yeah lots of short trips kills the mileage on any machine even more so the colder it is.

Did you buy a used Yaris with 1100 miles on it? How much did you pay?
I have the exact same Yaris and I ain't getting nowhere near 37MPG routinely.
I wonder if some engines were built a little more loose, or if you are just lighter on the pedal than me. Do you have many hills where you live?

Just cuious.

I get 36.0 mpg average. If I drove 110 to 120 miles per day average like pdarnell, I would expect that extra mpg. My driving style is that I don't try to accelerate very hard, I don't care much if the car next to me gets ahead of me (much). I tend to hold my own though on the highway. I get real antsy if I'm being continuously passed. That means I'm doing around 75 to 80 mph on highways usually. Not much around here in the way of hills, definitely nothing around here that you would consider to be a mountain, nothing even close. (Central South Carolina - midlands)

I just started driving my liftback again after having it parked up for 3 weeks. I'm seeing a 5% drop in fuel economy. Granted, the weather had become close to freezing since I last drove the car, but the really really cold weather is still awhile aways. I'm hopping the 5% drop isn't going to get worst as the weather gets colder, or I'm gonna be pissed. I got 33mpg in the last tank, when it's usually 35mpg.

With any fuel injected car your mileage will drop with colder weather

Colder air temps or humid weather = more oxygen and more oxygen requires more fuel to maintain stoich (proper fuel air mixture)
Best thing you can do for you car here in Ontario for the winter is run a synthetic 0w-30 engine oil. If you have an manual trans swap out the trans fluid and replace it with a synthetic 75W-90
I prefer Amsoil or Redline products and they will likely give you the best performance and help restore the mileage the best.

31.6MPG - While driving it like a "Bat out of Hell!"

swng · 10-27-2006, 11:00 PM

Thanks for posting your results.
Really not bad considering the driving style that you described above. I guess if you choose to drive leisurely, you will achieve something closer to the factory quoted 34 mpg for city and 40 mpg for highway driving (http://www.yarisworld.com/forums/sho...052#post33052).
Driving for fuel economy is almost as addictive as any other driving style hehehe.......
Have fun!

AlexK · 10-28-2006, 05:34 AM

My best tank distance so far:
506 miles on one tank (10.29 gallons US). Works out to 49.2 mpg.
This tank was all city driving (mpg is lower on the highway). No trip longer than 15 miles and a lot of cold starts.

Secret:
Shift at low RPM (2000-2500)
Use 1/3 to 1/2 throttle to accelerate up to speed
Once up to speed, coast in neutral as much as possible
Drive like your brakes don't work... coast to a slow speed before stopping
Try to maintain momentum around corners

MPG since new

zyovka · 10-29-2006, 09:37 AM

Oh, well, our first experience with milage, 'cause first tank of gas is over. It was like 70/30 driving in the city and on the highway. Estimated mpg came out to 34.4 miles per gallon. To be frank I expected a little bit better milage, but, hopefully, because of our engine still has only less than 400 miles, may be it will break-in. I also noticed, that people here are getting better results driving manual Yaris and mine is automatic.

[QUOTE=AlexK]mpg is lower on the highway [QUOTE]
only time gas milage is worse on the expresway is if you drive a hyrid. Stop and go traffic uses much more gas than staying at a constant speed

07WYarisRS · 10-29-2006, 10:26 AM

or unless you drive it too fast
stick with the spped limits and you will use less fuel on the highway

34.4MPG with only 400 miles of break in is AWESOME! With 30% city driving, that is even better! You should be excited!

Ok - NOW I’m really confused…
I’m not a car guy so please explain:
If cold weather will cause you to see a drop in mpg then why
doesn’t adding a Cold Air Intake do the same thing???

As long as it is not TOO hot or TOO cold, a cold air intake allows for more air to flow through the engine, which somehow (i'm not technical obviously) leads to a small increase in engine economy. it does this because it is taking air outside of the car at ambient temperatures rather than the air inside the hood, which is hot because of the engine.

In colder or hot weather, i believe the efficiency effects of a cold air intake will diminish. someone with more knowledge correct me if i'm wrong!

theladybug · 11-01-2006, 12:28 PM

I'm not too thrilled with my fuel economy. Granted, I'm only a quarter of the way through my third tank, and didn't count the first one that the dealer put in, but still. I thought it would be better.

My YarisHB has just over 1000 km on it now. I typically drive about 90km a day, all of it in bumper to bumper rush hour, stop and go, highway traffic - which in my opinion, is way worse than city driving as far as fuel economy goes. [Those of you who live in the GTA know what the 401/427/Gardiner are like during rush hour.]

So, on my last tank, I got 479 km out of 38.45 litres of gasoline, making my consumption 8.02L / 100km. That was driving very conservatively. I knew it probably wouldn't hit spec, but I didn't think it'd be THAT far off!

While I hope my numbers get better, I will say that I am already getting infinitely better fuel economy than I was on my previous vehicle - a '98 Neon - and than my husband is getting on his current vehicle - a '98 Sunfire. So I'm still happy!

stuffy · 11-01-2006, 01:44 PM

theladybug,

you will probably see some improvements in fuel economy once your engine breaks-in a little more,
but with the type of driving you are doing, i wouldn't expect to see great numbers,

i average about 34 mpg (us gallons) or 6.9L /100 km and my driving is mostly city driving with just short trips,
but the best i have achieved is 45 mpg on tanks that are entirely hwy driving.
