How many MPB (miles per bar)? - Page 2 - Toyota Yaris Forums

Split · 02-10-2009, 02:54 PM

its so inaccurate.. the first bar is like half the tank.

nemelek · 02-10-2009, 04:00 PM

I get 75-80 on the first bar. Most cars that I have owned are inaccurate. I use well over 1/2 a tank by the time the gauge hits the mid point.

SilverBack · 02-11-2009, 02:47 AM

I'm getting about 60 miles first bar because I top-off to the next dollar or gallon, whichever comes first. Next bar I get 50, and then 40 til the next fill-up. 350 per tank on average, not too bad

Other times my tank sometimes gets between 375 and 400 under same conditions and speed, not sure why

Inspector14 · 02-11-2009, 08:22 AM

up here in the snow and the cold my new yaris (1300mi on it) gets about 40 on the first bar, 215 miles total to the tank. its 100% city though.

reaching down to the 8th bar, when it starts blinking, like its on crack I've managed to get 407 miles. Just just basic math to calculate it. Mileage at start of fill up, subtract final mileage w/ start mileage, and divide by 8 i think.~

First bar, or equally each bar, gives me about 45-50 miles, but that does not correlate w/ the above i mentioned. I'm doing about 70-78 on Hwy 101/280 up to Daly City, so not so high for me i guess...stupid school~

Kaotic, i dont know how you're getting 70 on the first bar, damn yo!

Really; say it ain't so, Kao!!!

I still get about 60 on the first bar; not so spectacular.

Okay, that's YET ANOTHER reason to prefer my old Suzuki Swift; that gas gauge wasn't "fancy," but it was dead-on...

Drop it down to 60-65 mph and you'll reach 70 miles for the first bar.

As with all gas tanks the fuel gauges gets more acurate the lower the fuel level. Typically you should get 50 miles per bar with the first bar being anywhere from 60-85 maybe even higher depending on fuel level and driving style and about 220 at half way. I have gotten 143 out of the first bar and on that tank I had 479 miles with probably 30 to spare before fill up. Standard driving with out any real lead foot should get close to or just over 400 miles with filling up to the first click. My experience is that the tank can actually hold over 13 gallons of gas. Our car can go over 500 on a tank if you know how to do it properly. As for me I'm thinking about doing a custom tank that holds 20 gallons.

b_hickman11 · 02-11-2009, 08:43 PM

I get 75-80 miles on the 1st bar for practically every tank. The most I have ever got on the 1st bar was 120 miles, when I was on a long road trip. I got the 120 in the middle of the summer (about 100 degrees outside) and with the AC running the whole time.

CTScott · 02-12-2009, 10:08 AM

^Good write-up - It's like an episode of Mythbusters.

The one thing that I find a bit annoying with the whole inaccurate fuel bar issue is that the bars are driven by the microcontroller that runs the instrument cluster. It receives the direct input from the fuel level sender and turns on the appropriate number of bars based on that data. So, it would have been incredibly easy for the SW Engineer to add a fudge factor so that the bars behave in a more linear fashion.

I've had the exact same thought! (and I'm a SW Engineer) Why couldn't they have compensated for the tanks shape? At least get closer! I notice that my first bar lasts around 84 miles and then the last bars disappear before I even notice that it's that low!

churp · 02-15-2009, 02:00 PM

I've always assumed it was manufacturer practice to dumbdown for the typical consumer.......can't count how many times I've heard "...my car gets great mileage, my 1st quarter tank went xxx miles!"

NJBob · 02-18-2009, 07:22 PM

Who pushes the envelope? When I get down to the blinking second bar, I panic and fill up. The book says 1.6 gal. left at slow blink and 1.1 at fast. Who has waited that long or beyond and what happened?

I hope the 1.1 gal. at fast blink is correct... When it hits and I'm too far from a station i think " well with the gas mileage I have at least 30 miles left" and I don't worry about it... I suppose what I should do is get a gas can full and test the miles from fast flash to stall, but I hate to think of the sludge in the bottom of the tank getting sucked into the fuel filter...

Yaris Hilton · 04-04-2009, 10:28 AM

I filled my new sedan within 5 miles of switching to the last bar a couple of days ago. I fill it fast, then when the pump clicks off I "top" it slowly till it clicks off once more, not really topped, for consistency. It held 10.05 gallons. IF it's true that there's 11.1 usable gallons in the tank, I figure there's a gallon left when the blinking last bar appears on mine. I'm not going to push my luck.

This mirrors my own line of thinking exactly. The very first tank I ran through my Yaris I drove until the last bar had been been blinking for quite a while. When I filled up I was a little shaken when it took 10.66 gallons until the pump clicked! Evidently the fuel pump will continue to pick up fuel with a very small quantity remaining. Now if I've been driving on the second to last bar for a while I think about gassing up and most definitely by the time the last is blinking.

*** On a side note I just remembered a funny story from my childhood.

I was riding with my Dad in his pickup truck and he said "We'd better get some gas-the gas guage is almost down to 'P'".

"P?", I asked. "What does that mean?"

"Pedestrian!" he replied. ***
