Fuel Economy - Page 94 - Toyota Yaris Forums

swng · 09-25-2007, 12:44 AM

At the earlier days of my Yaris, I sometimes filled the tank until it spilled and I have for once exceeded 180 km with the first bar. I believe that some member(s) has/have done even better. Now I just fill till the nozzle automatically stops and I get more or less what marcus gets as described in his above post.
There are lots of road works on my way recently. My fuel economy is bound to be adversely affected. I am not too optimistic about the result of the current tank.

Here's a blurry shot wich i've made this morning with my phone.

If you can read it a little bit, my mileage dropped to 4.9 L/ 100km, almost 48 MPG. You have to keep in mind that i always drive just around 77 mph.
If i lower the speed to around 62 mph i'll get a much better mileage, it's oh so fun with my diesel

BailOut · 09-25-2007, 09:55 PM

I fueled up this morning with 10.436 gallons after 538.8 miles driven for 51.629 MPG US.

Goalie · 09-25-2007, 10:17 PM

Show off Brian. Nice job!!!!Wish we had a diesel here in the US. Nice little 3 cyl turbo like in the Smart Car would be sweeeeeeeeet

Hi, I am a new member to this forum. I found this thread very informative and resourceful. So, I thought I might as well share my fuel consumption numbers with all of you. Firstly, we have two Toyotas in our household, namely a 2007 Yaris LE (5dr)(auto) and a 2002 Corolla CE (auto). The average number for the Yaris is 6.54L/100km (15.3km/L). The average for the Corolla is 6.83L/100km(14.6km/L). The numbers represent purely highway driving (~95%) of 37km(one-way to work). I am a bit concerned considering that Yaris is a lighter car (1050kg) compared to the Corolla (1200kg). I usually drive at around 110-120km/h on highway 401. I will keep you updated with my future consumption numbers for the Yaris. Hope this was a useful piece of data.

voodoo22 · 09-26-2007, 09:19 AM

I don't know what's up with my FE on the past couple tanks. I used to always get very close to or pass 500kms on the 5th bar but the last 2 tanks I barely clear 460 before that bar goes. I'm chalking it up to the colder weather, but it's been warm this week. I don't know what else could be causing this. I just passed 8000kms and am going to do the scheduled oil change tomorrow, but I did an early oil change and check over at 3500kms so I can't see it being something wrong with the car. Tire pressure is fine, nothing has changed. Anyone have any ideas what it could be?

BailOut · 09-26-2007, 10:45 AM

You can't go by the bars, voodoo22. They are not linear nor static. The only measurement you can count on is at the pump (dividing your distance traveled by the amount of fuel you fill with).

Even then your best bet for measurement consistency will be to always fill up at the same time of day (i.e. on the way to work in the morning), at the same station and at the same pump.

Thanks BailOut. I do fill in at the same station and same pump at about the same time every fill so that should help, but lately I'm using an extra .1 to .2 litres per kilometer.

I didn't realize that about the bars. I don't much care for them and would much prefer the return of a needle display. I was wondering why some of my better tanks of gas I would often start out with 120 kms or a little more on the first bar and 100kms or more on the subsequent bars, but lately on the bad tanks of gas I'm getting 135-140 on the first bar and then not even 100kms on the bars after that.

Lafiro · 09-26-2007, 06:27 PM

I get the same thing.

This tank si strange cause I did not follow the rules of accelorating slow and not driving at the speed limit, but somehow, the half-way point on the indicated didnt lose that bar until 242miles!!!! Which is a record for me!!

But watch it start blinking when I hit 310miles or so :( I dont get how I lose 3 bars in 60-70miles, but lose the first four after 200-240miles.

As you described it, it is strange. IMHO, under normal conditions, it is unlikely that three gauge bars can be lost in a matter of just 60-70 miles considering that the same car has covered 240+ miles for the first half of its fuel gauge range i.e. half the number of the bars (NB:not the car's real range). It is my presumption that all relevant conditions have remained more or less unchanged. Otherwise, anything can happen, right? Yet on the other hand, it is not too unreasonable for the last bar to start blinking at 310 miles (about 500 km). All gauge bars are understandably not equal when it comes to the distances that they individually cover but your case appears a bit too weird.
The car should presumably be under warranty and I would suggest taking it to the dealership for a checking.
All the best!

Lafiro · 09-28-2007, 12:01 AM

I did that one when my last bar started blinking at 240miles or so for a few tanks. They said it was bad gas, and even took a cup of it out and showed it to me in the room with everyone and they said it smelled bad. Lets just say I never went nor want to go to a BP station ever again. But they told me that they would not do the work to check the fuel tank/filter, and that the ECU didnt show anything wrong, and this was even after I insisted. Whatever maybe I was pushing it but I dont like how I drive like a grandma most of the time, and all I get on average is 3mpg more. :( I could race the car all I want and drive at 90mph all the time and I would always average atleast 26-29mpg. I drive slow, and now its just 32. Lets see tomorrow when I fill her up.

And that was also the tank after pushing the car to the gas station cause I ran out of fuel!! Stupid me forgot to put gas i the car and ignored the miles that day. Ran out completely at like 336miles or something which isnt that good either.

Anyway, its at 310miles right now and still got a bit more I suppose before it starts to blink!

Maybe it is the crappy air filters they are putting in the car?
I mean I got the pil changed to synthetic and changed the tranny fluid and it didnt really do anything, but the car felt a bit stronger.

swng · 09-28-2007, 12:23 AM

Thanks Lafiro for the additional information above and the friendly communication as a whole. I think you have done a lot of things conscientiously trying to bring about some improvement. Let's hope that it is just the gas that has caused you the relatively low F.E., as the dealership seems to have claimed. Frankly 26-32 mpg (US) is not too good but also not extremely bad. IMHO, improvements are not impossible.
There are better ways to drive to save fuel other than just to drive like a grandma

. Here are some tips that may be worth going through (again, if you already have):

Bredayaris · 09-28-2007, 12:36 PM

I've got my 50 mpg today, but i can do it much better.

My boardcomputer said that i can drive 434 miles with one tank of diesel, but my boardcomputer is very negative. And it's better to have 1/4 filled up of your fuel tank.

In the Netherlands it's called : ''het nieuwe rijden'', the new driving.
You have to drive in 4th gear if you go 31 mph, but if i do that my dieselengine doesn't like that. It revs less than 1800 rpm at 31 mph.
43 mph in 5th isn't good for my engine too i think.

marcus · 09-28-2007, 12:53 PM

well i finally hit the highest mileage average.. 44 miles/gal. about 15.6km/liter, and 6.4/100 km... i had to go back to premium gas. I know I know "premium doesnt give you better gas mileage" but hey i gain 3miles /gal switching over.. or it could also be the break in period kickin in..big coincidence though..i got almost 10000 km on her. oh well...lets hear the negative comments! hehehe..

Hey thank you.

I will follow this. Would it also make a difference that I have two nice amps still connected to the battery? I would assume all extra demand on the alternator would then mean less miles per gallon? Specifically since I removed the two sub's the 2600watt amp is still connected. The 4 speakers then are connected to a 1200watt 4channel amp which is always on and I always listen to music. Maybe this is affecting it as well? But I cant assume this will affect it any at all?????

petesimac · 09-28-2007, 02:22 PM

Okay, so I had my first instance of premature bar droppage; I usually get about 46 miles per bar, not including the first one which varies from 68-75 miles, and the second one which sometimes gets me 50+ miles, so when my bar dropped 20 miles short of this, I was disappointed. It happened while idling in a bank teller line; I would normally have turned my engine off, but there was only one car ahead of me and it looked like she was done. So as I'm waiting, whoosh, the bar drops, and I grumble. Once it's my turn, I pull up and turn the car off. After my business, I turn the car back on, but the bar is still down. I head off down the road, I'm coasting down a hill and "pop" the bar comes back :) So, how often has this happened to any of you, and why does it happen? Any thoughts?

gauge bar aint accurate..actually they are very inaccurate... all that matter is what you get an the end of your 7th bar..mine leaves me about 4- 5 liters once the last bar starts blinkin..

hey marcus, i also noticed an improvement in fuel economy when using a tank of premium gas.

i made the same 600 km round trip on two weekends, one with premium gas and one with regular.

the premium tank was 41 mpg with poor traffic conditions, the regular tank was 36 mpg with better driving conditions.

i know they say it doesn't make a difference, but that has not been my experience.
