Fuel Economy

[swng]

Sorry, not really have an answer for you because the difference you have achieved seems big. It may be a good thing to know such a way of getting good fuel economy though. Just hope that it is repeatable. Frankly, and I think you have implied it too, this seems to run against common sense.
However, if you fill up often, you carry a full tank load of gas often. If you travel with a half/near empty tank, you carry less load.
There are enough reasons not to drive with a near empty tank, but the fact is doing this saves you a little fuel. Just a little, hehe.............
Just added the site you recommended to my list of favorite sites. Thanks!

hey guys back from another trip from toronto, full my tank to the max in montreral. avg speed was about 140km with a/c on the whole trip ,3 adults and alot of bags, Did montreal to mississauga in about 5 hours then drove back to ajax did about 620km starting to get worried the last bar was flashing since about 575km. my car is manual. good air pressure 35psi in about 25 degress heat for the whole trip. when i fulled up the second time the car took 40 liters.

Still have just over half a tank left from full tank, and i've driven about 190 miles so far. Thats about 38MPG if i've only used 5 gallons on the 11.1 gallon tank. These are all just measurments from my best analysis. Its still on the first tank of gas, i got the car yesterday. I'll do another calculation when i refill the tank to find out how much i used from the first full tank.

That's roughly 43.7 mpg(imp). That's good considering the load, the A/C, and the speed.
I have noticed that the last bar will flash faster as the fuel tank gets closer to emptiness. When it happens, I would drive to the nearest gas station without more hesitation.

I got 39 mpg on my first full tank of gas. About 50/50 on city/highway driving. I was IMPRESSED....

Please prepare to be more impressed later, as your engine breaks in .

More and more fellow members have already gotten or will soon be getting their new cars. For the benefit of all, would the new car owners please post their fuel economy here? The bigger the sample base, the better.
All are welcome to share their fuel saving tricks here too!

Here's an update. I've driven 2623 miles and bought 60.012 gallons (6 fill-ups). So that's an avg of 43.7 mpg.

Update:

I break it under 7 again! yaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahooo.
460 clicks/32 Litres
40.625mpg
** 6.956521 L/100 clicks. **

To all new Yaris drivers, I used to be just like some of you, always near 7.5 or so. But for me, after the first oil change and over 9K-somethin' clicks, it's looking all good from here. =)

[swng]

I also had an oil change just a while ago. I will post my results soon.
The tank is still half full now. Will see if the oil change can really help.

Yet more data (FWIW)...

Closing in on 10 000km. I continue to see a general trending downward in fuel consumption, lifetime avg consumption now sits at 6.92L/100km. Data from last 4 tanks:

6.88L/100km
6.05L/100km (lowest yet )
6.24L/100km
6.13L/100km

... under these conditions:
- 70% hwy/30% city
- 10% ethanol fuel
- AT
- some A/C use in recent weeks
- 100km/h-105km/h hwy cruising speed
- tire pressure = 240kPa (35psi)

I find the current numbers (in the low 6s) quite acceptable (down from low 7s during the winter). At this point, I wouldn't be surprised if the numbers have bottomed out for me, as the peak summer months are just ahead (i.e. more frequent A/C usage), and I don't know how much more a factor mechanical wear-in will play. I'd be cool, though, to break into the 5s.

Owned my car a little over a month...5th tank of gas I believe. Put on approximately 350 miles a week. So far, just averaging 32 mpg...hope it get's better! About 1/2 city 1/2 highway. Up and down 1,500 ft. elevation daily.

That should be equal to about 38.4 mpg imperial, presuming that you are posting your mpg as miles per US gallon. That's quite close to the average I have in mind. Considering that your car is still new and the elevation could have adversely affected your car's performance slightly (fuel burning is likely to be less complete on high altitude), I would say that your results are not bad. Keep on posting your numbers please.

So, with a fully loaded Yaris (two people, two medium sized dogs and all my photo equipment - printers, a couple computers, monitors, etc.) we got 41MPG over a 400 mile trip going between about 70-80mph. Even with a margin of error in there, we're extremely happy.

[redglare45]

Hey guys, here's how I'm doing: Filled up yesterday and put in 10.8 gallons, pretty close to our 11.1 gallon tank huh. Before the fill up I had gotten 368 miles, so it seems that I'm getting 34.07 miles per gallon. I've done mostly city driving, so I guess that's not bad.

[fearturtle44]

Yeah, 34mpg sounds right with mostly city driving. I got 39mpg with 60/40 highway/city driving. I am extremely happy with the mpg as well as the comfortable ride.

Update:

450 Clicks / 33 Litre
7.33 km/100 or 38.5 mpg.

Mostly cities and I think the numbers is staying pretty well lately, all near low 7 and high 6s. hehe.

[adnanmalik]

I have got Yaris 2001 and my car has given me 570km in 38 litre
