I just started using 94. I am in Canada. I have 48,500km (not sure of that in miles), and am getting approx 400km (miles?) on a full tank.

have you noticed the drop after you started to use the 94 octane or before? Maybe that's just too much octane for what your car needs...there's been a lot of discussion on this recently. Do you have a tune on your car? If not, then you don't need to run 94 octane...89 is recommended. The car is tuned for 89 but can survive on 87 if needed to.

I just completed a 360 mile round trip to Ottawa on 91 octane and averaged 23.7MPGs with 3 adults and a 12 year old in the car as well as a loaded trunk...just for comparison's sake.

10-4 on that. I just entered some of the outstanding fuel receipts into my spreadsheet (I have one per car) and saw that in May on a trip back from Toronto, I filled up just before hitting the highway and filled up again 1 whole day after returning to work (that's commuting in traffic to daycare, then more traffic to work, then traffic to daycare, and heavier traffic back home, then filling up the next day). The result: 25.something MPG US.

That was with 2 kids and 2 adults in the car, also with a full trunk.

If I had taken the time to fill up immediately upon arrival, who knows what kind of fantastic result I would have logged! :knockout:

That was a steady 105-110 kph the whole way, with 2 food stops along the 401. Esso 87 on the way down.

lol...I was trying to keep it a steady 105-110...but I HATE it when others pass me and I pass no one! I had a few sprints to 125 just so that I could say that I passed someone! Really...I kept it pretty much in between those kph that you stated...I found it to be a good compromise between achieving decent MPG, and getting to our destination in a reasonable time frame! I mean, I could have cruised at 80kph but that's just downright dangerous! Today, doing 110kph, I was passed by a Ram on the 40 pulling a nice sized camper behind it doing about 120! ...

hey Steve...I'm sure if I drove like grandma all the time, i'd achieve those number that you had!
