Fuel Economy

[Thotprawsis]

Well here are my numbers so far. In the city I'm avg' 34mpg and on the highway I'm getting 43mpg. I'm just under 3000. I'm going in for my first oil change. I hope to gain a little more.

Change that oil to a good synthetic and enjoy even better mileage (albeit slight).

I got my Dragon short ram intake put on last night so I'm interested to see if it makes a difference in mileage. It's going to be hard to keep my foot out of the gas.

41.-41.5 MPG last tank..

thx for that info.

[uncleyaris]

my last fill, showed 46.9mpg. Damn I love this car. Gonna drive real grandma and aim for 50 mpg, lol

[slvryaris]

Yaris now has almost 32,000 miles on it and still getting 36-40mpg

I did the TRD cold air induction on mine & right off got way more miles out of a tank ,plus way more pop off the line . With the reuseable / cleanable airfilter & added fuel savings it's gonna pay for it's self real soon

Depending on how much highway driving I do, I get anywhere between 550 and 650 km to a tank. Costs me about $40 to fill up with gas at $1.09/litre

which is between 38-44 mpg. Not 2 shabs - I'm happy with it.

Didn't see any real improvement in mileage after installing the Dragon intake. I got 40mpg this last tank with A/C on about 60% of the time. Still can't complain about that. :)

I've gone about 5,300 miles so far (a mix of city highway- typical NJ driving). I've gotten 38.5 miles per gallon peak and total average is 37.5 mpgs...all with the A/C ON and my lead foot!

MT, regular 85 octane gas @ $3.80/gal

Hoping to get the TRD CAI and improve things a bit...

Will a cold air intake really increase fuel mileage? I've read different opinions on this.

Brief follow up to Post #1376:
Got approx. 509.8 km (316.79 miles) with 35.787 liters (9.45 US gallons).
Translates roughly to 40.24 mpg (Imp), or 33.51 mpg (US), or 7.02 liters per 100 km.
Additional Info: Load = 2 people + some baggages most of the time. City/highway ratio was about 40/60. A/C used a lot during the tank. Tire pressure was 34 psi all around. Regular maintenance.
Comments: About average for me. Still comfortably above EPA numbers.

nice work swng, i'm still a bit too much of a lead foot to get your numbers.....
but i'm close.

[nuarch]

i recently traveled from Miami, FL to Dallas, Tx
and recorded how much i filled up each time
and the mileage i had at next fill up

the car is a 4 door yaris sedan
trunk and back seat full of my life
and when i say back seat full, i meant from bottom
to almost the top of the windows
2 full size adults
and with a total trip of
1623 miles, i did a little side driving
i fueled 4 times and got an average of 39.6 mpg
there was a stretch through tallahassee, fl to port arthur, tx
that i got 43mpg
overall i was pleased with how well the car performed
and i feel sorry for its rear end, because with all the junk back there
any low dip that i was caught not paying attention to
gave me a nice reminder of how low it was back there

I am sure you will do really well sooner or later. You described youself as lead footed. I think there is a possibility of it being an overstatement. Even driving relatively fast can sometimes have good effects on F.E. Even if you do not pulse and glide (I rarely do), you can still accelerate a bit before a hill (subject to safety) and use the momentum to go up the hill. That will be a lot better than accelerating during the climb. Well, just an example to illustrate that going fast at the right moment can help save fuel. I by no means want to encourage speeding.
Good luck to all of us who make use of this thread to share experiences!

Nice numbers nuarch!
Just for some discussion, I believe for long trips over smooth road surfaces with few stops, load is often less harmful to fuel economy than other factors. What a heavy load (I mean one within safety limits) can usually do, apart from affecting your handling, is to cost you more fuel to reach the desired speed and more heavy braking to slow down/stop. Yet, the momentum caused by the load can actually help you maintain speed for a longer distance. This also means you can lift your foot from the throttle earlier whenever you want to slow down/stop.
Once you reach the cruising speed, friction of all kinds, including wind resistance, becomes the main factor adversely affecting your fuel economy. I venture to guess that your long trip must have been a smooth one (except the unexpected dips you mentioned) with few stops (relative to city driving), making your mpg numbers so adorable.
I envy you for having had the opportunity to travel such a long distance. I struggle with city traffic every day. Even my so called highway drivings are short and full of needs to slow down or stop.
Still, just like you, I am happy with my Yaris!
Thanks for your thought provoking report above!
