Fuel Economy

[bigsky2]

I have drove 300km so far, and the meter is down 3 bars/levels.

It's currently at 5/8 if you count the # of bars/levels.

Speeds have varied during that 300km. The fastest I went was 110km/h, and average speed is 60km/h.

I upshift at about 3000 to 3200 RPM, and regularly downshift at 2000 RPM.

Most of the mileage so far has been city driving, stop and go situations, and a few clicks on the highway.

A/C has been off for the most part...

Update--

Man, I hope these number gets better soon.

390 clicks / 30.5 Litre

7.82 l/100 clicks.

[stuffy]

that's not so good ziv, are you driving like a maniac?

[JaiTomato]

Update:
Just bought second tank of gas. Total of 919 miles and 19.8 gallons. That's an average of 46 mpg.
But then that's mostly highway and I drive like someone's grandmother. (Mine never drove a vehicle in her life)

[stuffy]

i've noticed a BIG difference in fuel economy when i take it easy (like a grandma) or when i don't (like ziv)

Thank you for pointing it out.
But no, I don't really drive like a maniac. Funny thing is, I have been driving mine for roughly four, five months now. I have NO IDEA why it would behave like that. I used to drive a 2.5 Altima. And I tried really hard to learn to drive a 1.5 like a 1.5. I accelate slowly, let the car pass by me and increase speed like VVTI suppose to be. I hardly go over 3000rpm on local. I drive very little hwy lately because I got everything around where I live.
Even so, city shouldn't be over 7.somethin', should it?

I just got my oil change few days ago. Let's hope it helps!

I was thinking, if the number stays that way, can you guys suggest something I can do? bring back to dealer for check up? use other octane than just 87?

Check your tire pressure...make sure you're running at EXACTLY 2.2BAR/32PSI...makes a huge difference on my car...I had my tire pressure around the 29-30PSI mark, and lost about 10mpg on the highway. I'm sure it'd have been even worse in the city.

Ok.... I will try this and see if it makes any different! Sure hope it does!

It is not necessarily driving like a maniac that can hurt fuel economy.

What are the roads like where you drive?

Do you use the AC a ton?

Do you carry a lot of extra gear?

And of course there is always the chance that something might actually be wrong from the factory.

[Ziv]

*Another update thru the long weekend, I actually drove for a lil trip.
402 km / 30.4 Litre
Mostly highway, 80/20 hwy/city
The number still shows 7.56.
When is this nightmare going to end! I am driving constantly at 130km/h in the hwy and hardly going over 3000 rpm in city.*

Let's see...
The road is not too bad, for those of us who have drive around richmond hill knows that it's not the best, but it doesn't nearly have as much pot hole than other cities around GTA.

I am cutting down the A/C since the tank before for last, but it doesn't seems to help as much as I would like it to be.

extra gear? not really, the heaviest thing is me. my gf weight probably half or 2/3 weigh than me and my chihuahua, yeah, he's only 6.9 pounds.

I am thinking I will try check the tire pressure as NickNickNick mentioned, and one step at a time.

Thank you very much for your input. And yeah, it's true that I deals with TONS of stop and go traffic around GTA.

[bigsky2]

6.9l / 100km is the stated mileage for City driving right?

Ziv, your mileage is almost an entire litre over the stated mileage even with your moderate driving behaviour!

I haven't put gas into mine yet, but I am probably going to use 89 octane.

I'll report back when I fill it up and calculate my actual fuel mileage.

[Ryu]

I got a auto trans yaris, it 9300km on it right now, I do the first oil change at 2000km, second at 5000km, plan to do it at 10000km.
The car is well maintained i assume,
but the best I got is 7.2L/100km which is not that good i guess,
even when the summer time is coming right now, I still got something like 7.4L/100m 0.o

I didn't drive like a maniac also, I guess it is due to the heavy traffic in highway 1 in Vancouver when I go to work. It makes highway driving like a city driving lol.

[foober]

I got 40 miles to the gallon the last fill up. And I'm not driving like an old lady. The car has so much pep to it that i'm having trouble driving slow.

[bigsky2]

Fuel Mileage Stats:

7.33 Litres / 100 KM

Based on the following:

Trip Meter was at 459 KM during fill up
Fill Up Quantity = 33.687 Litres

So after doing the math, it equates to 7.33 Litres for every 100 KM based on that trip.

Most of the driving was city driving, and the usual speed was between 2-3K RPM.

I did go past 3K RPM on a few occasions such as on the highway.

All in all, not too bad considering the stated mileage of 6.9 Litres / 100 KM.

I keep my tire pressure at 37 PSI all around and the car just rolls more easily.

I have my tires at 35 psi. I was thinking of putting 37 psi in them. I've heard that can help some.

FWIW, I avoid Sunoco gas because of the Ethanol content which contains less energy than 100% gas and always use Shell which is now fully Top Tier (loaded with detergents) to help keep those dang carbon deposits away.
