I share your pain. It cost me 70$ to fill up the other day and I still only get 12L\100km highway or 19MPG. at 17,000kms I'd expect to get something a litle closer to the estimated 8L\100km or 28-29MPG. A few weeks ago when we had that -30 Celcius weather I was scraping for 16MPGs as well. I called my dealer and he still seems to think that it's because of the cold weather but if it doesn't improve they'll take it for a week and check it out.me thinks everyones lying or getting different MPG out of there CT as I'm just figuring out my MPG on my CT and this last week I got 15.6 MPG with simple commutes to work and one 30 mile hwy trip.I'm in shock as it was $52 to fill it up for a simple weeks worth of driving and I'm already getting the gears from GF who wanting the gas sipping Venza that has twice the MPG rating as were getting,15.6 mpg combined arg. I hope the aftermarket performance chip isn't snake oil and can get 4-7 mpg more outta this guzzler else I'm in trouble.
