How far can you go on 1 bar (mileage/tank)

Haven't seen this detailed... Since we all get different mileage, I'm trying to gauge how far we can go on a tank. As an example, I went to 1 bar at 450 miles - drove 30 and filled up. Getting 48MPG (and allowing that the "prius" number is off 5%), I can still expect around 1.5+ gallons left - or an easy 50 miles. This means in theory I can go safely 80 miles on 1 bar.......

Anyone checked this?

In my 2009, I have run out of gas in as little as 7 miles once the last bar started blinking. (I have also driven 30 miles with it blinking, without running out) Now I drive 400 miles and start looking for a station.

I've seen these 1 bar threads go on for pages.

I believe the 09/06 have different fuel tanks. The 2010 has an 11.9 gallon tank - and hence operates likely differently.

Well I had 1 bar on my 2010 and filled it with 35litres so potentially 2 gallon left?

The tanks are different, but not the fuel tank threads. This was supposed to be a wry comment about beating a dead horse. We visit this same topic several times a week, hence the comment about the threads going on for pages.

Understood - but I have not seen it on the 2010 - can you point me towards it? I know there are many on the GenII, but I don't want to just take your word that they are the same - just different tanks - I'm looking for real world info on the Gen III...

(???) isn't 35 litres 4+ gallons (approx - depending on what you call a gallon and where you sit in the world)?

(???) isn't 35 litres 4+ gallons (approx - depending on what you call a gallon and where you sit in the world)? I am thinking I get between 1.5 and 2 gallons left after running 1 bar for some time...

Bob Wilson does this for sport. The base post has his distance and gallon figures, but the problems he describes in that post are a side issue. He posts more data and a somewhat better resolution if you read very very deep into the thread.

35 liters is about a quart over 9 US gallons.

So, the driving distance depends on your mpg number.

Anyway, following is our findings among JP owners.
[table="head"]pip|liters|gallons
1 solid -> 1 blink|1.8|0.48
1 blink -> empty|7.5|1.98

Thanks! It seems BobWilson proved twice that from blink to out is 2.16 and 2.18 gallons. So 2 gallons from blink sounds like a good number to run with... Very nice to know...

If you assume that you will one day run out of gas.

How does that old saying about assume go??? Never assume - it makes ????

I agree with ADSGREEN, I also filled and had 2 gallons left at the time, good for at least another 50 miles on my 2010.

u lie

last bar starts blinking when tank is aprox 12% full, iow, you have the proverbial 8th of a tank.

so figure out how far ya went with the prev 7/8th, and divide by 8. subtract a mile, (jus in case) and tha is how far you can go.

all this assumes the tank was full in the first place.

I think we should stick with Bob's detailed analysis that shows 18.2% (average 2.17 US gallons).

Where in the world did you pull your number from - it sounds official ????

CANVIEW tracks info sent from computer to computer. it tracked gas gauge readings in 2½ % increments in whole #'s iow;

100, 97,95, 92, etc. the last bar would ALWAYS start blinking at 12 %

I'm under the impression that the gauges themselves are just not accurate enough to warrant much confidence in them. In my experience, the gas level depends on the slope of the ground. I noticed with prior cars that when parked on an incline facing uphill the gas level is lower than when parked on flat ground. The reported results on the computers are only as accurate as the gauges themselves are.
