reading back again, that's 140 MILES on one bar, considering the first bar to be 1.5 gallon, that's about 100MPG...

your fuel level sensor could be wrong ?

The fuel gauge in the Yaris isn't the most accurate thing in the world, and seems to be largely graduated at the upper end. As such it's hard to know exactly how much fuel that first pip represented but we'll know how well the gauge is doing overall in another 10 to 14 days when I fuel up again.

Yep, the first drop is about 7 to 8 Liters. But I believe Bailout's 141.2 reading is in miles, which would equate to 226km.

this car cannot run 140 miles on the first bar..140 km is doable but not in miles..

[BailOut]

As I said, it may have just been a fluke in the gauge system but the display is in miles, not kilometers. Again, I see 85-105 miles on the first pip every time, but seeing 142 was a first.

i see i wish i can achieve that the most i had was 140 km on the first bar then again thats on my 3 tank..what was the most you've ran b4 the last bar blinked.. in kilometer ..

[BailOut]

I haven't let it get low enough to blink the last pip yet, and the best I've done so far was 9.516 gallons with the 2nd pip still showing.

At that point the tank had 472.1 miles/759.8 kilometers on it.

its gotta be all highway kilometers... i can barely get this this to 600 km.. and that sensible driving there no pushin it??

Yes, that was mostly highway driving, but I've hit 49.74 MPG on a tank (379.5 miles, 7.63 gallons) while commuting over the mountain to work.

kewl...thumbs up the the mileage...

when commuting, mileage depends much on the engine's rpm, I think in the 5th gear when driving at 30mph the rpm is close to 1-1500. BailOut, could you precise the actual speed/gear ? It looks like the Yaris gets very good mileage on low rpm's

[BailOut]

I never drive faster than 55 MPH and on my commute over the mountain I stay in 3rd or 4th gear between 2,000 and 3,300 RPM, usually going 40-50 MPH (there are a few 20 MPH climbing cutback turns). On flat land I stay below 2,000 RPM as much as possible but more torque is required to climb the mountain.

On the back side of the mountain I make extensive use of DFCO and FAS (Forced Auto Stop - coasting in neutral with the engine off), which greatly helps make up for some of the fuel I had to use for climbing.

wow! vanderkitten drives a yaris? sweet!! im in love with mandy.

Beat the heck out of an SUV!" and be happy with it!

Here in the Bay Area, if you commute on one side of the bay, you get different gas mileage because of prevailing winds, than the other side of the bay. It could be a 6MPG difference, and you wouldn't even feel the wind...

[nsmitchell]

I got 35.3MPG the other day. Mostly city driving. My engine is running buttery smooth nowadays. Since my ticket I've been driving the speed limit and my mileage is reflecting that.

[eTiMaGo]

24.5MPG last tank, higher than before by a little bit, it's promising... Now that I've had oil changed to synthetic, and a lightened crank pulley installed, I wonder how these will affect future tanks...

[jamal1984]

I think my car will stick to either 34 or 35 mpg max, i'm driving hard most of the time, carrying alot of stuffs, it's fell like there is always 2 or more peoples in my car. I'm happy with it.

[marcus]

1st tank 540km with 39.8l fill up = 38.34mi/gal with regular 87 octane
2nd tank ran 535km fill up 38.4l = 39.37mi/gal with premium 89 octane
3rd tank 540km 37.5l fill up=40.69mi/gal with premium 89 octane
4th unbeknown

the funny thing is the last fuel bar started blinkin on 535 sumthin..and i ifilled up 37.5 liter max i can put in there which mean i have about 5 liters atleast..give or take..to about 43 liter tank.. about another 75 kilometers on that remaining gas.. i thought when it starts blinkin you only got about 50 km on it..?????

[argylesocks]

now that its warm out again.. im typically 40-43mpg
