Thanks for reporting your numbers. They are not bad considering that your A/C must have been on all the time .
By the way, do you find your A/C powerful enough?

I've been filled up the tank of my Yaris so many times,
The best of all is only 7.1 something L/100km, average before is like 7.2L/100km or 7.3L/100km.

Today.... I am so shocked, when I go fill up I used up 15.11L for 218.2km, which is 6.92L/100km, i am so happy that it can finally go below 7.0, one big step for me

Like I said before, once I have hit a high 6, I have never hit mid 7 anymore. Hope best for you is still to come.

[Ryu]

Thx man, I forgot to mentioned it got about 10500 kms on it now.
I guess the fuel consupmtion of this car really getting better and better once it is fully break in

[stuffy]

i just filled up today after conducting an experiment, for this tank i really pushed it, fast starts from a stop, pedal down for the whole tank,on the highway i was up to 130 km/h (fast for me) and the mileage i got was 7.2L/100km or 33 mpg (us).
so this was a noticable difference from driving like a grandma, i was up to 40 mpg.
i think driving style is a huge factor.

[Ziv]

Thanks stuffy, heads up for all of us!

[stuffy]

no problem, it wasn't a very expensive experiment, and i have to admit, it was enjoyable.

Not sure if I would suggest such a drastic engine experiment on a very new engine. But then it is a Toyota!!!

[stuffy]

mine has 7700km on it, so it isn't too new

[foober]

Thanks stuffy for doing that experiment. I would think that fast starts and running the engine hard would eat up more gas. My little lift back yaris has so much pep to it I'm having a hard time not going faster than any other car on the road. I'm really amazed how much zip my yaris has. It loves to cruise at 80 miles an hour on the highway. And i'm always having to try and slow down. The liftback just wants to go fast. And I'm still getting 38+ miles to the gallon. I really want to trade my toyota tacoma truck in and get another yaris but I really need a truck.

[stuffy]

yeah, i had beenconsciously taking it easy up to this point because i wanted to see how good the fuel economy could be, but i also wanted to see what happens to the fuel economy when you push it a bit.
i'm sure evereyone here has different driving styles, and with such wildly different fuel economy reports, i wanted to see for myself.

I have a question regarding a/c, yes I know it eats at your gas milage especially if your going up hill on a hot day, but I usually don't use my a/c, only if really needed then I turn it off, anyway since I don't use it, I usually just turn the dial to cold and have the air flow come from the out side, like the vent symbol and the symbol for when the air comes from beneth the dash? Know what I talking about? Its the setting where air comes out of the vents on either side of the cabin but not the middle ones (at least not as strong-hope that made sense) Even if the day is "warm" at least not above 80, it gets fairly cold or at least keeps me cool but I didn't push in my a/c button, I'm I still eating away at gas but not as much if I had my a/c button on? I assume obviously the condenser or whatever is still working just not extra hard cause the a/c is not on, but I don't know the technicalities of it, any help or anwser would be appreciated.

Update:

608km on 36.5L. All city driving.

6.0L/100km

[swng]

Here is my update:

628 km for 42.929 liters. That is 14.63 km per liter, or
41.348 mpg Imperial, or
34.45 mpg US, or
6.835 liters per 100/km.

The A/C was on many times and the time ratio between city and highway driving has been about 35/65%.
Warm weather helps.

[Ryu]

Swng, the fuel capacity for the yaris is 42Litres, isn't it?

[bigsky2]

Another Update:

525.2 km on 37.479 Litres

Works out to be 7.13 Litres / 100 km

Notes:
- 89 Octane (Canada Rating)
- All city driving
- MT
- I usually shift at 2800 to 3000 RPM (see note below hehe)
- Was pushing the engine hard 40% of the time (shifting at 4500 RPM)

Well actually, I think that's the only way to get a/c without push the a/c button. Its to turn the nob pointing to 'air out to dash'. I am sure that is using a/c because its a heck lot cooler. so instead, might as well use the a/c so it points directly to ya. ha ha.

Yes, officially it is 42 litres. However, if you fill up your tank until it almost spills, you will be able to squeeze in more than that amount, presuming that you start with an almost empty tank. Frankly, I do not recommend that you do so. I do that just to improve the accuracy of my mpg calculations.

Thanks for your interest Ryu!
