimes send out someone to inspect the pumps and fine the gas station for tampering with them to make more money.

Now, to answer your question directly, I monitor my fuel remaining in Torque, which reads it out as gallons, and my low fuel light seems to come on consistently at 2.4 gallons. That means there are about 3 gallons still in the tank, with 2.4 gallons available to me. At my normal fuel economy, I should be able to drive at least another 60 miles before running out of gas.

And in case anybody reads this ancient thread and believes some of the stuff that was posted:

This is nonsense. Since the light comes on when the tank still has roughly 3 gallons of fuel in it, the pump is not running without lubrication.

All modern fuel tanks have the pickup above the bottom of the tank to leave about 1/2 gallon of fuel unreachable. This allows water and sediment to settle down there and not be sucked up to find their way into the fuel filter. The tanks are generally designed so that even spirited driving will not slosh sediment up to the pickup. So this is not really something you need to worry about.

I can put 14+ gallons in my 13.2 gallon tank If I want. Fill the filler neck etc. Not recommended. I always run until the light comes on most of the time filling up @ well over 400 miles. Not worried about sediment etc.

I first heard about not running the tank on empty from my mechanic. He claims that he gets a lot of fuel pump work when the price of gas is high because people run with lower fuel level hoping for the price to drop or because they cant afford it.
