BTW I do run premium fuel, and 0w-20 full synthetic oil and have a CAI, header, and exhaust wich all contribute to a more effecent motor therefor better MPG.
wow. I'd expect CAI and 17in tires to have a negative impact on fuel consumption. What's the type/make of your tires and brand of alloys? I wish I could get those kind of results. I've yet to get over 40mpg (US), but hopefully fuel consumption will increase once I switch to synthetic.

if you're mostly driving in the city, it's hard to get 40mpg. if you're driving mostly freeways, try to stay at a constant speed throughout the trip. 65 mph gets me 39 mpg average. keep in mind, that's an average of my type of driving. i've gotten 51 mpg by driving 55 mph (98%) freeway.

i don't do jack rabbit starts and i shift (if you have a mt) no later than 2,500 rpm.

Yea, I struggle to get over 40mpg, as all my driving is short (under 5 miles) city driving. And now, I'm actually doing City city driving, tons of stop lights that are not predictable, my milage has suffered. I've had my car for 6 months and I'm still under 4,000 miles. I guess that's good for my actually emissions per year, but I don't think I'm going to hit my goal of 45mpg if all I do is short city driving. I need to take a vacation to somewhere far so I can use a whole tank of gas going somewhere to see what I can do on all highway.

Well, BailOut gets amazing mileage not necessarily because he's driving a Yaris, but because of his driving technique, and the way he does it can't be always considered as a "normal driving" - such as turning off the engine on downhill or excessively inflating the tires way above the engineering recommendations. With some of the techniques he uses, anyone would achieve better mileage, even with cars like Escalade or Tahoe.

If one drives on highway at 50 mph instead of 65, this will increase up to 15-20% the mileage, however is it 50mph a practical speed in todays life style ?

I would drive my car at 35mpg on highway (slowest speed allowed) and tell you about 70MPG or more, would that be reasonable ?

That said, I agree with many of his driving techniques, that could easily be used by anyone with better mileage as a result, such as shifting limits or avoiding excessive speeds
