Need help and suggestions about bad fuel economy

[B2FiNiTY]

How does the car run? Any loss of power? Rough idle? Smoke out the exhaust?

The car runs pretty good. It idles nice no roughness, in normal idle rpm. No smoke out of the exhaust. There seems to be a little less grunt, balls, power, etc over the past 8 months but 5 of those months where cold winter in Canada

I too have found that I have decreased my fuel economy in the last 6-7 months. In the summer time I was having no problems getting anywhere from 5.4 L/100 KM to 6.0 L/100 KM. But in the winter time (well since maybe November of last year) I have been getting roughly 7.5 L/100 KM. So roughly a 30% drop in fuel economy. I have seen MANY people here in YW describe that they are finding similar drops in fuel economy.

I do agree with the dealer .... what you are finding is simple winter driving issues and you will not get the fuel economy that you got in the summer time. I expect to drop below 6.0 L/100 KM. sometimes in May when the weather warms and the gas stations change to summer gasoline.

*EDIT* .. If you click on my FUELLY .. you can see the fuel economy decrease that I have been speaking about. I have spoken to the previous owner of my Yaris (he had driven my car 162,000 km of its 172,000 km it now has) .. and he told me that every year there is a drop in fuel economy in the winter time. My scangauge also shows me that I am not getting the fuel economy that I did in the summer time. BTW .. I have NOT found any difference in fuel economy by changing to different Octane gas. You are just wasting your money going to a higher octane ... 87 is just fine for a Yaris.

Personally ... in my case I have gone from a high of 696 KM per tank ... to a low of 492 KM. So I have a decrease of just over 200 KM per tank, so your reduction is not out of the ordinary to what I am seeing.

I don't think that there is anything wrong with your car.

Thanks for the info, glad to hear from someone that deals with winter. I dont notice any increase in milage between the grades of gas. i personally allways run on mid grade have since day one of owning the car. Personal perference i guess. I rarely and i mean rarely fill with 91 or ultra 94 cus its like 15 cents more per litre with no reward. Hopefully once it warms up more here i'll start to see better numbers. Thanks for the info
