Fuel Economy - Page 45 - Toyota Yaris Forums

As the starter of this thread, I am pleased to be at your service. 7.9 liters per 100 km is about 29.87 mpg (US) or 35.7 mpg (Imp). Here is a useful link to help do the conversion (It was recommended by another member earlier):

http://www.roity.com/petrol/metcalc.html

Here is another one:

http://oee.nrcan.gc.ca/transportatio...ut.cfm?attr=16

If you use the second one, which is Canadian, you can type in your numbers, get the calculated results and then copy and paste them to your next post on this thread. I think if you only copy and paste the few lines containing your fuel economy, there should not be any copy rights issues, but correct me if I am wrong.

Enjoy!

I don't know if the Lower Mainland, Vancouver in particular, is receiving the winter blended fuel, but my mileage has worsened since the end of summer.

But at the same time, my car has changed as well, so I am sure that also contributes to the poorer mileage.

lol, nice one eTIMago

i suppose violin is right, soviet russia did use the metric system, but then again, so does the entire planet.....except i think there are still 3 hold out countries, still clinging to the past, Myanmar, Liberia and what the hell is the name of that other place?

Looking forward to reading your further reports.

nsmitchell · 12-06-2006, 09:16 AM

I got 31.5MPG the other day. Lead foot with about 50/50 city/hwy. I need to lighten my foot so I could get the 35-40MPG like everyone else.

TDL · 12-06-2006, 11:23 AM

Does your gas mileage get better once the vehicle passes the 1000 miles break in mark or ? My first gas tank I got 375miles, second one I got only 325miles, 3rd looks to be less. Not sure how anyone is getting 40+ mpg.

Slow starts, 65-70 on the highway.

I bought this vehicle specifically for the gas savings.

Liftback, manual.

Thoughts?

stuffy · 12-06-2006, 11:51 AM

it appears you are getting about 25 mpg right now, assuming you are filling up a full tank (approx. 10 galons u.s.).
this is exactly what i was getting a year ago when my car was new, and with winter fuel.

now, i'm getting about 34 mpg around the city with winter fuel.

I had a similar experience to yours i will share later. The only thing i can think is that there is a thread on here that shares the experiences of one guy who ran out of gas and it caused him to get someting like 19mpg for his next couple tanks. It turns out that there are sensors in the tank that adjust your fuel consumption somehow for very low feul levels. Apparently that is one reason why the manual recommends filling up when you have two bars left.
Also, according to the NHSTA every 10mph extra you travel on the interstate cost an average of 20% fuel economy. Thus if you are going 70 instead of 60 you will use 20% more gas. That isnt exact im sure, but you can get the idea it is a pretty handsome number.

My first tank got 29, i filled up and i only had 0.8 gallons left in my tank, my second got 25mpg, my third got 23 (doing about 80-85% highway at 60mph steady) and then i filled it up, took a road trip on the interstate and i got 34 mph each way going over 70, probably averaging 75 mph, a little 85. (only 100 miles each way though). Earlier I had taken it in and had the transmission inspected and everything checked out ok. My theory is that when we run the fuel so low it messes up the sensors, but after a point they automatically reset--seems to have happened to me as after i filled up again i got such huge improvments driving so fast on the interstate. There were a couple other people that talked about this on here elsewhere.

eTiMaGo · 12-06-2006, 12:32 PM

I agree about the low fuel thing, kinda experienced it myself (i think)

When I had upgrades done to the car, the guys at the workshop left the engine running most of the time, and it actually ran completely dry.

Once it was refueled, and the car back on the road, I found I had crappy mileage too, half a tank only lasted about 150km.

Then, a couple of days later, I was on the highway, pedal to the metal in 5th, when the air/fuel sensor meter I installed pegged the needle on very rich, and the warning buzzer went crazy for a little while. Then, the meter went back to normal, and so far, normal mileage seems to have returned.

I'll be sure to refuel before the gauge shows two bars from now on

Nutzoids · 12-06-2006, 01:43 PM

Alright I have a US Yaris HB... I have 2 bars left and I want to find out what my MPG was... What equation should I use? How many Gallons of gas fit in that tank? Do I just refill the tank and minus that number from the size of the tank then divide that by the amount of miles I have done? There are too many numbers here with the Metric/IMP/ US conversions…I’m slow and need to be explained things slowly!

hystria · 12-06-2006, 01:53 PM

100% highway at 3000rpm (70mi/h)
39mpg

100% stop&go city, moderate driving, cold weather+snow
26mpg (35 miles on a bar)

that's for a 4000km on clock, 5 speed Hb with original oil/filter

Just changed oil to synthetic & waiting to see if ther's any change in mpg

What do you mean by on a bar?

fuel level bar. of course, this is just a first approximation of my city mileage as I just moved into the city. i'll be back few tanks later for a more precise mileage

stuffy · 12-06-2006, 06:21 PM

nutzoids: just fill the tank, note how much fuel was put into the tank and how much distance was travelled by noting on the odomoter,
i have a little pad i keep in the car and once the car is filled, i write down both numbers and do the math at home.

divide the distance travelled by the amount of fuel used.

it's good to average this over a number of tank fills to get a better idea of fuel economy.
