Fuel Economy

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.
Some previous pages of this thread contain more discussions on this subject.
Thanks for your interest Ryu!

Thanks for your explanation Swng, then that make sense.

However, I go fill up after 1 bar is gone cuz of the cheaper gas price,
and it turns out 9.621L for 143.2km, which is 6.718L/100km.
I thought the car will stay around 7.3L/100km forever cuz of about 10 fill up after I got the car. I just got 6.92L/100km last fill, it seems getting better and better now.

This car is full of surprise

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)

Update:

415 clicks / 33 Litre
7.95 L/100km 35.54 mpg.
Number one, it was all cities. Two, I blasted my a/c like there is no tomorrow lately, it's been 33+ as of late. Even during the night is pretty hot.

Selecting the fresh air setting only brings in the outside air. So if it is 95 degrees outside, then this setting will NOT do any good. Only the AC button will help. However, on those cool morning or cool evenings, the fresh air setting might be all that is needed.

You are totally right on that...especially when its like 90 and above or even 80 but in my experience any day below 80 degrees, even with the fresh air setting, it gets pretty cool and I'm surprised as this is from the out side air as you were explaining so Sure it may take a little longer to cool than a/c but overall it works, maybe most people won't be satisfied with it but I'm skinny and I'm pretty much a passive person generally speaking so I don't mind as long as I'm comfterable-each to his/her own. If I put on the circulation for internal only, and not coming from the outside it starts to get "warm" but if I switch it back it "cools" the cabin down, so I'm not complaining. Even summer evenings it cools down pretty nicely.

If you wish to rely solely or heavily on the "cool" air from outside, please consider buying a sun shade to prevent the sun from shining directly into your car while it is parked. Even the most expensive types should be quite affordable and they are effective. In the long run, because of the resultant reduction of the A/C's workload and hence improvement in fuel economy, the sun shade will pay for itself.

Just filled up for the first time on Saturday.

Liftback took 11.009 gallons with the odometer on 395.

That's approx 35.9 (US) miles per gallon...meh, not great

Driving was 65/35 highway/city and I had the AC running about 65-75% of the city miles.

The car seems to do much better with the AC off.

Fill up #2:

Took 11.001 gallons with the odometer on 397.

That's approx 36.1 (US) miles per gallon...again meh, but a pinch better

Driving was 65/35 highway; frequently cruising at 80mph (60-65 on first tank) with the AC running about 10% of the city miles.

Couldn't agree more and I believe this is a cheap effective idea. Even if you have tinted your side windows, you could not tint your front dash windows, so a sun shade would be kick in nicely.

Just filled up again. Went 447 miles and used 10.106 gallons of gas. That is 44.23 mpg US.

That is 5.32 liters/100 km.

Since I've had the car, I've driven 932 miles and used 21.64 gallons of gas. That is 43.07 mpg US and 5.46 liters/100 km.

I can tell my car is finally starting to loosen up a bit. I hope the increase in gas mileage continues.

Wow! That's amazing! And your not even at the 1000k mark...very nice I guess cars vary when it comes to "break-in" times, some take awhile and some don't So what's your driving style? Obviously stay within the speed limit? Lower than it? Mostly city, highway, both? I know I can look up how to "conserve" gas and what not but real world figures or personal testimonies are always interesting and informative, obviously it will vary from car to car and enviroment and driving style, just curious.

[foober]

why, did you drive alot of highway miles to get that good milage. That is really good. I'm getting about 38 miles to the gallon. But I'm driving fast and doing half city driving and half highway. I've got 1,700 miles on my little yaris now. Love that car.

[Ziv]

5.32, that is insane!

[why?]

I don't actually drive very much. I go from my home to the nearest center and back, and that is about it. The last time I filled up my car before yesterday was 5/27, lol.

I don't know the exact percentage of highway driving, but I do very little stop and go city like driving.

It might be 50/50 highway at most, and my average highway speed isn't very fast. The limit is 55, and I usually get it up to 60 and let the car coast down to 50.

I'm light on the gas and the brake, and I avoid accelerating up hills whenever possible, even though the area I live in is rather hilly.

Thanks for the response...you mentioned you go somewhere close to you? I thought short trips effect gas milage cause the engine doens't have time to warm up and get to "normal" operating temp but hey there are exceptions. With me my part-time job is 10 min 15 min tops and my car warms up but I'm sure it doesn't warm up to full "normal" operating temp as I'm not travelling far, I'm sure that it effects my milage. Oh well!

Thanks for sharing your experience. You must have done something right, and it does seem to me that you have, to achieve the good results that you posted on 06-22-2006. Please keep on posting as you get better and better mpg numbers.

Well for me the cool light usually turns off before I get out of my neighborhood.
